Title:Simultaneous determination of isopachic and isochromatic fringe patterns for dynamic loadings by holographic photoelasticity
Author(s):Holloway, D. C.
Subject(s):Isopachic Fringe Patterns
Isochromatic Fringe Patterns

Holographic Photoelasticity
Abstract:Two different holographic systems capable of providing separate but simultaneous isochromatic and isopachic fringe patterns for dynamic loadings are described. The development and assembly of a Q-switched ruby laser suitable for use as a light source in these systems is reported. One system involves the use of a quartz light rotator, and a double light pass through the specimen to separate the fringe patterns. The other system uses a partially aluminized specimen and a reflecting surface technique to isolate them. The theory is experimentally confirmed with static loadings, and numerous examples of dynamic events are shown.
