ture of the radiometer to insure that all the light entering the radiometer has gone through the area of interest on the combiner. In the case of the LANTIRN hud, the upper, "eyebrow" section was fairly narrow (see Figure 3), making it somewhat more difficult to measure its spectral transmissivity.… … The spectral transmissivity curve can be used to calculate the photometric transmissivity through the HUD of various objects of differing speotral distributions (aolors) . If the speotral transmissivity of the combiner is flat across all visible wavelengths, then the photometria transmissivity will…
