title: Generalized analysis of shearing interferometers as applied for gas dynamic studies.
abstract: Shearing interferometers are classified as instruments in which interference is produced between rays that are sheared in the test object by a small lateral distance. When applied to gas dynamic investigations these interferometers respond to changes of the gradient of the gas density in the test field. A generalized first-order analysis is described that applies to all arrangements of such shearing interferometers and emphasizes the application for the study of compressible gas flows.
