20130206995 | Directional Radiation Detection Apparatus and Method Using Inverse Collimation - The present invention provides a radiation detector for detecting both the intensity and direction of one or more sources of radiation comprising a radiation sensor, an inverse collimator that shields the sensor from at least a portion of the incident radiation originating from the direction in which the inverse collimator is pointed and a means for pointing the inverse collimator in different directions. In accordance with another aspect of the invention, there is provided a method for detecting both the intensity and direction of one or more sources of radiation comprising the steps of providing a radiation sensor, providing an inverse collimator that shields the sensor from at least a portion of the incident radiation originating from the direction in which the inverse collimator is pointed, providing a means for pointing the inverse collimator in different directions, pointing the inverse collimator in a direction, recording the direction in which the inverse collimator is pointed and recording the signal from the sensor, repeating the preceding two steps one or more times for one or more different directions. | 08-15-2013 |
