Abstract: A modulated light source emits light to illuminate a target surface which possesses a certain color and shade of color. Light that is reflected from the target surface is detected by an optical detector. The output from the optical detector is processed and fed back to the optical detector to compensate for any shift caused by ambient light, temperature or other external factors, and is differentially amplified to generate an output signal indicative of the color and shade of the target surface. The output signal from the differential amplifier is then demodulated by a synchronous detector to produce a substantially steady DC voltage that is indicative of the color or shade of color at the target surface. Where the target surface color shade is indicative of a certain measurable quantity or quality (such as an analyte concentration), the steady DC voltage is converted using a look-up table or mathematical formula into a corresponding quantity or quality measurement. In performing this conversion, compensation is made for any variations in modulated light source intensity due to temperature change.

Abstract: An alignment method is provided for a color scannerless range imaging system whereby the separate optical paths of colored texture and monochromatic range images may be precisely aligned. The range imaging system includes an illumination system for illuminating a scene with modulated infrared illumination, image forming optics for forming an image of the scene, optical means for forming first and second optical paths between the image forming optics and an image sensor, a transponder subject to modulation located in the first optical path for amplifying and converting infrared light to visible light to form a range image on the image sensor. The alignment method includes the steps of providing a target having alignment indicia that can be imaged in both infrared and visible regions of the spectrum, capturing an infrared image of the target using the first optical path, capturing a color image of the target using the second optical path, and adjusting at least one of the optical paths so that the captured images are coincident.

Abstract: An optical detection device for use in a color sorting apparatus for granular objects includes a CCD linear sensor. The CCD linear sensor comprises a plurality of light receiving elements arranged in one row each of which is capable of detecting red, green and blue wavelengths. The CCD linear sensor receives light from a granular object and a background which are irradiated by a red light source, a green light source and a blue light source. The red, green and blue light sources are switched over while the granular object is passing within an optical detection area. The CCD linear sensor receives light from the granular object in synchronization with the above switching operation of the light sources.

Abstract: Optical navigation upon grainy surfaces whose orientation is inclined at about 45° to the X and Y axes of the navigation mechanism is enhanced by: First, detect that a spatial filter in use is inappropriate for the orientation presently occurring, and; Second, employ a different and more appropriate spatial filter subsequent to such detection. Two spatial filters have been developed that are respectively effective about the 45° and 135° inclinations of the Standard filter. The shape of a correlation surface used in the navigation process is tested for the presence of a transverse ridge in the correlation surface. This generates control metrics whose filtered excursions are tracked by a control system that changes the spatial filter in use. The control system incorporates a time constant to prevent thrashing and excessive sensitivity to isolated random variations. The direction from which illumination arrives relative to the X and Y axes affects the range of angles (relative to, say, the Y axis) that a filter is effective, by changing the apparent size and proportions of the highlights and shadows that are the perceived features ultimately navigated upon. Stable operation of the control system can be enhanced by ensuring overlap of the filters' ranges, and can be promoted by dynamically altering the direction from which illumination reaches the navigation surface, so that it corresponds to, or varies in relation with, the filter in use.
