The problem of recording of spectral images and identifying the reflection spectra of hard-to-reach objects is considered. To solve this problem, an acousto-optic spectral imaging module compatible with conventional endoscopic probes is developed and manufactured. The optical scheme and construction of the device are described. The device can be used for nondestructive testing of different engineering objects.



The development of the AOTF-based endoscopic spectral imaging system was performed within Fundamental Scientific Research Program of RAS (project no. 0069-2016-0005). Experimental research was supported by the Russian Foundation for Basic Research, project no. 16-07-00393.
