Title:
CONTROL METHOD FOR SPECTRO-COLORIMETER ILLUMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/051037
Kind Code:
A1
Abstract:
A control method for a spectro-colorimeter illumination system. The method comprises: S11: a synchronous control circuit controlling a first pulse drive circuit and a second pulse drive circuit to generate pulse drive signals at the same time, so as to drive the illumination of a full-spectrum LED and a multi-color LED, and the synchronous control circuit and a detector collection circuit driving the exposure of a detector; S12: when the pulse drive signals change from a high level to a low level, the synchronous control circuit and the detector collection circuit controlling the exposure of the detector to end, so as to obtain a spectral reflectivity curve under the current pulse drive signals; S13: repeating step S11 and step S12 multiple times, and increasing the time widths of the pulse drive signals upon each repetition, so as to obtain spectral reflectivity curves under the pulse drive signals at different times; and S14: fusing the spectral reflectivity curves under the pulse drive signals at different times, so as to obtain a complete spectral reflectivity curve of an object under test. By means of the control method for a spectro-colorimeter illumination system, a high signal-to-noise ratio reflectivity curve or a high-dynamic-range spectral reflectivity curve of an object can be effectively acquired.
