Abstract

The importance and description of the control and suppression of stray light has been discussed and reviewed in several articles. The two basic methods of reducing stray light are by directional control and suppression through absorption. The added complexity of advanced optical systems due to more strigent requirements and longer lifetimes require an evaluation of the effectiveness of these methods. The type and accuracy of Bi-directional Reflectance Distribution Function (BRDF) databases will be addressed. Extra-polation of data to other wavelength regions will require credible scattering theories and scaling relations. An assessment of the type and need of facilities for stray light measurements at both the component and system level will be made. Contamination criteria are becoming increasingly important with longer lifetimes and will be discussed with respect to cryodeposition and outgassing of materials defined by system design. Approaches of evaluation of the stray light rejection characteristics of a total optical system will be compared and assessed. Tradeoffs and advantages of experimental measurements will be made. Trends in computer simulations will be identified.
