Abstract :
A high-resolution Shack-Hartmann sensor is developed, which enables one to perform the fast time sampling and measuring both the wavefronts and the intensity distributions of high power lasers over the square entrance pupils up to 15×15 mm. The sensor has a flexible program interface with two built-in algorithms for reconstructing the laser wavefronts.
