Abstract
Methods and systems for providing eye-safe compatible receiver for a light detection and ranging system. The light detection and ranging system comprises; an emitting unit comprising a light source configured to emit a sequence of light pulses of a first wavelength into a three-dimensional environment; and a receiving module comprising a detector for detecting light pulses of a second wavelength, in which the second wavelength is shorter than the first wavelength, the receiving module further comprising a wavelength converter coupled to the detector and configured to convert an echo signal of the emitted light pulses into the light pulses of the second wavelength.
