A system and method for measurement of the polarization of fluorescence. A laser source provides a collimated linearly polarized beam of high intensity and small cross-section. A relatively small number of optical components are employed to minimize spurious fluorescence and spurious polarization which usually occurs from most optical materials. A photodetector provides an electrical signal in response to and representative of fluorescence polarization and is processed to directly produce first and second signals representing the difference and sum components of the polarization equation, the ratio of these components being directly provided without need for division computation. |
