Abstract: There is provided a measurement apparatus including a light source unit configured to emit pulsed laser light used for pump light and Stokes light that excite predetermined molecular vibration of a measurement sample and for probe light that is intensity-modulated with a predetermined reference frequency and that has a same wavelength as the pump light or the Stokes light, a pulse control unit configured to cause time delay of the probe light generated by the light source unit and then to guide the pump light, the Stokes light, and the time-delayed probe light to the measurement sample, and a detection unit configured to detect transmitted light transmitted through the measurement sample or reflected light from the measurement sample. A relaxation time of the molecular vibration of the measurement sample is measured using time-resolved stimulated Raman gain spectroscopic measurement or time-resolved stimulated Raman loss spectroscopic measurement of the measurement sample.

Abstract: A programmable, many-band spectral imager based on addressable spatial light modulators (ASLMs), such as micro-mirror-, micro-shutter- or liquid-crystal arrays, is described. Capable of collecting at once, without scanning, a complete two-dimensional spatial image with ASLM spectral processing applied simultaneously to the entire image, the invention employs optical assemblies wherein light from all image points is forced to impinge at the same angle onto the dispersing element, eliminating interplay between spatial position and wavelength. This is achieved, as examples, using telecentric optics to image light at the required constant angle, or with micro-optical array structures, such as micro-lens- or capillary arrays, that aim the light on a pixel-by-pixel basis. Light of a given wavelength then emerges from the disperser at the same angle for all image points, is collected at a unique location for simultaneous manipulation by the ASLM, then recombined with other wavelengths to form a final spectrally-processed image.

Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the pass band of the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.
