Aperture response and optical performance of patterned-electrode virtual-phase imagers

This report discusses the aperture response and associated optical characteristics for frontside-illuminated, frame-transfer, patterned-electrode, virtual-phase imagers under various operating conditions. These characteristics are of interest in considering the use of these imagers in camera applications. The consequences of the use of semitransparent electrodes for the clocked phase of this new class of devices is discussed, and the implications on MTF, aliasing, and performance in interlaced applications is considered.
