Simulating the impact of laser eye protection on color vision

Laser eye protection (LEP) imparts coloration to the visual scene observed by the wearer, which can make interpreting color information problematic. A model has been developed to allow rapid visualization of the impact of LEP on the appearance of reflective color patches and emissive displays. This model uses the transmission spectra of LEP and spectral information of color stimuli, in conjunction with an implementation of the CIECAM02 model to account for complex aspects of human vision including chromatic adaptation. Applications include training LEP users of anticipated color shifts and iterative testing of LEP and display designs to optimize color presentation. (DSTL/JA87054)
