2. Spatial light modulation: The light beam is spatially modulated through optical devices such as liquid crystal spatial light modulator (LD-SLM), and the input signal can be weighted and modulated.

3. Convolution operation: The beam after spatial light modulation is convolution operation in space through optical components such as lens and diffraction grating. The diffraction grating can realize the spatial decomposition and recombination of the beam, so that the beam is divided into multiple spots, and the calculation is carried out according to the requirements of convolution kernel.

It should be noted that the principle of optical convolutional chips is based on the interference and diffraction effects of light, and the modulation and decomposition capabilities of optical devices are used to achieve convolutional operations. This approach helps to improve the speed and energy efficiency of the operation, and can process multiple input signals simultaneously. But at the same time, the manufacture and commissioning of optical devices also pose some challenges to the performance and reliability of the chip.
