PHOTONIC MOLECULAR PROBE

摘要

An opto-electronic device utilizes a band of polychromatic light for quantitative analysis of a target molecule within a mixed specimen. A movable polarizes produces a segmented band of partially polarized polychromatic light firm the band of partially polarized polychromatic light. A specimen cell adapted for receiving the mix ed specimen transports the segmented band of partially polarized polychromatic light to the mixed specimen. A movable polarizing analyzer is optically coupled to the segmente d band of partially polarized polychromatic light exiting the mixed specimen. The segmented band of partially polarized polychromatic light before entering the mixed specimen i s compared with the segmented band of partially polarized polychromatic light after exiting the mixed specimen. The movable polarizer is synchronized with the movable polarizing analyzer. Additionally a frequency filter can be optically coupled to the movable polarizer, where the frequency filter produces a beam of single frequency elliptically polarized light from the band of partially polarized polychromatic light such that the segmented band of partially polarized polychromatic light is a segmented band of elliptically polarized light.
