Abstract
Hologram apparatus for detecting flaws has a photographic station for supporting a photosensitive medium. The photographic station together with the photosensitive medium forms a developing chamber with a transparent face having a depth in the range of from about 0.005' to about 0.125, preferably from about 0.005' to about 0.125'. The developing chamber has a periphery with a contour which always changes at an angle greater than about 115.degree. and is preferably circular. Associated hydraulic equipment supplies and removes fluid from the developing chamber. A laser supplies coherent light for the article to be tested for reflection to the photographic station. A reference beam is directed to the photographic station. For use in inspecting pipe in the field, the apparatus advantageously has a housing and a pair of saddles each having different diameter pipe receiving portions and a strap securing system. The photographic station can develop the photosensitive medium in situ and may be used in any spatial orientation. The invention also comprises the photographic station per se without the laser.
