Latest Patents

One of his latest patents is focused on the remote detection of radiation. This invention provides a method for detecting inaccessible radiation sources by measuring corresponding ions and excited molecules created by radiation, utilizing LIDAR technology. The LIDAR system employs a pulsed laser transmitter, a telescope receiver, and associated control and acquisition systems. Light propagates from the laser transmitter into the volume surrounding the radioactive source, known as the 'ion cloud.' The ion cloud absorbs the transmitted light, inducing non-fluorescing ions to fluoresce. The backscattered light is then collected by the telescope receiver, and the intensity of the fluorescence is measured to indicate the number density of the ionized atoms. Algorithms can relate the measured ionization rates to the source activity.

Another notable patent by Roberts is a system and method for measuring the retroreflectivity of materials. This system comprises a light source and a first optical pathway along which an illumination light beam travels to a retroreflective surface. A second optical pathway is provided for the retroreflected beam traveling back to a sensor array. A processor, electrically coupled to the sensor array, determines the intensity of a predetermined pattern of the retroreflected beam, defining the retroreflected light propagating from the surface at a predetermined observation angle.
