Abstract
Two or more imagers having associated frame rates are each configured with a global shutter having an exposure interval less than a frame interval. The exposure interval for a first imager is offset from the exposure interval of a second imager such that the first imager is exposed while the second imager is not exposed. When interleaved, an effective frame rate exceeds the individual frame rates provided by the individual imagers. This interleaved imaging system may be used to recover, at high frame rates, images that are projected from spatial light modulators.
