This division is equipped with a 1000-core CPU and 15 TB memory for simulation, as well as a self-controllable high-efficiency software for optical field simulation, which can design refractive, diffractive, and meta-surface optical systems and develop image restoration algorithms. The division possesses a series of instruments and equipment, such as a four-dimensional interferometer, an 8 m collimator, a high-resolution two-dimensional turntable, a Zeiss coordinate measuring machine, a solar simulator of 200 m aperture, a JY320 monochromator, and a six-degree-of-freedom adjustment platform. Accordingly, the division is capable of conducting the digital calibration of refractive, diffractive, and meta-surface optical systems, integrated testing, and opto-mechanical calibration.
