High-speed photography at rates of up to 20,000 images per second was used to measure these properties in thermal battery igniters and also the ignition of thermal battery itself. By synchronizing a copper vapor laser to the high-speed camera, laser-illuminated images recorded details of the performance of a component. Output characteristics of several types of hermetically-sealed igniters using a TiH{chi}/KCIO{sub 4} pyrotechnic blend were measured as a function of the particle size of the pyrotechnic fuel and the closure disc thickness. The igniters were filmed under both ambient (i.e., unconfined) and confined conditions. Recently, the function of the igniter in a cut-away section of a ``mock`` thermal battery has been filmed. Partial details of these films are discussed in this paper, and selected examples of the films will be displayed via video tape during the presentation of the paper.
