To continue our earlier research on novelty filters in a system of incoherent light [ Opt. Lett. 30, 81 ( 2005)], we discuss the relationship between parameters of a bacteriorhodopsin film and the quality of a novelty filter image. For both fixed and moving velocities of the input image, differences in the novelty filter’s image as a function of thickness, lifetime of the M state, and molecular concentration are displayed, and the optimal ranges of parameters of the bR film that correspond to the entire novelty filter image and obvious gray-level differences in the image are given. The method can be used to design high-quality novelty filter images in incoherent light systems.
