Nondestructive testing by using long-wave infrared interferometric techniques with CO2 lasers and microbolometer arrays.
Igor Alexeenko,Jean-François Vandenrijt,Giancarlo Pedrini,Cédric Thizy,Birgit Vollheim,Wolfgang Osten,Marc Georges +6 more
TL;DR: Three different interferometric techniques are described, using a long-wave infrared radiation produced by a CO(2) laser and recorded on a microbolometer array, for nondestructive testing of electronic speckle pattern interferometry and digital shearography.
Journal ArticleDOI
Electronic speckle pattern interferometry and digital holographic interferometry with microbolometer arrays at 10.6 μm
TL;DR: Electronic speckle pattern interferometry and digital holographic interferometers are investigated at long infrared wavelengths and phase-shifting in-plane and out-of-plane electronic speckled patterns are demonstrated on rotation measurements of a solid object.
Journal ArticleDOI
Plastic recording media for holography at 10.6 μm
TL;DR: In this paper, a 1-W single mode cw CO2 laser was used for phase recording at a wavelength of 632.8 nm, which achieved a diffraction efficiency of 0.5%.

Cholesteric Structure-1 Optical Properties
TL;DR: The optical properties of cholesteryl benzoate have been studied in this paper, and the optical properties may be summarized as follows: 1) They are birefringent fluids.
Journal ArticleDOI
Liquid crystals in nondestructive testing.
TL;DR: An attempt has been made to give a complete picture of the cholesteric liquid crystal as applied to nondestructive testing, rather than to review the work actually being done in this field.
