Abstract:
Integrated Filter-Detector Elements
Performance of present and planned electro-optical sensors could be significantly
improved with the incorporation of filters deposited directly onto detector elements.
The use of ion-assisted deposition and ion-beam sputtering in the fabrication of
detector filter coatings will be investigated. These processes can be carried out
at a low temperature and can be used to deposit a wide variety of optical coating
materials. Issues such as process, filter and detector material compatibility, patterning
techniques, and risk reduction will be addressed.
Principal initial applications will be in space-based sensors, in which ultimate
performance, power and weight savings, and reliability are critical. Later applications
include spectroscopic detector arrays with integral order sorting filters and low-cost
disposable filters and sensors for patient monitoring.
