Transitioning optical processors from the laboratory to rugged environments requires special care during the design of the optical and mechanical components as well as the total package configuration. Processors exist today that were developed to operate in various rugged environments while maintaining performance specifications. Designing optical processors for space environments requires additional consideration of features such as radiation, launch vibration, thermal cycling, heat dissipation, self calibration, and autonomous operation. This paper presents the design of processors which operate in rugged environments, and the rules that must be adapted/extended space operation. Specific experience and general conditions are presented on existing processors and those under development. The status of radiation hardened components is also presented.
