A method for identifying a result of a test carried out from a fluidic sample, the fluidic sample being contained in a translucent container, the container being positioned on an area of interest of the container and opposite a dedicated area of the support. Ranges of reference colorimetric values and geometric references are printed on the support which also includes calibration colorimetric values printed in the at least one color calibration area.

A spectrometer includes a spectrogram, digital camera and signal processing to compensate for limits of system spatial resolution, spatial distortions and lack of precision spatial registration, limited dynamic range, The spectrogram is captured by a digital camera, and the corresponding image is converted to a wavelength and magnitude with mitigation of optical point spread function and potential magnitude clipping due to over-exposure. The clipped portions of the signal are reconstructed using tangential adjacent point spread functions as a reference or adjacent channel ratios as reference. Multichannel camera detectors having unique response magnitude ratios per wavelength are exploited to make associated direct mappings, thereby making improvements in wavelength resolution and accuracy to up to at least one to two orders of magnitude.

A printing apparatus includes a control unit configured to generate color chart data, a transport unit configured to intermittently transport a medium, a printing unit configured to print a colorimetric patches on a processing unit region, a drying unit configured to dry the processing unit region, and a colorimetric unit configured to measure a color of the colorimetric patches in the processing unit region subjected to the drying, wherein the control unit is configured to acquire, based on a printing setting, a drying holding time during which the processing unit region is held at the drying unit, calculate a color-measurable patch number which is measurable by the colorimetric unit within the drying holding time, and generate the color chart data for printing a number of the colorimetric patches in the processing unit region, the number being less than or equal to the color-measurable patch number.

A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.

An illumination device and method is provided herein for calibrating individual LEDs in the illumination device, so as to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.

A process for analyzing a fracture or crack surface of a TiAl turbomachine part is provided. The process includes: marking on the surface the position and the orientation of cleavage facets, so as to identify a region of fracture or crack initiation and to determine the direction of propagation of this fracture or crack; examining the surface and detecting the regions with the presence of equiaxed grains and/or lamellar grains, so as to evaluate the temperature at which the fracture or crack has taken place, and comparing the heat tintings of the surface with those of samples from a heat tinting color chart so as to evaluate the speed of propagation of the fracture or crack.

A computer implemented method. The method includes generating, using a processor, a multi-dimensional object from a plurality of data obtained from a spectrophotometric measurement of a target coating. The method also includes calculating, using the processor, at least one geometric property of the multi-dimensional object. The method further includes correlating, using the processor, the at least one value with a plurality of known values to identify at least one pigment effect in the target coating, and outputting, using the processor, the at least one pigment effect.
