WebIn seismic interferometry the time-reversed responses are not physically sent into the earth, but they are convolved with other measured responses. The effect is essentially the same: The time-reversed signals focus and create a virtual source which radiates waves into the medium that are subsequently recorded by receivers.

Pseudo-Shear Interferometry

WebRonchi interferometry is an optical testing technique similar to shearing interferometry. A coherent wavefront is interfered with a sheared form of itself by placing a periodic grating at, or near, the focus of an optical system. The resultant interference pattern contains information about the wavefront's slope in a direction perpendicular to the grating … WebBasics of Interferometry, 2nd Edition by P. Hariharan.

WebAdvanced Search >. Home > Proceedings > Volume 0429 > Article Translator Disclaimer WebSometimes called pupil-plane interferometry, Michelson type shearing interferometers measure the coherence between different points on the wavefront by splitting the incoming light and then shearing one beam with respect to the other. Each of the three types performs a different shear on the wavefront.

The shearing interferometer is an extremely simple means to observe interference and to use this phenomenon to test the collimation of light beams, especially from laser sources which have a coherence length which is usually significantly longer than the thickness of the shear plate (see graphics) so that the basic condition for interference is fulfilled. WebJun 1, 2024 · Illumination integrated non-uniformity (IINU) is one of the key factors to determine the resolution and Critical Dimension Uniformity (CDU) which are important performance parameters in advanced lithography system. To further reduce the IINU, uniformity correction technology has been adopted.
