Transient response of IR detectors used in space astronomy: what we have learned from ISO satellite

摘要

Doped silicon and germanium bulks with implanted low ohmic contacts are extensively used as extrinsic photoconductors for infrared astronomy from ground based, ballon, airborne and space observatories. These detectors are characterized by temporal transient effects after flux change, which can bias the photometry by significant factors. A systematic correction of these effects can significantly reduce the observing time and improve the final accuracy.
