With a total of 2 patents to his name, Sprague's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Sprague's latest patents is the "Acousto-optic snapshot recorder." This apparatus is designed for recording a serial line of electrical data as a spatial array of optical data. It employs an acousto-optic device through which the electrical signal is passed as a continuous acoustic wave. The device is illuminated by a laser and imaged onto a recording medium to form an image of the acoustic wave. By pulsing the laser as the acoustic wave fills the device, a line of optical data can be recorded, corresponding to the acoustic wave. This method allows for the recording of an entire raster by indexing the recording medium and reimaging with each new acoustic wave.
Another notable patent is the "Method and apparatus for detecting cosmetic defects in ophthalmic lenses." This invention provides a means for detecting and analyzing cosmetic defects on the surface of ophthalmic lenses. The apparatus scans a narrow beam of light across the lens surface, using an array of photodetectors to detect how the beam is scattered or deflected by defects. The system is designed to automatically distinguish between cosmetic defects and external surface debris, making it particularly useful for inspecting finished ophthalmic lenses.
