Paper Abstract

A large-scale optical system with a primary mirror, 82" diameter, is presently being constructed in order to make scattering measurements from infrared to visible wavelengths on large objects. The necessity of having a spherical primary mirror and finite field of view lead to a three-mirror design. The need for low mirror backscatter required separate transmitting and receiving optics with only the primary common to both systems. The background behind the target is in the field of view; control of the resulting backscatter is discussed. Scatter from the room walls and objects in the room is analyzed for various test conditions. BRDF measurements were made on coated and uncoated Cervit samples in an effort to validate the predicted primary mirror scattering.
