Disclosed is an optical micro-spectrometry system including an optical microscope, a spectrometry system and an optical system adapted to direct an excitation light beam on the sample through the at least one microscope objective and to collect a Raman or PL light beam from a sample. The optical micro-spectrometry system includes an imaging system configured for acquiring a first image and a second image of the sample, by reflection or transmission of an illumination beam from a sample surface, the first image having a large field of view and the second image having a small field of view, a processing system configured for determining an area in the first image corresponding to the second image, a display system configured for displaying the first image, the second image, and a third image representing the area in overlay on the first image.

Micro-spectrometry measurement method and system

Methods, devices, controllers and systems for color calibration of displays, non-volatile (non-transient) memory, controllers, display devices or display systems including a color calibration transform, operation of such controllers, display devices or systems and software for color calibration of a display are described are described that make use of a color transform having a distribution of color points across a full display gamut (hence optionally preserving full contrast and color saturation in the calibrated display) in an at least substantially perceptually uniform manner suitable for use as a color display calibration adapted for medical applications. A perceptually uniform spread of color points can be in terms of a distance metric such as deltaE2000 for color or JND for gray.

Perceptually optimised color calibration method and system

The invention relates to a method for reducing imaging artifacts during a frame-changeover from a current frame to a following frame displayed by a display device comprising a plurality of pixels, wherein the artifacts are reduced by overdriving at least one control signal for controlling the pixel intensity of the related pixel during the frame-changeover, wherein the overdrive is carried out in dependence of the magnitude of an intensity step between a designated start intensity value of the pixel within the current frame and a designated target intensity value of the pixel within the following frame.
