Development of ?500 mm array-lens beam sampler

A new method to perform the large aperture beams sampler with array-lens was put forward. An 25×25 array-lens of wavefront distortion measurement was designed, and an experimental system was settled up. The perfect parallel beam is used to demarcate the large aperture array-lens wavefront sampler. And a large aperture wavefront of distortion was measured by the set. That the experiment result is in accordance with the theoretical calculation.
