Latest Patents
One of McCullough's latest patents is for a Non-delineated semiconductor detector array for infra-red. This innovative detector comprises an elongated strip of semiconductor material that is photoconductive. It generates electron and hole photocarriers when an image is moved along the strip. The design includes an active region and a readout region, with a first bias current applied through the active region to produce an ambipolar drift of photocarriers. This drift's velocity matches the movement of the image along the strip. A second bias current is applied to the readout region, allowing for a faster drift of photocarriers, which decreases the time required for readout.
Another significant patent is the Electronic zoom system. This system utilizes wide-angle and narrow-angle vidicon cameras, along with a display and an electronic system controlled by an operator. It blends and magnifies signals from the cameras, providing the viewer with a zoom capability for the display without any effective loss of resolution.
