reportActive / Technical Report | Accession Number: ADD000354 | Need Help?

Abstract:

The patent application discloses a method and apparatus for measuring the optical absorption coefficient in a sample. The absorption coefficient is determined by measuring the magnitude of an acoustic wave induced by an optical radiation pulse transversing a partially absorbing sample. Detection is accomplished by either attaching a stress or strain transducer to the solid or applying electrodes thereto and observing the electrical output signal.
