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 Autonomous

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. 

The lasers in Lidar systems, particularly those used in outdoor autonomous applications, require active cooling to achieve maximum resolution in high-temperature environments. As temperatures increase, the wavelength of the laser changes, resulting in increased range error. Maintaining operational temperatures within a Lidar system’s temperature limits ensures peak performance. 

Laird Thermal Systems Solutions

High-performance thermoelectric coolers offer a flexible active cooling option for spot cooling of Lidar sensors. 

The OptoTEC™ OTX/HTX Series is a high-performance miniature thermoelectric cooler offering superior temperature stability in a very small footprint to accommodate applications with tight geometric space constraints such as Lidar systems.

The HiTemp ETX Series is a new generation of thermoelectric coolers with advanced thermoelectric materials, delivering precise temperature control in high temperature environments.
