Abstract
A system that may include (a) a radiation source that is constructed and arranged to illuminate an object with radiation during consecutive time frames of microsecond-scale duration, wherein radiation emitted during one time frame differs by energy from radiation transmitted during an adjacent time frame; and (b) a CMOS sensor that may include a readout circuit and CMOS pixels. Each CMOS pixel may include a radiation sensing element and in-pixel memory elements. Different in-pixel memory elements are constructed and arranged to sample a state of the radiation sensing element during different time frames of the consecutive time frames.
