| titleOfInvention | Corrugated phase measurement method based on four beam interferences |
| abstract | The present invention provides a kind of corrugated phase measurement method based on four beam interferences, and detailed process is：Wave-front division element is set in the plane that light wave wavefront to be measured is located, four thang-kngs circular hole A, B, C and D are provided with each sub-aperture on the wave-front division element, wherein the center of circle of thang-kng circular hole A is located in sub-aperture in the heart, and the center of circle of thang-kng circular hole B, C and D is spaced 120 ° and is distributed on the concentric circular of thang-kng circular hole A；Photoelectric sensor gathers the interference pattern of light wave formed light field Jing after wave-front division element, and is stored in memorizer；According to the interference pattern in i-th sub-aperture, the corrugated phase mehtod that light wave wavefront to be measured is characterized with slope, curvature and mixing curvature value on the x and y direction of corrugated in described i-th sub-aperture of wave-front division element is calculated arithmetical unit.The corrugated phase information that with corrugated x and y direction on slope, curvature and mixing curvature value characterize is obtained in that in each sub-aperture using the method, so as to realize the accurate measurement of higher order aberratons. |
