METHOD OF MEASURING OPTICAL CROSSTALK IN A TIME OF FLIGHT SENSOR AND CORRESPONDING TIME OF FLIGHT SENSOR

摘要

Time of Flight Sensor A method of measuring optical crosstalk in a time of flight sensor, which comprises a substantially transparent cover covering a light emitter and one or more photodetectors. The method comprises emitting a series of pulses of light from the light emitter; and using the one or more photodetectors to obtain a distribution of times at which at least one photodetector of the one or more photodetectors detected photons after each emission of the series of pulses of light. The method further comprises recording one or more parameters of the earliest peak if the distribution comprises two or more separate peaks.
