Abstract: A handheld spectrometer can be configured with a visible aiming beam to allow the user to determine the measured region of the object. When the visible aiming beam comprises the spectrometer measurement beam, the spectrometer measurement beam comprises sufficient energy for the user to see the measurement beam illuminating the object. When the visible aiming beam comprises a separate beam, the visible aiming beam comprises sufficient energy for the user to see a portion of the aiming beam reflected from the object. The visible aiming beam and measurement beam can be arranged to at least partially overlap on the sample, such that the user has an indication of the area of the sample being measured.

Abstract: A method of calibrating an optical sensor may include acquiring a first characteristic for an external light source through a detector of an optical sensor while an internal light source of the optical sensor is turned off; driving the internal light source; acquiring a second characteristic for the internal light source and the external light source through the detector, based on driving the internal light source; and acquiring a reference characteristic of the internal light source, for calculation of an absorbance of an object, based on the first characteristic and the second characteristic.

Abstract: The color strength of a colored batch containing effect pigments can be measured and corrected using one or more non-uniformly weighted factors to determine, at a plurality of combinations of illumination angles and measurement angles, and at one or more wavelengths, the color and intensity of light reflected or absorbed by a coating film made from the batch in comparison to a reference color strength. Based on such comparison, let-downs or batches may be passed, rejected, mixed or otherwise dispersed. The composition of such let-downs or batches may also or instead be adjusted by adding non-effect pigments, effect pigments, binder, carrier, binder, or non-effect or effect pigments dispersed in either or both of a carrier and binder, in order to correct the let-down or batch color strength to within a desired tolerance of the reference color strength.

Abstract: The present invention provides a spectral imaging device characterized in that N images are captured with ambient light, and spectra can be obtained from the captured N images for spectral analysis. In particular, a filter device is employed to divide a spectral range of the ambient light into N spectral bands, and each capture corresponds to one spectral band.

Abstract: An interferometer system includes a measurement arm comprising a measurement dispersive optical system, a reference arm comprising a bulk diffuser object and a reference dispersive optical system, and an output system. The measurement dispersive optical system is positioned to direct measurement chromatic light towards a target, receive diverging chromatic measurement light from the target, and direct detected measurement light from the received diverging chromatic measurement light towards the output system. The reference dispersive optical system is positioned to direct reference chromatic light towards the bulk diffuser object, receive diverging chromatic reference light from the bulk diffuser object, and direct detected reference light from the received diverging chromatic reference light towards the output system. The output system is configured to determine at least one measured property of the target from the detected measurement light and the detected reference light.

Abstract: A measurement system includes an optical probe that has a reflective prism structure, an input system, and an output system. The reflective prism structure comprises at least two mirrored surfaces on opposing sides of an axis which extends in a direction towards a target. The input system is positioned to receive and direct source light towards one of the mirrored surfaces which is positioned to reflect the source light towards the target. The output system is positioned to receive and output converging light from reflected light that comprises measurement data related to the target. The reflected light is the source light reflected from the target via the other one of the mirrored surfaces and is without substantial overlap with the source light.

Abstract: In some examples, an apparatus may include a laser, a source fiber that delivers the laser radiation to an object, and a detector fiber that receives scattered laser radiation and illuminates a detector array with the scattered laser radiation to form speckles on the detector array. In some examples, the object may be directed illuminated by a laser. The detector array may include a plurality of detectors, and may be positioned to receive the scattered laser radiation from the end of the detector fiber. The distance between the detector array and the end of the detector fiber may be adjustable. A controller may be configured to receive detector data from the detector array, determine a time-dependent intensity autocorrelation function for each detector of a plurality of detectors, and determine an ensemble average autocorrelation function. The apparatus may provide information relating to dynamic processes within the object. Various other methods, systems, and computer-readable media are also disclosed.
