Invited Article: Optical dynamic range compression

We introduce the concept of optical dynamic range compression and discuss its utilities in the non-uniform quantization, enhancing the signal-to-noise ratio as well as reshaping signal’s statistical distribution and extending the detection range in light detection and ranging systems. The technology...
