Latest Patents

One of Scofield's latest patents is titled "Method of Altering Reflectivity of Optical Elements." This invention provides a method for restricting the mode of operation of long wavelength waveguide lasers by introducing an approximate step function into the reflectivity of circular optical elements. The preferred method involves grinding off a portion of the optical coating of the optical element, leaving a circular unground region of high reflectivity. This innovative approach allows for simple and inexpensive field modifications of existing lasers.

Another significant patent is the "Optical Block for High Brightness Full Color Video Projection System." This invention improves the optical block used in high brightness, full color image projection systems. It utilizes a polarizer to accept the unpolarized output of a high-intensity source, which is then directed through a series of polarization-sensitive dichroic filters and wavelength-tuned biprisms. This system effectively separates incoming light into component wavelength bands, allowing for the creation of a high brightness, full color modulated image.
