Performance
Scientific paper
An existing 10.6 micrometers CO2 laser bi-directional reflectance distribution function (BRDF) station was converted into a small scale off-axis rejection (OAR) facility for testing the point source transmittance (PST) of an infrared (IR) sensor cold shield at room temperature with a room temperature detector. A cold shield with a defective coating was identified; the coating was refurbished and performance remeasured. An improved performance was observed. A simple Gaussian integration technique for total transmitted energy was applied to assess performance in the sensor. Construction of a combined BRDF/OAR facility for component and telescope testing is discussed.
