Abstract
The present disclosure describes calibration methods for optoelectronic modules with active illumination, such as 3D ranging systems. Calibration methods include determining cross-talk calibration parameters for an optoelectronic module having an emitting channel and a receiving channel where the optoelectronic module is operable to demodulate modulated light incident on the receiving channel. Cross-talk calibration parameters are saved to a readable storage medium and recalled during distance measurements to an object or objects in a scene.
