| 摘要 |
A color meter including: a plurality of light sources (30, 32, 34) which generate a plurality of preselected, respective, bandwidths of light; a control unit (26) operative for activating said light sources (30, 32, 34) in accordance with a preselected sequence; an optical medium (18) associated with said light sources (30, 32, 34) which carries light generated by said light sources (30, 32, 34) along a preselected projection path onto a preselected sample region (12), and carries light reflected from said sample region (12) along a reflection path which at least partially overlaps said projection path; and an optical sensor (28) associated with said optical medium (18) which provides an output responsive to the intensity of light reflected from said sample region (12).
