Abstract: In a multi-angle calorimeter having an illumination system that illuminates a sample surface and a plurality of light receiving systems that receive reflected light therefrom, an illumination system for orientation error detection is provided that illuminates the sample surface from substantially close direction to the normal of the sample surface. Actual measured reflectance factor is corrected based on the specific approximation function obtained from the measured reflectance factor and detected orientation error.

Abstract: The specification discloses a handheld color measurement instrument capable of reading both barcodes and sample colors. The instrument includes a single color measurement engine connected to a control capable of detecting and reading barcodes. When a barcode is detected, the control updates program and/or configuration information in accordance with information contained in the barcode. When a barcode is not detected, the control operates to read sample colors.

Abstract: A system includes a focal plane array (FPA), support structure, optical assembly, flexing structure, and drive actuator. The FPA includes multiple pixels. The FPA captures an image as image data during an integration time interval. The optical assembly is fixed to the support structure and forms an image of a scene at the FPA. The flexing structure is mechanically coupled to both the support structure and the FPA, and allows the FPA to move relative to the support structure. The actuator is mechanically coupled to the FPA, and drives the FPA to move relative to the support structure. Some FPA have all readout elements arranged in a first regular grid with constant spacing, while some detector elements are on that grid and other detector elements are on a different grid offset by less than the constant spacing to provide sub-pixel resolution.
