Near-field diffraction of chirped gratings.
In this Letter, we analyze the near-field diffraction pattern produced by chirped gratings. An intuitive analytical interpretation of the generated diffraction orders is proposed. Several interesting properties of the near-field diffraction pattern can be determined, such as the period of the fringes and its visibility. Diffraction orders present different widths and also, some of them present ...
متن کاملLinear response deviations during recording of diffraction gratings in photopolymers.
In a holographic recording is advisable that the diffraction efficiency increases linearly with the exposure in a wide zone of the curve of diffraction efficiency versus energetic exposure and the slope of the curve must be approximately constant before saturation in order to improve the energetic sensitivity and to get reproducibility in different recordings with the same kind of photopolymer,...
متن کاملAn active interferometer-stabilization scheme with linear phase control.
We report a simple and robust computer-based active interferometer stabilization scheme which does not require modulation of the interfering beams and relies on an error signal which is linearly related to the optical path difference. In this setup, a non-collinearly propagating reference laser beam stabilizes the interference output of the laser light propagating collinearly through the interf...

15 صفحه اولAn Image Deblurring Method Using Diffraction Gratings
This paper has two major aims; to show a method for making image deblurring masks from simple Ronchi ruling diffraction gratings, and second, to show a simple means for introducing noise-reducing redundancy into an optical processing system when the processing is a one-dimensional operation, as in the case of deconvolution of a one-dimensionally blurred image. Yu has described a method for intr...
