International Classification:
H04N 7/18
US Classification:
348125
Abstract:
Systems and methods for inspecting capsules and capsule fill tube assemblies (CTFA) are provided. The 3-D Surface Mapping System (SMS) is used to generate 3-D surface information of each CFTA used in fusion ignition experiments. The CFTA includes a hollow capsule and an attached fill tube. This fragile CFTA's surface is inspected by using an optical microscope to gain volumetric information of particulates and surface defects at a sub-micrometer scale resolution. In order to completely inspect the entire surface of the CFTA the mechanical system requires multiple linear and rotational stages in addition to end effectors to safely hold the CFTA. By combining the optical microscope along with the mechanical system, a three-dimensional replication of the surface is generated providing information on surface feature defects and particulate sizes.
Atomic Vapor Laser Isotope Separation Of Lead-210 Isotope
US Patent:

Filed:
May 27, 1997

International Classification:
B01D 500
US Classification:
2041572
Abstract:
An isotopically selective laser process and apparatus for removal of Pb-210 from natural lead that involves a one-photon near-resonant, two-photon resonant excitation of one or more Rydberg levels, followed by field ionization and then electrostatic extraction. The wavelength to the near-resonant intermediate state is counter propagated with respect to the second wavelength required to populate the final Rydberg state. This scheme takes advantage of the large first excited state cross section, and only modest laser fluences are required. The non-resonant process helps to avoid two problems: first, stimulated Raman Gain due to the nearby F=3/2 hyperfine component of Pb-207 and, second, direct absorption of the first transition process light by Pb-207.
Heterodyne Laser Instantaneous Frequency Measurement System
US Patent:
4798467, Jan 17, 1989
Filed:
Sep 24, 1986
Appl. No.:
6/911023
Inventors:
Richard W. Wyeth - Livermore CA
Michael A. Johnson - Pleasanton CA
Michael A. Globig - Livermore CA
Michael A. Johnson - Pleasanton CA
Michael A. Globig - Livermore CA
Assignee:
The United States Department of Energy - Washington DC
International Classification:
G01B 902
US Classification:
356349
Abstract:
A heterodyne laser instantaneous frequency measurement system is disclosed. The system utilizes heterodyning of a pulsed laser beam with a continuous wave laser beam to form a beat signal. The beat signal is processed by a controller or computer which determines both the average frequency of the laser pulse and any changes or chirp of th frequency during the pulse.

International Classification:
G01B 902
US Classification:
356349
Abstract:
The heterodyne laser diagnostic system includes, in one embodiment, an average power pulsed laser optical spectrum analyzer for determining the average power of the pulsed laser. In another embodiment, the system includes a pulsed laser instantaneous optical frequency measurement for determining the instantaneous optical frequency of the pulsed laser.
