Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) sources such as lamps, thermal sources, LED's, laser diodes, super-luminescent laser diodes, and super-continuum light sources for early detection of dental caries measure transmission and/or reflectance. In the SWIR wavelength range, solid, intact teeth may have a low reflectance or high transmission with very few spectral features while a carious region exhibits more scattering, so the reflectance increases in amplitude. The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools. The measurement device may communicate with a smart phone or tablet, which may transmit a related signal to the cloud, where additional value-added services are performed.

Abstract: The present invention provides a one-dimensional global rainbow measurement device and a measurement method. The measurement device comprises three parts, i.e., a laser emission unit, a signal collection unit and a signal processing unit. The laser emission unit is modulated to be a light sheet by a laser beam emitted by a laser, and configured to irradiate droplets in a spray field to generate rainbow signals. The signal collection unit is configured to separately image, by an optical system unit, the rainbow signals at measurement points of different height onto different row pixels of a CCD signal collector. The signal processing unit is configured to convert the received rainbow signals and process by a computer the rainbow signals in a form of data to obtain the measured values. The present invention can analyze gas-liquid phase flow fields during the injection, realize the online measurement of fuel atomization, spray and other processes, and can measure the refractive index, size, temperature and other parameters of the spray droplets in a real-time and non-contact manner.

Most hydro-carbons (gases, liquids and solids) exhibit spectral features in the SWIR, which may also coincide with atmospheric transmission windows (e.g., approximately 1.4-1.8 microns or 2-2.5 microns). Active remote sensing or hyper-spectral imaging systems may include a fiber-based super-continuum laser and a detection system and may reside on an aircraft, vehicle, handheld, or stationary platform. Super-continuum sources may emit light in the near-infrared or SWIR. An imaging spectrometer or a gas-filter correlation radiometer may be used to identify substances or materials such as oil spills, geology and mineralogy, vegetation, greenhouse gases, construction materials, plastics, explosives, fertilizers, paints, or drugs.

Abstract: An optical spectrum analyzer is implemented with a detector combined with a tunable filter mounted on a stage capable of 360-degree rotation at a constant velocity. Because of the constant rate of angular change, different portions of the input spectrum are detected at each increment of time as a function of filter position, which can be easily measured with an encoder for synchronization purposes. The unidirectional motion of the mirror permits operation at very high speeds with great mechanical reliability. The same improvements may be obtained using a diffraction grating or a prism, in which case the detector or an intervening mirror may be rotated instead of the grating or prism.
