Basics of Laser Radar

The Laser Radar Core

The heart of the Laser Radar is a broadband frequency modulated infrared laser (100GHz modulation), which provides a robust and eye-safe signal. The upsweep and down-sweep comparison provides simultaneous range and velocity data for measurements.
The single, wide-aperture optical path maximizes signal strength and stability. Extensive signal processing extracts interference frequencies which are directly proportional to distance. The signal intensity and signal-to-noise ratio provide a built-in check that confirms measurement quality.
