This paper describes a prototype of an acousto-optic video spectrometer module that can be linked with rigid lens-type and flexible optical-fiber medical endoscopes. Examples are given of the resulting spectral images, demonstrating the main quality of the developed layout—minimization of spatiospectral distortions. This allows the device to be used in problems of photoluminescence diagnosis in medical applications to rapidly obtain both spectral images and undistorted complete spectra of any point of an image of an internal organ. The possibilities and prospects of this approach are analyzed.
