Abstract
Laser light pulses of at least two different wavelengths are reflected off a scanning mirror. A first time-of-flight distance measurement circuit receives reflected light pulses of a first wavelength and determines distances. A second time-of-flight distance measurement circuit receives reflected light pulses of a second wavelength and determines distances. The timing of transmission of laser light pulses of differing wavelengths are adjusted, and the data buffering of converted return pulses are adjusted, to compensate for laser light source misalignment.
