Abstract: The present invention provides systems and methods for analyzing the excitation spectra of fluorescent particles in a flowing stream. The system uses a white light laser and color separation optics to provide a spatially-distributed, continuous color-spectrum excitation light system that is used to illuminate a region of a flowing stream. A particle that passes through the detection region traverses the full dispersed spectrum of excitation light, and the fluorescence emissions from the particle are continuously measured as it passes through the detection region. The measured fluorescence emissions at each wavelength of excitation light, which changes through full spectrum of the excitation light as the particle passes through the detection region, provides the excitation spectrum of the particle.

Abstract: An optical chromatic dispersion compensator (60) betters optical communication system performance. The dispersion compensator (60) includes a collimating means (61) that receives a spatially diverging beam of light from an end of an optical fiber (30). The collimating means (61) converts the spatially diverging beam into a mainly collimated beam that is emitted therefrom. An optical phaser (62) receives the mainly collimated beam from the collimating means (61) through an entrance window (63), and angularly disperses the beam in a banded pattern that is emitted from the optical phaser (61). A light-returning means (66) receives the angularly dispersed light and reflects it back through the optical phaser (62) to exit the optical phaser near the entrance window (63) thereof.
