Abstract: A method for characterizing a primary radiant spectra of a projector includes projecting primary colors with a projector having a projector lamp and color filters. Measurements of each primary color are taken with a multi-band camera. Spectra of the color filters are estimated using the measurements from the multi-band camera. The primary radiant spectra of the projector are estimated using spectral data of the projector lamp and the estimated spectra of the color filters.

Abstract: A method and device for optical teledetection of compounds in a medium includes a detection measurement carried out by emitting into the medium, short pulses of light at least 3 nm wide, and detecting a part of the light back-scattered by the medium by means of a detection unit with temporal resolution. A reference measurement in which the light emitted or the light back-scattered is filtered by virtue of addressable filters, simulating the optical spectrum of the light at the working wavelengths of at least one given compound to be searched for. A comparison of the detection and reference measurements is made to deduce therefrom the possible presence of the compound or compound(s) searched for in the medium. The addressable filters are modified dynamically, and a series of reference measurements and corresponding comparisons are performed for a series of various compounds liable to be present in the medium.

Abstract: A miniaturized Holographic Fourier transform imaging spectrometer HFTIS, made from simple all-reflective components and with no moving parts, is provided. This HFTIS includes an all-reflective two beam interferometer, which provides two interfering beams; a two-dimensional detector array to detect the interference pattern created by the beams; a computing machine for correcting the distortions in the pattern and calculating the spectrum from the corrected interferogram. The same principle can be used to build spot spectrometers, line-scan imaging spectrometers (also called array spectrometers or line-scan hyperspectral cameras) as well as two-dimensional instantaneous imaging spectrometers (also called staring hyperspectral cameras). In all variants of HFTIS that can be built using this invention, the wave-signal collecting element can also be built of all-reflective components. Digital correction can be utilized to straighten the interference fringes and to compensate for the impact of used lenses and other refractive components, to produce correct spectra after Fourier Transformation.

The beam expander(s) anamorphically expand the reformatted light beam along the second axis into an expanded light beam. The dispersive element(s) disperse the expanded light beam along the second axis, resulting in a dispersed light beam. The light receiving element(s) receive the dispersed light beam.

Abstract: An object is to enable a change in a frequency for which an electric signal based on an optical signal is measured by a spectrum analyzer. An optical measurement device includes a first photoconductive switch that receives predetermined pulse light from a first laser light source, and outputs terahertz light having the same repetition frequency as the repetition frequency of the predetermined pulse light. The optical measurement device also includes a second photoconductive switch that receives the terahertz light and a sampling light pulse, and outputs a signal corresponding to a power of the terahertz light at a time point when the sampling light pulse is received. The optical measurement device further includes an RF spectrum analyzer that measures a magnitude of the signal corresponding to a measured frequency that changes over time, an optical coupler that outputs a simultaneous light pulse when the predetermined pulse light and the sampling light pulse are simultaneously input, a photo detector that converts the simultaneous light pulse into an electric signal as a trigger signal, and an optical delay circuit that delays the trigger signal.

Abstract: A mobile paint matching service employs at least one vehicle to perform on-site color matching. The vehicle is equipped with at least one portable spectrophotometer; a paint analysis system to determine recommended paint formulas; a plurality of spill-resistant containers, including containers holding a paint component (including paint bases and a variety of colorants) and others that are empty; and a paint mixer. A computerized scheduling system is used to schedule the vehicle for arrival at a plurality of job sites. At each job site, the color characteristics of painted surfaces are obtained using the portable spectrophotometer. Preferably, a recommended paint formula is determined using the paint analysis system based at least in part on averaging several different spectrophotometer readings. The paint mixer is used to mix selected paint components according to a specified paint formula. The customer can then purchase the paint to be used on the job directly at the job site after testing it to ensure that it matches.

Abstract: A label-free multiplexed sensing platform is based on light interaction with aperiodic photonic structures with an advantage of a broadband operation. Multiple-scattering-induced “fingerprinting” colorimetric signatures can be used as a transduction mechanism. Aperiodic sensing platforms can operate in the infrared to provide an overlap with spectral fingerprints of biological molecules. Miniaturized optical biosensors may be based on engineered colorimetric scattering signatures (structural color), sharp spectral features, non-uniform angular distributions of scattered light, and broadband manipulation of the local density of states in nano-textured scattering surfaces with deterministic aperiodic order. The biosensors can be fabricated in semiconductor, metal, low- and high-index dielectric platforms using standard nanofabrication techniques such as electron-beam lithography, ion-beam milling, etc, and can be replicated over large areas by standard nano-imprint lithography.
