Abstract
The utility model discloses a strip-shaped light spot wavefront testing device comprising a spherical lens I, a cylindrical lens I, a cylindrical lens II, a spherical lens II, an attenuation sheet, an optical filter, a lens array, a camera, and an acquisition system, which are sequentially arranged on an optical path. The spherical lens I and the cylindrical lens I can be used to form an objective lens, and the cylindrical lens II and the spherical lens II can be used to form an ocular. The objective lens and the ocular can be combined together, therefore original wavefront information of a laser beam can be remained, and the beam compressing having different multiplying powers of an incident strip-shaped light spot in two directions can be realized, before the incident strip-shaped light spot arrives at the camera by passing through the combined lens. The acquisition system can be used to realize the strip-shaped light spot wavefront test. The strip-shaped light spot wavefront testing device has advantages of simple structure, easy processing and adjustment, low costs, and high testing precision.
