Abstract

A technique for optically implementing nonlinear gray-level transformations on images via a spatial light modulator (SLM) coupled to a computer image-processing system is presented. Both the exponential and the logarithmic functions are implemented. The only restriction in the choice of nonlinear transformations is that they must lie below the SLM's linear intensity output versus intensity input curve obtained with the SLM set to a full transmittance.
