摘要
We describe a straightforward "multiple-read" software algorithm which reduces the read noise of a state of the art infrared array detector - the Santa Barbara Research Corporation (SBRC) 58 × 62 InSb array - by a factor of order 5. We demonstrate this gain in performance directly in a low-background application using the KPNO Infrared Grating Spectrometer (CRSP) for a measurement of vibrationally excited molecular hydrogen emission from the proto-planetary nebula CRL 2688. We anticipate that the noise reduction scheme described here may be generally applicable to present-day infrared arrays.
