Abstract:
Provided is a spectroscope that can be manufactured easily, can be reduced in size, and can provide high wavelength resolution of a specific spectral band. Specifically, provided is a spectroscope with a diffraction grating 331 that deflects and separates incident light in different directions depending on to an element of the incident light, at least one optical element 332a, diffusing a light that has passed through this diffraction grating 331 and has entered the optical element 332a, a line sensor 333, which receives the light that has passed through the optical element 332a, thereby only light that has a specific deflection angle within a specific range of wavelengths from among all the light that entered said optical element 332a is selectively expanded and received.

Abstract:
A light fixture, using one or more solid state light emitting elements utilizes a diffusely reflect chamber to provide a virtual source of uniform output light, at an aperture or at a downstream optical processing element of the system. Systems disclosed herein also include a detector, which detects electromagnetic energy from the area intended to be illuminated by the system, of a wavelength absent from a spectrum of the combined light system output. A system controller is responsive to the signal from the detector. The controller typically may control one or more aspects of operation of the solid state light emitter(s), such as system ON-OFF state or system output intensity or color. Examples are also discussed that use the detection signal for other purposes, e.g. to capture data that may be carried on electromagnetic energy of the wavelength sensed by the detector.
Abstract:
A hand held measurement apparatus and method for in situ optical analysis of a specific display screen or viewing box and associated ambient light environment is disclosed. The apparatus uses a plurality of input collector optics and a plurality of optical filter/photodetectors as a device to separate the light output of an individual monitor screen, display screen, or viewing box and associated ambient light environment into key optical component intensities, the analysis of which are used to optimize the probability for a correct diagnosis by a qualified viewer/analyst. The optical signals are converted into digital electrical signals, processed, and compared to previously stored information of the specific viewing display and the viewing display environment in order to determine if the combination of viewing device and viewing environment is either GO (acceptable, in compliance) or NO GO (not acceptable, non-compliant) according to industry standards or approved procedures.
Abstract:
A light measuring device is disclosed which can take in light from different portions of a plane light source efficiently to carry out measurement. The light measuring device for measuring light from a plane light source includes a spatial division device configured to carry out operation for successively taking in light from different portions of the plane light source. An optical condensing device condenses the light from the different portions of the plane light source taken in by the operation of the spatial division device. A detector receives the light condensed by the optical condensing device and outputs a signal corresponding to the received light.
Abstract:
A particle detection and classification system is disclosed. The system determines the size of measured particles by measuring light scattered by the particles. The system simultaneously determines whether measured particles are biological or non-biological by measuring fluorescent light from the particles. The system uses a parabolic reflector, and optionally, a spherical reflector to collect fluorescence light.

Abstract:
A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated color of a structure is also provided.
Abstract:
A high-density channels detecting device for detecting a sample is provided. The high density detecting-device has a light source for emitting a light beam, a collimator, a beam splitter, and a high-density channels imaging device. The collimator arranged on the beam path is used for collimating the emitted light beam. The beam splitter reflects the light beam incident from the collimator to the sample, and the light beam reflected by the sample passes through the beam splitter. The imaging device receives the light beam passing through the beam splitter, and has a light collector and a multi-channel kernel module for receiving the light beam from the light collector. By using the light collector, the light beam incident to the kernel module is parallel to the optical axis of the kernel module.
