Abstract: A machine-vision system that provides changing and/or automatic adjustment of illumination angle, dispersion, intensity, and/or color of illumination. One such system includes a light source emitting polarized light, a machine-vision imager, an image processor operative to generate a quality parameter based on the image, and one or more of the means described above for selectively directing the light in a predetermined pattern based on its polarization and on the quality parameter of the image. Some embodiments include an imager, a controllable light source, first and second optical elements, that selectively direct light in first and second patterns, and a controller controlling the light characteristics using the first and second light patterns. One method includes setting one or more illumination parameters, illuminating the object based on the illumination parameters, obtaining an image, generating a quality parameter based on a region of interest, and iterating using different illumination parameters.

Abstract: An illumination source includes a plurality of LEDs, and an electrical circuit that selectively applies power from the DC voltage source to the LED units, wherein the illumination source is suitable for handheld portable operation. In some embodiments, the electrical circuit further includes a control circuit for driving the LEDs with electrical pulses at a frequency high enough that light produced has an appearance to a human user of being continuous rather than pulsed, the control circuit changing a pulse characteristic to adjust a proportion of light output having the first characteristic color spectrum output to that having the second characteristic color spectrum output. Some embodiments provide an illumination source including a housing including one or more LEDs; and a control circuit that selectively applies power from a source of electric power to the LEDs, thus controlling a light output color spectrum of the LEDs.
