Latest Patents

Grimaldi holds a patent for an "Optical device for scanning still images in television." This invention addresses the challenges associated with scanning still images, especially in high-definition television (HDTV) systems. The device utilizes an optical system with an oscillating mirror to convert the entire still image into a format suitable for a linear sensor equipped with photosensitive elements. To mitigate the diffusion of the optical system, which can cause detachment of dark areas adjacent to bright areas, Grimaldi synchronized the movement of a shutter with the mirror's oscillation. This synchronization allows for the occultation of parts of the image, ensuring that only the relevant zone is captured by the sensor.
