Widefield heterodyne interferometry using a custom CMOS modulated light camera.
In this paper a method of taking widefield heterodyne interferograms using a prototype modulated light camera is described. This custom CMOS modulated light camera (MLC) uses analogue quadrature demodulation at each pixel to output the phase and amplitude of the modulated light as DC voltages. The heterodyne interference fringe patterns are generated using an acousto-optical frequency shifter (...
متن کاملLaser Phase Noise Rejection by Two-wave Mixing Photorefractive Interferometry
INTERFEROMETRY M. Dubois 1 and T. E. Drake General Electric Global Research, Schenectady, NY, USA; Lockheed Martin Aeronautics Co., Fort Worth, TX, USA Abstract: Laser-ultrasound is a technique currently used for the ultrasonic inspection of composites during manufacturing of advanced jet fighters. This technique is based on a shortpulse laser to generate ultrasonic waves and a long-pulse laser...
متن کاملDiode Laser Frequency Standard for Laser Interferometry
Diode lasers are becoming increasingly important in length metrology. We demonstrate construction of a simple single-frequency diode laser 632,8 nm, used as a frequency standard in the laser interferometers. We present two different systems applied for frequency stabilization of diode laser . For diode laser used as the secondary standard, the system stabilizes diode temperature, the frequency ...
متن کاملTwo-dimensional effects in laser-created plasmas measured with soft-x-ray laser interferometry.
Soft-x-ray laser interferograms of laser-created plasmas generated at moderate irradiation intensities (1 x 10(11)-7 x 10(12) W cm(-2)) with lambda=1.06 microm light pulses of approximately 13-ns-FWHM (full width at half maximum) duration and narrow focus (approximately 30 microm) reveal the unexpected formation of an inverted density profile with a density minimum on axis and distinct plasma s...
متن کاملTwo-Photon Counting interferometry
Two-photon counting (TPC) interferometry has been realized by measuring the electrical current due to two-photon absorption in the space charge layer of a semiconductor detector located at the output port of an interferometer. We apply this technique to study the correlation properties of twin beams issued from parametric fluorescence. We describe in details how the different second-order corre...
