Double direct injection dual band sensor readout input circuit |
摘要 |
A double direct injection dual band focal plane array input circuit provides simultaneous and separate integration of the current from two sensors which share a common node. The sensors are constant voltage and variable current sensors such as HgCdTe infrared photodiodes. The sensor voltage biases are independently adjustable. Multiple integration of the signal from one sensor may be performed within one integration time of the other sensor. The circuit is used in staring infrared dual band focal plane arrays and may be used process information from more than two sensors.
