Abstract
In accordance with certain embodiments of the present technology, edges of light drive pulses, which are produced by a light source driver and are used to drive a light source, are aligned with edges of light reference pulses that have a predetermined fixed delay relative to light timing pulses. This way, light pulses are emitted by the light source at precisely known times, so that accurate time-of-flight (TOF) measurements can be made. Additionally, edges of shutter drive pulses, which are produced by a shutter driver and are used to drive a gated light detector, are aligned with edges of shutter reference pulses that have a predetermined fixed delay relative to shutter timing pulses. This way, the gated light detector is shuttered on at precisely known times, so that accurate TOF measurements can be made.
