Abstract

A multi-degree-of-freedom on-line detection device for optical element damage belongs to the optical field and aims at solving the problem that the on-line detection on the damage of a multi-path optical element can not be fast achieved in a target chamber. The multi-degree-of-freedom on-line detection device for the optical element damage comprises an optical imaging platform, an angle of pitch adjusting mechanism, an overturn mechanism, a circular rotation mechanism, a gear box and a six-degree-of-freedom manipulator. An optical shaft of the optical imaging platform, the angle of pitch adjusting central axial line, the central axial line of the circular rotation mechanism and the central axial line of the overturn mechanism are crossed at the central point o in space, and the central point o coincides with a ball center of the tested target chamber. The on-line detection device achieves scanning of the optical element in the test target chamber in latitude, longitude, the vertical direction, and optical element images obtained through scanning are sent to a computer for damage on-line detection.

Description

technical field [0001] The invention relates to an online damage detection device for multi-degree-of-freedom optical elements, belonging to the field of optics. Background technique [0002] In a powerful laser optical system, high-throughput operation can easily cause damage to optical components. This is because under strong laser irradiation, the cracks in the test piece cause the light field to strengthen, and the scratches introduced in the manufacturing process will form a concentrated electromagnetic field distribution inside the material, which is easy to cause self-focusing, electron collapse and ionization, etc., directly causing the material The ability to resist damage decreases, and the strong absorption of laser energy by impurities in the subsurface damage layer will cause local high temperature, form thermal stress, and cause the material to crack or crush. In addition, the size of the damage point of the optical element will increase exponentially with the...
