Abstract: Acoustic optical integrity detection system architectures and methods can be used to detect optical integrity of an optical component by detecting a discontinuity on and/or in the optical component (e.g., on the optical surface and/or within the bulk of the optical component). In some examples, integrity detection can be used to ensure safety compliance of an optical system, optionally including a laser. Acoustic integrity detection can utilize transducers (e.g., piezoelectric transducers) to transmit ultrasonic waves along an optical surface and/or through the thickness of an optical component. A discontinuity of the optical surface can interact with the transmitted wave causing attenuation, redirection and/or reflection of at least a portion of the transmitted wave. Portions of the transmitted wave energy after interaction with the discontinuity can be measured to determine discontinuity location, type, and/or severity.
