An angular displacement interferometer based on total internal reflection
نویسندگان
چکیده
This paper describes a new angular displacement interferometer based on the internal-reflection effect. In order to make use of the internal-reflection effect, a novel prism assembly is designed, which yields a very compact optical configuration. As a result, the linearity of the angular displacement interferometer is greatly improved. Both the linearization of the measurement equation and the experimental verification of the analysis have been conducted and the results are presented here in detail. The main factors affecting the angle measurement are also addressed. The results of the experimental verification are in good agreement with the theoretical analysis.

Small-Angle Measurement of Laser Beam Steering Based on Total Internal-Reflection Effect
A precision small-angle measurement system is introduced based on optical total internal reflection effect. When the incident angle of a polarized beam is larger than the critical angle, and the beam has a small steering angle in the vicinity of the critical angle, the total internal reflection will take place and a relative phased shift between the sand the p-polarized components is produced. ...

Total internal reflection fluorescence microscopy (TIRFM) is an optical technique that allows imaging of a thin layer of the sample with a thickness of about 100-200 nm. It is used in science of cell biology to study cellular processes, especially near the membranes of living cells. This method is based on the total internal reflection phenomenon, where the evanescent wave is generated in the l...

A small-displacement sensor based on total-internal reflection theory and surface plasmon resonance technology is proposed for use in heterodyne interferometry. A small displacement can be obtained simply by measuring the variation in phase difference between s- and p-polarization states with the small-displacement sensor. The theoretical displacement resolution of the small-displacement sensor...

متن کاملTime-domain measurements of reflection delay in frustrated total internal reflection.
We present experimental evidence that the contribution of the Goos-Hänchen shift to tunneling delay is suppressed in frustrated total internal reflection. We use a Hong-Ou-Mandel interferometer to perform direct time measurements of reflection delays with femtosecond resolution at optical frequencies, and take advantage of a liquid-crystal-filled double-prism structure to dynamically change the...
