The demands for greater product quality and product reliability has created a need for better techniques of nondestructive evaluation. Each of the available techniques including ultrasonic, acoustical emissions, radiography, thermography, magnetic particles, eddy current, dye penetrant, and optical methods such as holography and shearography has its unique advantages and disadvantages. The selection of one technique depends on the particular objective of the evaluation. When selecting a technique, it is important to have a sound knowledge of the capabilities as well as limitations of each technique. This paper will give a thorough review of two major optical methods of nondestructive testing: holography and shearography.
