Characterization of NICMOS detectors for space astronomy

摘要

Abstract: The NICMOS camera to be used on the Hubble Space Telescope will acquire near-infrared images with extremely high spatial resolution. To extract scientifically useful data from these images will require a complete understanding of the arrays used to produce the images. The NICMOS team has developed a program for characterizing arrays which will lead to this understanding and which will also allow selection of optimum devices for each section of the NICMOS instrument. The overall plan will be described and related to the scientific goals of NICMOS. The characterization plan includes standard infrared array testing such as electrical properties, read noise, dark current, and quantum efficiency, and will be expanded to include testing such as crosstalk measurements, hysteresis testing, and radiation testing.!3
