A thousand-unit scalable wave-front detector based image restoration technology was proposed. The wave-front detection and image restoration were combined to eliminate the effect of atmospheric disturbance and system aberration on the image resolution and to meet the requirements of large ground-based telescopes for high-resolution imaging. First, the wave-front detection was used to obtain the wave-front aberration and then degenerated images were restored based on obtained aberration amounts. The core component, a wave-front processor, used a wave-front host Printed Circuit Board(PCB) combined with a wave-front sub PCB to implement wave-front processing for optical systems with different sizes and it could reach thousand magnitude unit outputs. An image restoration experiment for a laser source was performed in an experimental laboratory, which shows the laser energy concentration has increased by 50%. And the binary source of 0.6 arc-second experiments was carried out in a telescope, and its Full Width at Half Maximum (FWHM) has decreased by 80%. By using a large-scale Field Programming Gate Array(FPGA) as the core processing device, the system achieves the high resolution image restoration for a degenerated image from the ground-based telescope.
