ABSTRACT:
A method for calibrating an illumination system is disclosed herein. The illumination system comprises at least one light emitter and at least one color sensor. The method comprises emitting a first wavelength of light from the a light emitter and measuring the color of light emitted by the light emitter using the color sensors. A second wavelength of light is emitted from the a light emitter and the color of light emitted by the light emitter is measured using the color sensors. The shift in color space based on the measurements is calculated. At least one calibration matrix based on the shift in colors space is calculated.
