Title: Innovations of Johndale C Solem
Introduction
Johndale C Solem is a notable inventor based in Los Alamos, NM (US). He has made significant contributions to the field of x-ray holography, particularly in the study of biological materials. With a total of 2 patents, his work has advanced the understanding and visualization of microscopic physical details in biological specimens.
Latest Patents
Solem's latest patents include a "Method for object reconstruction from x-ray holograms" and "Apparatus for x-ray microholography of living biological materials." These patents describe a Fourier transform holographic configuration that is particularly suitable for the three-dimensional recording of the physical characteristics of biological specimens. The innovative use of a spherical scatterer as a reference, along with a charge-coupled device two-dimensional detector array, allows for the simultaneous viewing of electromagnetic radiation scattered from both the specimen and the reference scatterer. This setup facilitates the reconstruction of detailed images from the fringe patterns detected by the charge-coupled device.
Both laser and synchrotron radiation sources can be utilized for generating microholographs. Operating in the water window (2.4 to 4.5 nm) provides maximum contrast for specimen features, and spatial resolution on the order of the wavelength of x-radiation is achievable in all three dimensions. This capability is sufficient for visualizing many biological features. Furthermore, a computational procedure has been developed to correct for misalignments that may arise from inexact knowledge of the relative positions of the spherical reference scatterer and the sample under investigation.
