Multi-color superpixel operational constructs for focal plane arrays

摘要

A method for sensing using a multi-band photovoltaic detector, the method including biasing the photovoltaic detector using a bias voltage at a mid-point of a detector substrate bias voltage range, selecting a first band of the multi-band photovoltaic detector, sensing a first current from a first diode of the multi-band photovoltaic detector, the first diode being associated with the first band, selecting a second band of the multi-band photovoltaic detector; and sensing a second current from a second diode of the multi-band photovoltaic detector, the second diode being associated with the second band.
