Apparatus For Generating X-Ray Holograms

View page
US Patent:
49559745, Sep 11, 1990
Filed:
Jan 18, 1990
Appl. No.:
7/470991
Inventors:
Charles K. Rhodes - Chicago IL
Keith Boyer - Los Alamos NM
Johndale C. Solem - Los Alamos NM
Waleed S. Haddad - Chicago IL
Assignee:
MCR Technology Corporation - Chicago IL
International Classification:
G03H 110
US Classification:
350 367
Abstract:
Apparatus for x-ray microholography of living biological materials. A Fourier transform holographic configuration is described as being most suitable for the 3-dimensional recording of the physical characteristics of biological specimens. The use of a spherical scatterer as a reference and a charge-coupled device two-dimensional detector array placed in the forward direction relative to the incident x-radiation for viewing electromagnetic radiation simultaneously scattered from both the specimen and the reference scatterer permits the ready reconstruction of the details of the specimen from the fringe pattern detected by the charge-coupled device. For example, by using a nickel reference scatter at 4. 5 nm, sufficient reference illumination is provided over a wide enough angle to allow similar resolution in both transverse and longitudinal directions. Both laser and synchrotron radiation sources are feasible for generating microholographs.

US Patent:
52145816, May 25, 1993
Filed:
Jan 17, 1990
Appl. No.:
7/466042
Inventors:
Charles K. Rhodes - Chicago IL
Keith Boyer - Los Alamos NM
Johndale C. Solem - Los Alamos NM
Waleed S. Haddad - Chicago IL
International Classification:
G06F 1500
US Classification:
36441319
Abstract:
Apparatus for x-ray microholography of living biological materials. A Fourier transform holographic configuration is described as being most suitable for the 3-dimensional recording of the physical characteristics of biological specimens. The use of a spherical scatterer as a reference and a charge-coupled device two-dimensional detector array placed in the forward direction relative to the incident x-radiation for viewing electromagnetic radiation simultaneously scattered from both the specimen and the reference scatterer permits the ready reconstruction of the details of the specimen from the fringe pattern detected by the charge-coupled device. Both laser and synchrotron radiation sources are feasible for generating microholographs. Operation in the water window (2. 4 to 4. 5 nm) should provide maximum contrast for features of the specimen and spatial resolution on the order of the wavelength of x-radiation should be possible in all three dimensions, which is sufficient for the visualization of many biological features.
