    Abstract: A color sensor array includes a plurality of sensors. Each of the plurality of sensors has a width dimension and a length dimension that is elongated with respect to the width dimension. The length dimensions of the sensors are substantially equal to one another and parallel to an illumination plane. Each of the plurality of sensors includes a face defined by opposing first and second elongated sides and opposing first and second non-elongated sides. The first non-elongated sides of the plurality of sensors are aligned with one another along an axis that is substantially perpendicular to the illumination plane.

    Abstract: A first electrical path has a terminal, and a second electrical path has a terminal. First photovoltaic (PV) dies are electrically connected within the first electrical path. Each first PV die is adapted to convert light having a first wavelength range to electrical energy. Second PV dies are electrically connected within the second electrical path. Each second PV die is adapted to convert light having a second wavelength range different than the first wavelength range to electrical energy. A circuit is electrically connected between the terminals of the first and the second electrical paths to limit an absolute voltage difference between the terminals to no greater than a threshold voltage.

    Abstract: An optical device includes an aperture stop that limits an angular extent of light from an illuminated sample. A first lens is positioned between the aperture stop and a detector plane. A second lens is positioned between the first lens and the detector plane and is operable to map light from the aperture stop to the detector plane such that the light is averaged at the detector plane.

    Abstract: A color detector includes a light source, a filter, and a photodetector. The photodetector outputs a signal proportional to the amount of a predetermined color of light that passes through the corresponding filter. When used in an array, each filter may have different transmission characteristics, and each color signal may have a different magnitude and/or signal-to-noise ratio. This may be corrected for by adjusting the area of each of the photodetectors and corresponding filters. In other words, the areas if the photodetectors may be configured to equalize the color signal of a reference color and thereby maximize the signal-to-noise ratio of the color signals the sensor is intended to measure. The area of the photodetector may be based on a response curve of the photodetector as a function of wavelength, a response curve of the filter as a function of wavelength, and the amount of light as a function of wavelength generated by the light source, among other factors.
