Abstract:
An opto-electronic device utilizing a band of partially polarized polychromatic light for quantitative analysis of a specimen containing a target molecule, the device comprising:a polarizer for producing a segmented band of partially polarized polychromatic light from the band of partially polarized polychromatic light;a specimen cell adapted for receiving the specimen and for transporting the segmented band of partially polarized polychromatic light to the specimen;an RF source coupled to the specimen cell whereby the RF source causes particular changes of selected achiral molecules within the specimen;a polarizing analyzer optically coupled to the segmented band of partially polarized polychromatic light exiting the specimen; andcomparison means for comparing the segmented band of partially polarized polychromatic light before entering the specimen with the segmented band of partially polarized polychromatic light after exiting the specimen,wherein the target molecule changes ellipticity of the segmented band of partially polarized polychromatic light.
