A real-time wavefront sensing method for arbitrary targets is proposed, which provides an effective way for diversified wavefront sensing application scenarios. By using a distorted grating, the positive and negative defocus image

The infrared imaging windows of the hyper/supersonic optical dome are encountering severe aero-optical effects (AOEs), so a flow control device, the ramp vortex generator array (RVGA) is proposed based on the ramp vortex generator

The multilongitudinal mode (MLM) high-spectral-resolution lidar (HSRL) based on the Mach–Zehnder interferometer (MZI) is constructed in Xi’an for accurate measurements of aerosol optical properties. The critical requirement of the
