Document Type and Number:
Japanese Patent JPH10505407
Kind Code:
A
Abstract:
A method and apparatus for determining a first parameter(s) of an object is disclosed. The apparatus includes means for locating the object (101), in a measurement interaction volume(s) (150, 151, 152, 153), a light absorbing background (100), operatively associated with the measurement interaction volume(s), at least one light source (120), for passing a measurement light beams(s) through the measurement interaction volume(s) to interact with the object (101), to produce measurement outgoing light, the measurement light beam(s) comprising at least two spectrally different wavelengths of light, at least one detector (108, 109, 110), to detect the at least two measurement spectrally different outgoing light portions (105, 106, 107) and to general signals therefrom, whereby the signals are a function of the first parameter(s), the detector(s) (105, 106, 107) being operatively associated with the light source, means for filtering the measurement outgoing light (102, 103, 104) from the measurement interaction volume(s0 into at least two measurement spectrally different outgoing light portions (105, 106, 107), the means for filtering being operatively associated with the light source(s) and/or the at least one detector, and means for determining the first parameter(s) from the signals (125), the means for determining being operatively associated with the detector.
