FPGA Technology

A Field Programmable Gate Array (FPGA) is a highly versatile integrated circuit that can be configured and reprogrammed after manufacturing to perform a wide range of digital functions. Unlike fixed-function chips, FPGAs provide exceptional flexibility, enabling rapid prototyping, customization, and parallel processing to meet evolving application needs. Their reconfigurable architecture makes them ideal for complex, high-performance tasks in telecommunications, automotive systems, aerospace, and cutting-edge photonics.

The image above shows the FPGA used for this project. It controls how each pixel of the Liquid Crystal on Silicon (LCoS) panel turns on or off, determining the diffraction patterns formed. By programming each pixel individually to be either active or inactive, the FPGA dynamically modulates the light reflected by the LCoS, enabling precise control over the optical output.
