Infrared Sensors are electronic devices that use infrared radiation to perform a variety of functions across a wide range of applications from consumer electronics to industrial automation to medical and scientific research to military and aerospace.
LiDAR (light detection and ranging) is a survey-mapping technology that detects objects and distances in 3D by measuring the time it takes for laser pulses to bounce off objects at a distance. Thermal management is crucial to most laser systems, and LiDAR lasers are no different. Stable temperatures within LiDAR systems are essential for optimal performance, as temperature fluctuations can lead to changes in laser wavelength and increased range errors. Excessive heat can degrade laser performance, reduce reliability, and even lead to component failure if not adequately managed.
Vertical-cavity surface-emitting lasers (VCSELs) are a type of semiconductor laser that emits a circular, low-divergence beam of light perpendicular to the surface of the chip, as opposed to edge-emitting lasers that emit parallel to the chip surface. This beam quality simplifies optical system design and improves coupling efficiency. VCSELs are characterized by their unique structure, which consists of a thin layer of active semiconductor material sandwiched between two highly reflective mirrors.
