Non-contact optical system for detecting ultrasound waves from a surface

Title: Non-contact optical system for detecting ultrasound waves from a surface

Abstract

A system for detecting pressure, acoustic or ultrasound waves within an entity having a surface including the steps of attaching a signal converting material to the surface. The waves are generated by direct ejection from the surface, generation via energy deposition on the surface, generated spontaneously or, generated by directing light energy to the light absorbing target. The absorbing target subsequently generates acoustic pressure waves. The acoustic waves propagate to the surface of the entity and the signal converting material, wherein the acoustic pressure waves create vibrations in the signal converting material; and detecting the waves in the signal converting material with an optical detection system. Information about the absorbing target is obtained by the absorbing target reflecting the waves. The signal converting material can be a gel-like material containing optical elements, a multi-layer patch, or other material.

Non-contact feature detection using ultrasonic Lamb waves

Patent Sinha, Dipen N [Los Alamos, NM]

Apparatus and method for non-contact ultrasonic detection of features on or within the walls of hollow pipes are described. An air-coupled, high-power ultrasonic transducer for generating guided waves in the pipe wall, and a high-sensitivity, air-coupled transducer for detecting these waves, are disposed at a distance apart and at chosen angle with respect to the surface of the pipe, either inside of or outside of the pipe. Measurements may be made in reflection or transmission modes depending on the relative position of the transducers and the pipe. Data are taken by sweeping the frequency of the incident ultrasonic waves, usingmore »« less

System and method of reducing motion-induced noise in the optical detection of an ultrasound signal in a moving body of material

Patent Habeger, Jr., Charles C. (Smyrna, GA); LaFond, Emmanuel F [Atlanta, GA]; Brodeur, Pierre [Smyrna, GA]; ...

The present invention provides a system and method to reduce motion-induced noise in the detection of ultrasonic signals in a moving sheet or body of material. An ultrasonic signal is generated in a sheet of material and a detection laser beam is moved along the surface of the material. By moving the detection laser in the same direction as the direction of movement of the sheet of material the amount of noise induced in the detection of the ultrasonic signal is reduced. The scanner is moved at approximately the same speed as the moving material. The system and method maymore »« less

System and method for laser-based, non-evaporative repair of damage sites in the surfaces of fused silica optics

Patent Adams, John J.; Bolourchi, Masoud; Bude, Jeffrey D.; ...

The present disclosure relates to a system for repairing a damage site on a surface of an optical material. The system may have an Infrared (IR) laser which generates a laser beam having a predetermined wavelength, with a predetermined beam power, and such that the laser beam is focused to a predetermined full width ("F/W") 1/e.sup.2 diameter spot on the damage site. The IR laser may be controlled to maintain the focused IR laser beam on the damage site for a predetermined exposure period corresponding to a predetermined acceptable level of downstream intensification. The laser beam may heat the damagemore »« less

Non-contact fluid characterization in containers using ultrasonic waves

Patent Sinha, Dipen N [Los Alamos, NM]

Apparatus and method for non-contact (stand-off) ultrasonic determination of certain characteristics of fluids in containers or pipes are described. A combination of swept frequency acoustic interferometry (SFAI), wide-bandwidth, air-coupled acoustic transducers, narrowband frequency data acquisition, and data conversion from the frequency domain to the time domain, if required, permits meaningful information to be extracted from such fluids.
