Abstract

The invention relates to a transmissive liquid crystal optical phased array drive and control system, which mainly includes a signal converter 1 and a signal transmitter 2 which are VC programs running in the operating system of a PC; a PCI drive controller 3 and a FIFO buffer 4. The signal converter 5 is a Verilog program running inside the data acquisition card; the FIFO buffer 6 and the liquid crystal controller 7 are Verilog programs running inside the FPGA target board. The transmission type liquid crystal optical phased array drive control system of the present invention, through the high-precision control and sampling of the voltage input end of each pixel electrode, the high-speed switching and accurate control of multi-channel signals, has high orientation accuracy and orientation speed, and is a transmissive The liquid crystal optical phased array provides a drive and control system that can be used in practice, and lays the foundation for the realization of the transmissive liquid crystal optical phased array equipment.

Description

technical field [0001] The invention relates to a drive and control system for a transmissive liquid crystal optical phased array, which belongs to the field of optomechanical integration technology. Background technique [0002] With the development of high technology, offensive weapons are developing in the direction of fast, small and stealthy, and the trend of accelerated development is obvious. For example, the hypersonic missiles and hypersonic aircraft being researched by Western military powers will form combat effectiveness within 5 to 10 years. Such weapons are fast. If missiles, artillery or powerful lasers are used for interception, it is often necessary to detect and identify targets tens of kilometers or even hundreds of kilometers away. Existing tactical radars can no longer meet the requirements. [0003] Due to the short laser wavelength, LiDAR is an ideal equipment for early warning and identification of small targets within 100 kilometers. However, the l...
