摘要 |
A sensor (10) for measuring reflective, transmissive, or self-luminous samples, comprises a plurality of light sources (18), where each of the light sources emit light of a substantially different wavelength band spaced in the visible spectrum; a reference channel photodetector (20); a sample channel photodectector (22); an optical cap (26) adapted to direct a first portion of the light emitted by each of the light sources to the reference channel photodetector (20); a reflector cone for directing a second portion of the light emitted by each of the light sources to the sample; and a receptor piece (36) for directing the diffuse portion of the light reflected from the sample to the sample channel photodetector (22). The sensor (10) is preferably incorporated into a hand-held "mouse" device, which includes an area on its top surface for seating an index finger of the human hand.
