Abstract
Techniques are disclosed for radiation sensors that generate current signal to provide flexible placement of one or more integration intervals between resets of an integration capacitor. With flexible timing, an embodiment of the present invention provides several modes of operation including: multiple stray light blanking interval to occur during the integration cycle; range gating for LIDAR applications; time-delay-integration (TDI) with multiple short integration periods between frame resets; and hyper-resolution gating that provides better resolution than is normally possible with a fixed gate width. Numerous variations will be apparent in light of this disclosure.
