ABSTRACT:
A high-speed optical sensing device is provided in the present invention. The high-speed optical sensing device has an optical detector, a lens set, and a beam splitter. The optical detector is utilized for detecting luminous intensity. The lens set is utilized for concentrating light beams toward a color analyzer. The beam splitter is aligned to the illuminating device to be detected and is utilized to separate the light beam generated by the illuminating device to the optical detector and the lens set simultaneously.
