Latest Patents

One of Abel's latest patents is an autofocus system for infrared imaging devices. This apparatus continuously determines the position of the best focus of an objective lens and features a system with a video output. The technique employs a transmissive plate of variable thickness, strategically placed on one side of the field stop of the optical system. This plate covers the full vertical field and encompasses approximately 30 to 40 resolution elements in the horizontal direction. The plate is divided into platelets of different thicknesses, designed to cover the range of defocus while discriminating against variations in scene content. Importantly, the plate is positioned outside the active area displayed by the video, ensuring that the variations introduced do not affect the video output but are utilized for continuous focus determination. Additionally, a spherical shell of zero power may be placed between the objective lens and the field stop to create a bias, distributing focal shifts around a nominal position.

Another significant patent by Abel is the reflective Schmidt system with a nonrotationally symmetric corrector. This innovation achieves wide field of view correction for wide spectral band imaging systems through the use of a fold mirror that also serves as a corrector plate. The method for fabricating this corrector plate is also described in the patent, showcasing Abel's comprehensive approach to solving complex optical challenges.
