Optical Metrology in the Transportation Industry
Optical metrology has experienced an escalation in research, development, and applications within the transportation industry. With advances in digital imaging devices, evolution in computer technologies, including algorithms and software, and development of novel loading and stressing schemes, it has become an indispensable technique that enables the transportation industry to develop, design,...
متن کاملNew Millennium Interferometer Laser Metrology Testbed New Millennium Interferometer Laser Metrology Testbed by
The New Millennium Interferometer Laser Metrology Testbed is a technology demonstration for a key component of the New Millennium Interferometer (NMI). For the success of NMI, NASA's proposed mission to fly a space-based interferometer, control of its position must be very precise. Laser Metrology is a powerful tool that uses interferometry to make hyper-fine distance measurements. The proposal...
متن کاملOcular microtremor measurement using laser-speckle metrology.
We describe a novel, noninvasive measurement approach for recording a small involuntary tremor of the eye known as ocular microtremor. The method is based on measuring out-of-plane angular displacements of a target by using laser-speckle correlation of images recorded in the Fourier plane of a lens. The system has a dynamic range of 4 to 5000 μrad, resolution of 4 μrad, and a bandwidth of 250 H...
متن کاملLaser Scanning and Photogrammetry: 21 Century Metrology
New technologies often turn heads the first time they appear. Laser scanning is one such new technique, which has impressed many users by the ability of point clouds to provide an understanding of complex subjects. Laser scanning holds obvious benefits to architectural recording, however such technology should not be used with blind faith as a solution to all problems. As with all new technolog...
متن کاملMetrology guided laser micromachining of SiC for mirrors
Silicon carbide mirrors are sought for a variety of aerospace applications. While optical polishing techniques are straight forward for flat and spherical surfaces, material removal rates for this hard, brittle material are too low for affordable processing of conventionally machined, ground, or as-produced surfaces. The problem is more severe for aspheres. This paper reports on the use of pico...
