HoloVID
HoloVID is a tool originally developed for the holographic dimensional measurement of the internal isogrid webbing of the Delta Series of (launch vehicle) Space Craft skins by Mark Slater in 1981.
==History==
Delta Space Craft was produced by McDonnell Douglas Astronautics, until the line was purchased by Boeing Aircraft. Milled out of T6 Aluminum, on huge 40 foot by 20 foot horizontal mills, the inspection of the huge sheets took longer than the original manufacturing. It was estimated that a real time in-situ inspection device could seriously cut costs so an IRAD (Independent Research and Development ) budget was generated to solve the problem. Two solutions were worked simultaneously by Mark Slater, a photo-optical techniques utilizing Holographic lens, and an ultrasonic technique utilizing configurable micro-transducer multiplexed arrays.
A pair of HoloVids for simultaneous frontside and backside weld feedback, was later used at Martin Aerospace to inspect the long weld seams which hold the external fuel tanks of the Space Shuttle together. By controlling the Weld bead profile in real time as it was TIG generated, an optimum weight vs. performance ratio could be obtained, saving the launch engines from having to waste thrust energy, while guaranteeing the highest possible web strengths.
