| description | A time-of-flight (TOF) sensor device is provided that is capable of accurately recovering waveforms of reflected light pulses incident on the sensor's photo-receiver array using a low sampling rate. A number of samples for a received light pulse incident on a given photo-receiver are obtained by emitting a light pulse to the viewing field, integrating the electrical output generated by the photo receiver over an integration period, and adding the integral values for respective integration cycles to yield an accumulation value. This process is repeated for multiple accumulation cycles; however, for each consecutive accumulation cycle the start of the integration period is delayed relative the start time of the integration period for the previous cycle by a delay period. Sampled values for the waveform are obtained by determining the difference values between consecutive accumulation values for the respective accumulation cycles. |
