Direct detection of planets around stars can be enhanced using a rotational shearing interferometer that suppresses star infrared radiation. In a lateral shearing interferometer , two images of the test wavefront, of the same size, are superposed with a small mutual lateral displacement, as shown in . A parallel plate lateral shearing interferometer (11) allows the shearing plate (13) to oscillate through a small angle periodically causing the . PERFORMANCE COMPARISON OF SHEARING INTERFEROMETER. HARTMANN WAVE FRONT SENSORS.

Key Words: Interferometer , testing of lenses, lens aberrations, aberrations, prism interferometer ,. S, which is usually a small. This is a null method used to test the collimation of laser light whose coherence length is long compared to the . The vectorial shearing interferometer includes a pair of wedge prisms as a shearing system. Perfect alignment of the shearing system is crucial for the optimal . Instead of measuring a wavefront against a substantially error-free.
Dabei wird das zu unternde. Licht in zwei Wellen aufgeteilt und die beiden Teilwellen lateral zueinander verschoben ( Shearing ).
