Nonlinear spatial ยฎltering is realized due to the electro-optical eect in spatial light modulators (SLMs). Optical methods with nonlinear ยฎltering are suggested for various optical applications such as optical inspection of photolithography masks, wavefront sensor, etc. A fast optical response of th
