Multiwavelength laser interferometry with semiconductor laser source
SPIE Proceedings, 2010First set-up of the laser interferometer with tunable semiconductor laser is presented. To reduce the influence of the index of refraction of air, the design of optical set-up of the experimental interferometer is realized using fiber optics. VCSEL diodes (Vertical Surface Emitting Laser) and DFB laser diodes (Distributed FeedBack) were used in our ...

Sound Recording by Laser Interferometry
Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009A Fabry-Perot etalon is used to form a novel type of microphone. Refractive index dependant transmission is proportional to sound pressure over a large dynamic range. The current of the laser diode is tuned to take into account environmental influences.

Particle sizing using laser interferometry
Applied Optics, 1977The theory and conditions are summarized under which single spherical particles in the size range of a few micrometers and larger may be sized using the observed fringe visibility in a cross-beam laser velocimeter. Scalar diffraction theory and experimental data are presented to show how the size information in the forward- scattered light is dependent
