Multipoint laser Doppler vibrometry using holographic optical elements and a CMOS digital camera.

چکیده
A laser Doppler vibrometer (LDV) is described in which holographic optical elements are used to provide the interferometer reference and object illumination beams. A complementary metal-oxide semiconductor camera, incorporating a digital signal processor, is used to carry out real-time signal processing of the interferometer output to allow multipoint LDV to be implemented.

Measuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry
Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
متن کامل3-D Vibration and Motion Analysis of Microstructures
While originally developed for macrostructures, the full-field vibration mapping technique of laser scanning vibrometry can be applied successfully to microstructures by using microscope optics and high grade piezo scanners instead of camera lenses and galvo scanners. Polytec’s laser vibrometers operate on the Doppler principle, measuring back-scattered laser light from a vibrating structure to...
متن کاملPhase Modulation Detection and Vibrometry with Liquid Crystal Light Valve and Digital Holography
Self-adaptive interferometry allows the measurement of very small optical phase modulations even in noisy environments and with strongly distorted optical wavefronts. We review two techniques of self-adaptive interferometers based on liquid crystals spatial light modulators, one obtained by using an optically addressed light valve, the second one realized by adopting a digital holography CMOS-L...
متن کاملDiffractive beam splitter for laser Doppler velocimetry.
A miniaturized sensor head for the optical measurement of velocities of fluids based on laser Doppler velocimetry is demonstrated. Holographic optical elements mounted on a glass substrate are used for beam splitting and deflection. Volume holograms in dichromated gelatin exhibit good optical efficiency (75% transmission of a cascade of two holographic optical elements). With diffractive device...
متن کاملElectrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals using a Michelson interferometer
Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
