Journal ArticleDOI
An analysis of systematic phase errors due to nonlinearity in fringe scanning systems
TL;DR: In this paper, the authors discussed the necessary number of sampling steps to reduce under-sampling errors in a fringe scanning interferometer and some examples of the necessary sampling steps.
Journal ArticleDOI
Thermoplastic photographic material for vibration measurements by speckle photography
TL;DR: In this article, the feasibility of using thermoplastic photographic material for recording a speckle pattern image is studied experimentally to be proved true, and an optimum recording condition of the material is also obtained.
Journal ArticleDOI
Real-time in-plane vibration measurements by speckle interferometry with the aid of liquid crystal light valve
TL;DR: In this article, real-time measurements of in-plane vibrations by speckle interferometry, which employs a liquid crystal light valve to record speckles patterns, is experimentally studied to be feasible in practice, and preliminary results also shown.
Journal ArticleDOI
Interferometric Study of Microscope Objectives
Yukichi Ukita,Jumpei Tsujiuchi +1 more
TL;DR: In this article, a specially designed microscope interferometer was constructed to observe the image of a point source or periodic pattern simultaneously with wave aberration, and made a series of experiments to make clear the correspondence between the aberration and the definition of image.
Journal ArticleDOI
A null test of aspherical surfaces in scatter plate interferometer
TL;DR: In this paper, the null test of an aspherical mirror from a spherical mirror was proposed without using any special optical element, where the excess optical path difference due to an off-axis scatter point was removed.
