| 中文摘要 | in order to measure the diffraction-limit wavefront, we present three types of common-path double-shearing interferometers based on the theory of double shearing. two pairs of half-aperture or whole-aperture wedge plates are used to introduce opposite tilt to realize the double-shearing function. by comparing the fringe widths in two fields, the marginal wavefront aberration can be obtained. in the paper, we give three different configurations: half-aperture configuration, whole-field configuration and double-interferometer configuration. the half-aperture configuration has the features of high sensitivity, stabilization and easy alignment. for the whole-field configuration, the interference fringes are displayed in two whole fields. consequently, the divergent or convergent characteristic and aberration types of a wavefront can be identified visually. the whole-field configuration can be changed to the double-interferometer configuration for continuous test. both small and large wavefront aberrations can be measured by the double-interferometer configuration. the minimum detectable wavefront aberration (w-0)(min) comes to 0.03 lambda. lastly, we present the experimental results for the three types of double-shearing interferometers. |
