FIELD: physics; X-ray inspection.
SUBSTANCE: additionally, the third semi-transparent mirror is introduced, located at the optical axis of the TV camera lens, between the lens and the first mirror; the second lens, the optical axis of which coincides with the axis running through the intersection point of the third mirror and the optical axis of the pancratic lens of the TV camera, normal to this axis; the second measuring scale for the measurement of the size of flaws in the object plane, located in the focal plane of the second lens so that the scale can be rotated relative to its optical axis; the second light source for the illumination of this scale.
EFFECT: measurement of size of flaws on object surface.
