The optical scanner is at the heart of the perception systems we’re increasingly using in cars, in drones, and in virtual reality (VR)/augmented reality (AR)/mixed-reality (MR) headsets. In automotive, we may see a combination of cameras, LiDAR and radar used in advanced driver assistance systems (ADAS), such as automatic braking, lane-departure warnings, and collision avoidance. That’s typically the case for autonomous navigation in cars and drones as well. The optical systems in VR/AR/MR headsets feature a display—such as an OLED or LED, and cameras; and one day soon LiDAR may augment or replace those cameras. Whatever their underlying scanning technology, perception systems require micro-optical components that are accurate, reliable, affordable and available in mass-production volumes.

With so many different types of micro-optical components available for perception systems, how can designers choose the best components for their specific applications? As with any important engineering decision, you have to balance what’s most important to your customer.

Chances are, you’re looking for a compelling set of features at an affordable price point.

If you’re designing perception systems for ADAS, autonomous navigation or AR/VR/MR, it’s time to start looking at the next generation of LiDAR sensor. Because the LiDAR of old—fragile, large, expensive, susceptible to environmental conditions, and difficult to maintain—is a thing of the past. Leveraging a new topology for MEMS, Omnitron Sensors is introducing a small, low-cost, rugged and reliable step-scanning sensor for LiDAR. Omnitron’s MEMS step-scanning sensor makes a world of a difference in autonomous navigation—interpreting the real-world physical environment that a car perceives in 3D, not 2D.

And that’s just scanning the surface of what Omnitron Sensors can do. Its next-gen LiDAR sensor perceives the environment accurately in all lighting and weather conditions. It can decipher between stationary and moving objects, is immune to high-vibration and temperature variation, and it’s affordable in mass-production quantities.

Omnitron Sensors Co-founder & CEO Eric Aguilar will present “Transforming Optical Scanning: MEMS Topology for Low-Cost, Small, and High-Performance Scanners,” at 12:15 p.m. EDT on August 3, 2023.

Innovation in MEMS—and Elsewhere—Starts with Market Disruption

When Thomas A. Edison invented the phonograph in 1877, he first envisioned its use for letter writing and other forms of dictation, but he didn’t foresee that his invention would one day transform the way that people listen to music, expanding that experience from live performance only to recorded music in the comfort of one’s own home.

Let’s go one step further. Read this excerpt from the December 22, 1877 issue of Scientific American with a modern eye, and you might think that Edison’s work portended the invention of AI-enabled chatbots that mimic human conversation: “Mr. Thomas A. Edison recently came into this office, placed a little machine on our desk, turned a crank, and the machine inquired as to our health, asked how we liked the phonograph, informed us that it was very well, and bid us a cordial good night.”

On a literal level, we can’t draw a linear connection, but on a conceptual level, Edison was onto something. His work—as well as that of other pioneers who followed him closely, including Alexander Graham Bell—laid the foundation for future voice and acoustic applications, including smart speakers, cellular phones, and digital audio books.

Innovation in MEMS has progressed similarly. It has not always moved in a linear fashion, but there have been flashes of brilliance along the way. The first MEMS accelerometers in air bag crash sensors, commercialized by Analog Devices in the mid- to late 1990s, proved that MEMS devices can be manufactured in high volume and used in environments with high vibration and wide temperature variation. The Nasiri-Fabrication platform, which InvenSense used to manufacture the first high-volume MEMS gyros for consumer applications in the early 2000s, was another major leap in innovation.

Here we are in 2023, with billions of MEMS sensors now deployed in thousands of different electronic applications, and innovation has stagnated. Our industry still contends with the limitations of non-standard processes and packaging approaches, long design-to-delivery life cycles, varying degrees of high cost, and issues with reliability and accuracy. Despite this, MEMS technology has unlimited upside potential. All we need to do is fix it at a foundational level.

That’s what we’re doing at Omnitron Sensors. We’re disrupting the market with a new topology for MEMS that simplifies fabrication to improve capacitance, increase ruggedness, improve yield, speed design-to-manufacture, and reduce cost. And it’s through our new topology for MEMS that we’re able to build better MEMS devices that span markets and applications, from the first MEMS step-scanning mirrors for LiDAR to better IMUs, better actuators, and better pumps.

Why Isn’t LiDAR in Every Autonomous Navigation System?

The mechanical engineer Karl Friedrich Benz invented the first motor car powered by a gasoline combustion engine in 1884/1885. Benz, Gottlieb Daimler, Wilhelm Maybach and other pioneering inventors of early motor cars would have been hard-pressed to imagine modern cars, many of which offer advanced driver assistance systems (ADAS) that improve automotive safety, independent of the operator.

The possibility of fully self-driving cars, self-flying cargo planes, and package-delivery drones would have seemed even more far-fetched to these 19th-century engineers. But as 21st-century engineers, we recognize that ADAS, robotic cars, drones, and industrial robotics—all applications featuring some level of autonomous functionality—are not pie-in-the-sky imaginings. And the key to realizing them commercially is the perfection of LiDAR.

LiDAR—which stands for light detection and ranging—is essential to autonomous navigation. In fact, it does so much more than the more mature vision technologies, cameras and radar, which are also used in autonomous systems. Only LiDAR provides depth and functions seamlessly at all levels of light. It also delivers phenomenal resolution, so it can perceive both moving and stationary objects—another critical advantage over cameras and radar.

Given LiDAR’s technical strengths, why isn’t it ubiquitous?

As a sensor IP company with an executive team that also has years of experience with LiDAR, we’ve given this a lot of thought. And we’d like to share this with you.

Innovation in MEMS Starts with Its Topology

The first iPhone rolled out in mid-2007. It had a single MEMS device—a 3-axis accelerometer—and one each of a simple proximity sensor and ambient light sensor. The iPhone 14, on the other hand, has multiple MEMS microphones, a LiDAR sensor for face recognition, a high dynamic-range gyro and high-g accelerometer, a barometric pressure sensor, a haptic touch sensor, a proximity sensor and dual ambient light sensors. While approximately $1B of the $6+B overall MEMS market came from consumer and mobile in 2007, analysts predict that by 2026, $11.27B of the overall $18.2B will come from consumer and mobile.

That’s just consumer and mobile, of course. The first major commercial MEMS design was an Analog Devices accelerometer used in automotive crash-detection air bags in the mid-1990s. And now, MEMS technology is ubiquitous in automotive advanced driver assistance systems (ADAS) and will soon become the core enabling component in LiDAR sensors.

Still, given the many attributes of MEMS, why hasn’t its growth trajectory mirrored that of the semiconductor industry? MEMS, after all, offers unprecedented sensory intelligence in a small package, making it highly attractive for almost every application.

We’ve asked ourselves why MEMS hasn’t come farther, faster so many times over the years, and we’ve always come to the same conclusion: The slow growth of MEMS has nothing to do with its capabilities and everything to do with its manufacturing challenges. Solving those challenges was a catalyst for launching Omnitron Sensors.

At Omnitron we’ve developed a new topology for MEMS. We started by developing test structures and process steps with our foundry partners. We forged ahead to make significant improvements in capacitance to produce robust, rugged devices. The good news is that we’ve verified our process through fabrication, and are on the path to build hundreds of millions of low-cost, reliable, repeatable MEMS devices at commercial MEMS foundries.
