Abstract
The present invention provides for novel devices for the detection of acoustic or ultrasonic signals within a fluid by way of selective delaminating of portions of a multiplicity of laminar films, the laminar films providing high reflectance over select wavelengths and optical transparency to others, wherein delamination results in the creation of optically resonant chambers which when interrogated with EM radiation may be used to provide highly sensitive detection of the acoustic or ultrasonic signals.
