Operating a spatial light modulator or SLM 201 having a first input pattern on a first subset of pixels 221, a first filter pattern on a second subset of pixels 222, a second input pattern on a third subset of pixels 223, a second filter pattern on a forth subset of pixels 224, and performing a first and second optical correlation. The first input pattern is representative of a first input image. The first filter pattern is representative of a first reference image. The second input pattern is representative of a second input image. The second filter pattern is representative of a second reference image. The first optical correlation is performed between the first input image and the first reference image. The second optical correlation is performed between the second input image and the second reference image. |
