Abstract

The degradation of space photosensors and optical devices in several radiation environments is reviewed. The effects are of concern to designers of spacecraft and ground-based systems dedicated to observation, inspection and other practical tasks. Design and prediction methods can be developed which make observation systems more tolerant to radiation effects. The methods for predicting radiation effects in light sensors, phosphors and optics are common to high-radiation in space and on the ground. In all cases, the creation of defects and the trapping of charge in silicon, insulators and transparent materials and the associated hardened technologies (such as hardened silicon, hardened oxide films, hardened fibres and ultrapure scintillators) are discussed and instruments for the measurement of radiation dose and silicon defect creation in orbit are described.
