    Abstract: A colorimeter with multiple sensings of light to provide higher accuracy measurements of the primaries of a human-standard observer based color space is provided. This color space (target color space) must have the characteristic of two chromaticity coordinates and an achromatic primary like CIELAB, CIELUV or xyY in CIE 1931. The calibration of the device includes training with a set of calibration illuminants. Two sets of calibration-factors are determined. The first set of calibration factors yields intensity of primaries optimized with respect to chromaticity, the second set yields the optimized intensity of the achromatic primary. The combination of these sets of calibration factors enable the colorimeter to deliver values of that light with respect to three primaries of a human-standard-observer-based color space optimized with respect to chromaticity and the achromatic primary.

    Abstract translation: 提供了具有多种感光的比色计，以提供基于人标准观察者的颜色空间的基准的更高精度的测量。 该色彩空间（目标色彩空间）必须具有CIE 1931中的两个色度坐标和无色原色（如CIELAB，CIELUV或xyY）的特征。该设备的校准包括一组校准光源的训练。 确定两组校准因子。 第一组校准因子产生相对于色度优化的原色的强度，第二组产生无色初级的优化强度。 这些校准因子组的组合使得色度计相对于基于色度和无色原色优化的基于人 - 基准 - 观察者的颜色空间的三个基色传递该光的值。

    Abstract: A spectrally selective (e.g., color) target has been designed and fabricated for reflectance micro- and/or macro-imaging that utilizes microlens arrays and color mirrors. The color mirrors are optical interference coatings. The microlenses are designed and fabricated such that the light reflected from the color mirror is incident onto the detector. This system of microlenses and color mirrors allows the user to image different colored specular highlights. An infinite number of spectral reflectance profiles can be created with these color targets and used for spectral and colorimetric imaging applications. The targets are not limited to the visible region; they can also be designed to work in the ultraviolet and infrared wavelength regions.
