Ultraviolet-visible acousto-optic tunable spectroscopic imager for medical diagnosis.

An ultraviolet to visible acousto-optic tunable filter was used to measure native fluorescence images from in vitro breast tissues at different wavelengths. Pseudocolor maps based on fluorescence images at two wavelengths were used to separate normal and abnormal regions in human breast tissues in vitro, providing diagnostic information. © 1998 Society of Photo-Optical Instrumentation Engineers.
