  • Intelligent light source
    Patent number: 6774893
    Abstract: Disclosed is a intelligent light source that is capable of providing a uniform illumination image across the surface of an illuminated object analyzed by an optical detector. This is accomplished by individually controlling each light-emitting element of a linear array of light elements. Calibration of the array is accomplished by sequentially illuminating each optical element of the source and building an array of normalized detected data. The matrix is then inverted and multiplied by a linear array of ones to generate the calibration data. The calibration data are then used to program a simple logic device that allows accurate digital control of the intensity of each individual light element.
