MTF measurement via diffraction shearing with optically superimposed gratings.
نویسندگان
چکیده
The use of double grating diffraction shearing for measurement of MTF is demonstrated. By superimposing two gratings optically we avoid the problem of grating contact and subsequent degradation. This simple and economical method is especially advantageous for optical systems with large pupil for which a rotating plate interferometer becomes prohibitively expensive.

Harmonically-related diffraction gratings-based interferometer for quadrature phase measurements.
We demonstrate the use of shallow diffraction gratings for quadrature phase interferometry. A single shallow diffraction grating-based Michelson interferometer yields only trivial (0(o) or 180(o) ) phase shift between different output ports. In comparison, a combination of two parallel shallow diffraction gratings can be useful to achieve desired phase shifts (e.g., 90 (o) for quadrature phase ...
متن کاملSuperimposed Nano-scale Diffraction Gratings as High Capacity Barcodes for Biological and Chemical Applications
We describe a new non-contact high capacity optical tagging technique based on the use of nanostructured barcodes. The tags are generated from a number of superimposed diffraction gratings. With one-dimensional diffraction, capacity for up to 68,000 distinguishable tags has been demonstrated, with a theoretical capacity of up to 109 tags. Extension into two dimensions increases this theoretical...
متن کاملShearing Interferometer Using Four Gratings
Abstract: This paper describes a shearing interferometer with four diffraction gratings for dividing light waves. It allows us to use an extended white light source. This feature of the interferometer is discussed and demonstrated by experiments. By constructing the interferometer for testing transparent object, phase distribution of the light wave passing through an optical lens is measured wi...
متن کاملDiffraction from metallic gratings with locally varying profile forms.
Measurements of the diffraction characteristics of one-dimensional surface-relief gratings of locally varying profile are compared with rigorous diffraction theory. These gratings result from the superposition of two linear sinusoidal gratings of uniform depth for which the relative phase between the two gratings varies slowly with position. The resultant surface profile exhibits a relatively l...
متن کاملDiffraction gratings in sol–gel films by direct contact printing using a UV-mercury lamp
We report on the fabrication of diffraction gratings in photosensitive sol–gel thin films by direct contact printing using a UV-mercury lamp. Titanium amplitude masks were used to replicate diffraction gratings into photosensitive sol–gel films by contact printing with an incoherent UV-light source. Gratings with 1-mm period were fabricated in sol–gel films. The diffraction efficiencies of each...
