Multiorder rotating grating interferometer.

چکیده
A multichannel interferometer that uses a rotating grating to both disperse and Doppler shift an incident far-infrared laser beam is described. The laser beam is diffracted into a fan array of many (~ 10) beams that can be directed to probe the plasma along distinct chords. The phase-shift information is multiplexed in the frequency domain so that a single detector suffices to sense the recombined probing beams.

Double Grating Interferometer with Variable Lateral Shear
A modified Ronchi interferometer using two identical gratings is described. This instrument is very suitable for the measurement of small, zonal aberrations, since the shear can be changed continuously by rotating one grating with respect to the other, while the direction and magnitude of the tilt between the sheared wavefronts can be varied by adjusting the distances of the two gratings from t...
متن کاملEfficient generation of large diffraction gratings with a grating interferometer.
The advantages of a grating interferometer for the generation of large diffraction gratings are demonstrated. In a one- and a two-stage process, high-quality gratings of 120 and 200 mm, respectively, were made with optics no larger than 50 mm together with an argon-ion laser with no line narrowing or beam stabilization and a rotating diffuser for improved beam uniformity.
متن کاملElectronically swept millimetre-wave interferometer for spatially resolved measurement of plasma electron density
We report the development and initial implementation of a new rapidspatial-scan millimetre-wave interferometer for plasma density measurements. The fast scan is effected by electronic frequency sweeping of a wide-band (180-280GHz) backward-wave oscillator (BWO) whose output is focussed onto a fixed blazed diffraction grating. The system, which augments the rotating-grating scanned multi-view H-...

متن کاملMTF measurement via diffraction shearing with optically superimposed gratings.
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.
