Abstract:
1. An imaging system comprising: a human interface device to emit infrared light; a sensor array of sensor elements to convert incident light to detections; detection accumulators; switches to couple said detection accumulators to said sensor elements, each switch selectively routing detections from a sensor element so that they are partitioned among n≧3 members of a set of said detection accumulators to yield n concurrent accumulations, wherein one of the n concurrent accumulations corresponds to the infrared light emitted by the human interface device; and a readout subsystem to read out said accumulations after they become interleaved such that, at a given instant, a first accumulation in a first accumulator of said charge accumulators includes a first portion and a second portion, and a second accumulator of said charge accumulators includes a third portion accumulated after said first portion and before said second portion.
