Fast Wavefront Sensor Development
A beam control system with a fast wavefront sensor (WFS) is needed for long range beam delivery through the atmosphere and especially through fast aero-optic aberrations. The WFS must be fast to respond to changes in atmospheric disturbances, inexpensive to be practical, and small enough to be portable and integrated anywhere. Previous WFS designs are often too large, expensive, or slow due to limitations of existing computational and sensor hardware. We have developed an adaptive optics system which utilizes modern video transfer protocols via multi-gigabit transceivers on an FPGA. Building upon our existing high frame rate digital wavefront sensing improvements, we have developed an electro-optical architecture for sensing at frame rates exceeding 200,000 fps enabling the potential for detection and compensation of extremely fast disturbances. We present here the new architecture and initial hardware demonstrations of this capability.
