Abstract

A borescope is for optically inspecting gas turbines of aircraft engines. The borescope having an electronic image capture unit as a borescope objective at an end of a shaft, which is suitable for insertion into a borescope opening and configured for accurate positioning of the borescope objective relative to the borescope opening and through which data lines and supply lines for the image capture unit are guided. The image capture unit has: two spaced apart image capture sensors, recording cones of which overlap in a specified recording plane forming a recording region, in such a way that image data of the two image capture sensors are configured to be processed into 3-D data by way of triangulation.
