BOCA RATON, Fla., Dec. 19, 2016 — 2D Analysis SystemThe Atlas 2D Analysis System from Imperx Inc. combines the spatial resolution of a CCD camera with the spectral accuracy of a spectrometer to provide full characterizations of display quality in a short amount of time.

The spectrometer gathers all the light from within its field of view and provides a measurement of intensity as a function of wavelength. That data is processed to recover the CIE XYZ tristimulus values. Simultaneously, a co-aligned CCD camera acquires an red, green, blue (RGB image). A pre-aligned known region of the CCD image corresponds to the area sampled by the spectrometer. The CCD image is processed to recover the sum total of the RGB values for the identical region sampled by the spectrometer.

The ratio of the two measurements yields a conversion factor. To obtain XYZ values from regions outside the spectrometer’s field of view, one need only multiply the RGB values by the conversion factor to arrive at tristimulus values across the entire CCD.
