Abstract: An apparatus and method are provided. In particular, at least one first electro-magnetic radiation may be provided to a sample and at least one second electro-magnetic radiation can be provided to a non-reflective reference. A frequency of the first and/or second radiations varies over time. An interference is detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. Alternatively, the first electro-magnetic radiation and/or second electro-magnetic radiation have a spectrum which changes over time. The spectrum may contain multiple frequencies at a particular time. In addition, it is possible to detect the interference signal between the third radiation and the fourth radiation in a first polarization state. Further, it may be preferable to detect a further interference signal between the third and fourth radiations in a second polarization state which is different from the first polarization state. The first and/or second electro-magnetic radiations may have a spectrum whose mean frequency changes substantially continuously over time at a tuning speed that is greater than 100 Tera Hertz per millisecond.

Abstract: A Raman microspectrometer system extends the optical reach and analysis range of an existing Raman microspectrometer to allow analysis and/or repair of an oversized sample. The Raman microspectrometer system includes an extender for extending the optical reach of the existing microspectrometer and a supplemental stage which extends the analysis range of the existing microspectrometer by providing travel capabilities for non-destructive analysis of an entire oversized sample. Such an arrangement decreases manufacturing costs associated with testing oversized samples such as mammography panels, enabling analysis and/or repair to be performed without destruction.

Abstract: The transmittance of a filter periodically varies with respect to the incident light frequency. Provided that fk is the sum of Fk and νk, or the difference obtained by subtracting Fk from νk, depending on the kth light source among multiple light sources, an incidence guide causes light from the plurality of light sources to be incident on the filter such that the propagation angle of light when light from the kth light source propagates through the interior of the filter equals θk obtained by computation using fk. The incidence guide causes light to be incident on the filter, taking fk to be the sum of νk and Fk for at least one of the light sources, and taking fk to be the difference between νk and Fk for at least one other of the light sources. A detector detects the intensity of transmitted light that transmits through the filter.

Abstract: A method is provided for testing a diffusely reflective liquid for colour strength, said liquid comprising particles in a carrier medium, e.g. white emulsion paint based on titanium dioxide. The method comprises measuring in situ a lightness parameter of the liquid, of the carrier medium and of the liquid diluted with amounts of carrier medium; and determining from said measurements a dilution parameter indicating the amount of carrier medium needed to produce a predetermined reduction in the lightness parameter of the liquid, said dilution parameter providing an indication of colour strength. The lightness parameter may be L* in the CIE L*, a*, b* colour space, and the test may be carried out using a diffuse reflection probe (10) configured to direct light from said probe (10) into the liquid and configured to collect a portion of the light from the probe (10) diffusely reflected by the paint for determining the lightness parameter. The results may be used for process control e.g. in emulsion paint manufacture.

Abstract: Modular systems can be used for optical analysis, including in-situ analysis, of stimulated liquids. An excitation module can include a radiation sources, e.g., a laser, LED, lamp, etc. A detection module can include one or more detectors configured to receive spectral and/or temporal information from a stimulated liquid. Such systems can be used to identify or measure optical emissions including fluorescence or scattering. The efficient excitation of liquid samples and collection of emissions from the samples provides substantial, up to four-fold increase in the emission signal over prior systems. In an example, emission measurements can be conducted in an isolated sample compartment, such as using interchangeable modules for discrete sampling, flow-through sampling, or sampling via fiber probe. The systems and methods described herein can be used to characterize natural aquatic environments, including assessments of phytoplankton pigments, biomass, structure, physiology, organic matter, and oil pollution.
