Title: Method and apparatus for detecting photo-acoustic signal
Inventor: NAKADA TOSHIHIKO
IPC: G01N29/00
Filed: 1990-07-06
Abstract: PURPOSE:To decrease the halation of a photo-acoustic image and to make it possible to perform stable measurement at high resolution by obtaining a reverse filter for restoring the deterioration of the resolution of the photo-acoustic image based on the thermal impulse response of a sample, and making the filter act to the photo-acoustic image. CONSTITUTION:The parallel light emitted from an Ar laser 31 is modulated with intensity in a photo-acoustic modulating element 32. The intermittent light is condensed at a rear focal point position 81 with a lens 34. The luminous flux becomes collimated through a lens 36. The light is reflected from dichroic mirror 37 and condensed at a front focal-point position 82. An ultrasonic wave is generated by a thermal distortion wave generated by the photo-acoustic effect at the condensed spot of a sample 7. At the same time, minute displacement is generated on the surface of the sample 7. A Michelson interference optical system 140 detects the photo-acoustic effect generated in the inside of the sample in the two-dimensional directions of the sample and forms the two-dimensional photo-acoustic image. A computer 68 obtains a reverse filter for restoring the deterioration in resolution of the photo-acoustic image based on the thermal impulse response of the sample 7. The filter is made to act on the photo-acoustic image, and the resolution of the photo-acoustic image is improved. Thus, the internal information in the sample can be detected stably at high resolution.
