Title: Kevin A Hadfield: Innovator in Imaging Technology
Introduction
Kevin A Hadfield is a notable inventor based in Chelmsford, GB. He has made significant contributions to the field of imaging technology, holding a total of three patents. His work focuses on enhancing the performance and functionality of image intensifiers and imaging apparatus.
Latest Patents
One of Hadfield's latest patents is titled "Image intensifiers having means to reduce electromagnetic interference." This invention addresses the challenge of minimizing interference produced by the power supply of an image intensifier. By operating the high voltage power supply intermittently, the intensified image quality is preserved. The input capacitance of the intensifier helps maintain the high voltage at an acceptable level when the power supply is not in operation. This innovation is particularly beneficial when used in conjunction with video cameras, allowing the power supply to operate only during specific synchronization periods.
Another significant patent is "Imaging apparatus with improved synchronization." This invention involves a CCD imaging array that includes one or more shift registers. By injecting a charge packet at one end of the shift register in relation to the start of line readout, the charge packet reaches the other end at the end of the line period. This technique can generate line synchronization signals and can be applied for more complex waveform and field generation.
