An optical processing system comprises at least one spatial light modulator, SLM, configured to simultaneously display a first input data pattern (a) and at least one data focusing pattern which is a Fourier domain representation (B) of a second input data pattern (b), the optical processing system further comprising a detector for detecting light that has been successively optically processed by said input data patterns and focusing data patterns, thereby producing an optical convolution of the first and second input data patterns, the optical convolution for use in a neural network.
A method to incorporate multiple independent optical correlators into one system. By "independent optical correlator," we mean an optical correlator comprising of an input SLM, filter SLM, and camera, combined with appropriate coherent illumination and Fourier transforming lenses. By "one system" we mean a single optical system which utilises the elements of each of the independent correlators multiple times.
A method for assessing the relative alignment of a first and second diffractive element. The method includes illuminating the first diffractive element to form a first diffraction pattern in the far field and illuminating the second diffractive element to form a second diffraction pattern in the far field. The method further comprises determining a positional and/or rotational relationship between the first diffraction pattern and the second diffraction pattern in the far field.
