Fiber optic matrix coding method and apparatus for radiation image amplifier

Details

Inventors: McIntyre, John A.;
Assignee:
Primary Examiner: Nelms; David C.
Assistant Examiner:
Attorney, Agent or Firm: Vinson & Elkins

An improved fiber optic matrix coding method and apparatus for a radiation image amplifier is disclosed. The improved method and apparatus permits the determination of the location of detected incident radiation to within an area approximately equal to the cross-sectional area of one of the optical fibers in the coding matrix, thereby providing a four-fold reduction in the number of optical fibers currently required to obtain a radiation image of comparable resolution. The improved method and apparatus also yields a four-fold improvement in the resolution of the timing pulse, thereby permitting the achievement of correspondingly higher rates for processing radiation image data.

DETAILED DESCRIPTION An object of the invention is to provide an improved matrix coding method and improved matrix coding apparatus for attaining increased levels of image resolution and time resolution in a radiation image amplifier.
Another object of the invention is to provide an improved matrix coding method and improved matrix coding apparatus for locating the position of a scintillation with an accuracy of one fiber diameter.
As will be more fully discussed below, since the matrix coding method disclosed in U.
S.
Pat.
No.
3,652,855 is capable of locating the position of a scintillation only with an accuracy of two fiber diameters, the present invention provides a four-fold reduction in the number of optical fibers required to produce an image without decreasing the level of image resolution.
Another object of the invention is to provide an improved matrix coding method and improved matrix coding apparatus for detecting and measuring a large optical signal arising from the scintillation caused by detected incident radiation.
The detection of said signal permits a four-fold increase in the rate for processing radiation image data.
These and other features of advantage of this invention will be apparent from the drawings, the detailed description, and the appended claims.
