Radiation hardening methodology applied on absolute optical encoder of a total dose beyond 100 kGy

Abstract

The goal of this study is the conception of a radiation tolerant absolute optical encoder. This paper describes the design methodology and results of characterization under Co/sup 60/ radiations up to a total integrated dose of 100 kGy(Si). This hardening design can be used to produce equipments with total dose specification more than 100 kGy(Si).
