Laser-Ultrasonic Detection Of Subsurface Defects In Processed Metals

View page
US Patent:
20070234809, Oct 11, 2007
Filed:
Oct 4, 2005
Appl. No.:
11/242969
Inventors:
Marvin Klein - Pacific Palisades CA, US
Todd Sienicki - Los Angeles CA, US
International Classification:
G01N 29/04
G01N 21/88
US Classification:
073602000, 073627000, 073643000, 356237100, 356502000
Abstract:
Subsurface defects in a processed metal are detected by a laser-ultrasonic method involving generation of a surface acoustic wave at one location on the processed metal surface, and detection of a scattered acoustic wave at another location on the processed metal surface. The method can be used in-line to provide real time monitoring of laser cladding and other metal processing operations.

Chromomodal Dispersion Apparatus And Methods

US Patent:
20090021833, Jan 22, 2009
Filed:
Mar 5, 2007
Appl. No.:
11/682301
Inventors:
Bahram Jalali - Los Angeles CA, US
Todd Sienicki - Los Angeles CA, US
Assignee:
THE REGENTS OF THE UNIVERSITY OF CALIFORNIA - Oakland CA
International Classification:
G02B 5/18
US Classification:
359570
Abstract:
A system and method to chromomodally generate dispersion in light waves. The system and method may be used to control dispersive effects of an optical element such as a single-mode fiber. A light beam from the optical element is first collimated and then directed on to a spatially diffractive element where it is spatially dispersed into various chromatic frequency components. This frequency-separated light is then imparted onto a dispersion slope equalizer, and then passed into a highly multimode waveguide, where it is further dispersed. The light is then collected and focused back into an outgoing fiber-optic or other optical device.
