Introduction: Robert Aprahamian is an accomplished inventor based in Hermosa Beach, California, known for his groundbreaking work in optical systems. With a total of five patents to his name, Aprahamian has made significant strides in addressing the challenges posed by wavefront aberrations in large optical elements, enhancing imaging systems and improving their efficiency.

Latest Patents: Among Robert Aprahamian's latest innovations are two noteworthy patents that showcase his expertise in optical engineering. The first patent, titled "Large Optics Compensated Imaging Systems," introduces a technique for correcting wavefront aberrations introduced by large primary optical elements in various portions of the electromagnetic spectrum. This method involves transferring the aberrations of the primary element to a beacon beam, which is then interfered with a reference beam in a holographic medium. By allowing a beam from a distant object, containing the same aberrations, to diffract from the hologram, Aprahamian effectively removes the aberrations and produces a clearer image. This technique notably permits the construction of large optical elements at a lower cost, since surface tolerances can be considerably relaxed.

The second patent, "Phase Corrector for Large Optical Systems," presents an apparatus and method for removing phase aberrations introduced into incident light waves by large optical elements, such as concave mirrors. Instead of requiring additional precision in the mirror construction, this innovation utilizes collimating and phase conjugating techniques to rectify phase errors. After the initial reflection from the mirror, the adjusted beam is expanded to match the mirror's dimensions before undergoing a second reflection. This process allows for the production of aberration-free images or collimated light beams from diffraction-limited laser sources.

Career Highlights: Robert Aprahamian has successfully cultivated a career focused on advancing optical technology, particularly in his role at TRW Limited.
