Abstract:

Subject of study. Device for stereoscopic visualization of objects in various spectral ranges. Aim of study. Development of a stereoscopic spectrometer layout based on a tunable acousto-optical filter. Method. An original symmetric scheme for filtering two light beams (stereo pairs) in one acousto-optical cell with beam separation in the azimuthal plane is implemented. Main results. A prototype device has been assembled in the form of an experimental stand containing an acousto-optical filter, a prism-lens optical system and a video camera with a lens. Images of test objects demonstrating the spectral sensitivity of the device were obtained. Practical significance. The layout of the developed stereo spectrometer, capable of simultaneously receiving spatial and spectral information about an object, can become a prototype device for solving various machine vision problems, including in an out-of-laboratory environment.
