Paper Abstract

The design of a panoramic viewing system and its application to cavity inspection and measurement are discussed, along with the general properties of a special panoramic annular lens (PAL). Various examples are described, showing how the PAL can be used for simple inspection or for precision contouring of interior walls of cavities using techniques such as moire, holointerferometry, and Electronic Speckle Pattern Interferometry (ESPI).
