Latest Patents

One of his latest patents is a narrow band transmitting-receiving telescope system. This innovative system allows for the direction of reception and transmission to be changed without external manipulation of the system container. The core component of this system is a narrow-band transmitting-receiving telescope apparatus, which features a rotating diffraction grating and an independently rotating stage. This setup includes a combination of a photodetector for reception and a laser for transmission, along with a focusing system that concentrates the beam reflected from the grating onto the photodetector or sends a beam from the laser onto the grating. The selection of specific angles for signal transmission and reception is achieved through the corresponding rotation of the grating and rotating stage. This apparatus is designed for spectrally selective transmitting or receiving of optical radiation, boasting advantages such as compactness and the ability to receive and transmit light with a specific wavelength from any direction without altering the physical structure of the apparatus.

Another significant patent involves high efficiency volume diffractive elements made from Bragg diffractive gratings in photo-thermo-refractive (PTR) glass. These elements exhibit absolute diffraction efficiency ranging from over 50% to more than 93%, with total losses below 5%. Both transmitting and reflecting volume diffractive elements are crafted from PTR glasses, which allow for high spatial resolution and the recording of spatial frequencies up to 10,000 mm. The applications of these diffractive elements include angular selectors, spatial filters, attenuators, switchers, modulators, beam splitters, and more, showcasing their versatility in various optical applications.
