Claim Text:
1. A method for sensing using a multi-band photovoltaic detector, the method comprising: 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; re-biasing the photovoltaic detector using the bias voltage at the mid-point of the detector substrate bias voltage range; 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.
