High-resolution and broadband all-fiber spectrometers
The development of optical fibers has revolutionized telecommunications by enabling long-distance broadband transmission with minimal loss. In turn, the ubiquity of high-quality, low-cost fibers has enabled a number of additional applications, including fiber sensors, fiber lasers, and imaging fiber bundles. Recently, we showed that a multimode optical fiber can also function as a spectrometer ...
متن کاملHigh-speed high-accuracy three- dimensional shape measurement using digital binary defocusing method versus sinusoidal method
This paper presents our research findings on high-speed high-accuracy three-dimensional shape measurement using digital light processing (DLP) technologies. In particular, we compare two different sinusoidal fringe generation techniques using the DLP projection devices: direct projection of computer-generated 8-bit sinusoidal patterns (a.k.a., the sinusoidal method), and the creation of sinusoi...
متن کاملA broadband high spectral brightness fiber-based two-photon source.
After characterizing the Raman scattering in a fused silica polarization-maintaining microstructure optical fiber, we built a fiber-based two-photon light source of high spectral brightness, broad spectral range, and very low noise background at room temperature. The resulting bright low-noise two-photon light can be used for a number of quantum information applications.
متن کاملNon-contact Deflection Measurement at High Speed
ABSTRACT: Traditional stationary or low speed deflection measurements become problematic on roads with high traffic densities. Traffic safety is decreased when survey vehicles like low speed deflectographs or stationary falling weight devices carry out measurements on highway networks. This paper describes how the Greenwood High Speed Deflectograph applies Laser Doppler Technology to provide in...
متن کاملAn All Fiber White Light Interferometric Absolute Temperature Measurement System
Recently the author of this article proposed a new signal processing algorithm for an all fiber white light interferometer. In this article, an all fiber white light interferometric absolute temperature measurement system is presented using the previously proposed signal processing algorithm. Stability and absolute temperature measurement were demonstrated. These two tests demonstrated the feas...
