New High-Temperature Thermoelectric Coolers from Laird Thermal Systems Cool Optical Sensors in Advanced Driver-Assistance Systems (ADAS)

Advanced driver-assistance systems (ADAS) use a variety of imaging sensors, cameras and lasers to enhance vehicle safety and create better driving conditions. Most of these optical devices, including CMOS sensors and laser diodes, are heat sensitive and rely on high-resolution images for proper operation. Image quality can quickly deteriorate as the device temperatures rise above 60°C.

Next Gen Thermoelectric Coolers for Optoelectronics

Date: Monday, September 13, 2021

Time: 12:00 PM Eastern Daylight Time

Duration: 1 hour

Complex manufacturing processes require advanced thermal management solutions to support heat removal and temperature stabilization of optic systems in a wide range of applications. For example, thermoelectric coolers provide superior spot cooling for laser optics and power sources to deliver robust, low-power, and maintenance-free operation. 

Cooling Solutions for Autonomous Systems

Advances in autonomous technologies, such as smart headlights, autonomous systems for collision avoidance, and infotainment systems, require enhanced thermal protection of critical electronics to ensure optimized performance. These emerging intelligent autonomous systems are increasingly complex while decreasing in size and weight. Packing more functionality into smaller footprints has increased the heat flux density and thermal challenges in autonomous systems.

Lidar Sensors

Light detection and ranging (Lidar) is a survey-mapping technology that detects objects in 3D by measuring the time it takes for laser pulses to bounce off objects at a distance. Lidar uses light waves in a manner similar to the way radar uses radio waves or sonar uses sound waves. The sensors in the Lidar systems can read a million data points per second, enabling them to build high-quality 3D images of scanned objects or landscapes. 

Cooling for Digital Light Processors

Digital Light Processors make use of millions of micromirrors to produce vibrant, high-resolution images on a screen. The tiny micromirrors are placed on a semiconductor chip, known as a Digital Micromirror Device (DMD). This technology can be found in several industries ranging from Head-up displays and Smart headlights in the automotive market, Smartphones and other display and projection applications to advanced light control in 3D printing.

Peltier Cooling for Digital Light Processors


Digital light processors employ a laser light source and millions of tiny mirrors to produce vibrant, high-resolution images for a wide variety of industries and applications. It is critical to maintain an optimum operating temperature during use to prevent degradation of the digital light processing technology. Active cooling solutions utilizing thermoelectric coolers can provide digital light processors thermal management in a wide range of high temperature applications.
