The technology of manufacturing of a 256-layer diffraction harmonic lens and the algorithms for reconstructing the obtained images are described. This optical element, created by the research group of the Department of Supercomputers and General Informatics of Samara University, weighs only 5 grams and replaces a complex and massive system of lenses and mirrors similar to the one that is used in telephoto lenses with a focal length of 300 mm and a weight of 500 grams. "To solve the problems in the areas where there is a constant struggle for the reduction of the weight and size of the optics, such massive systems are not suitable. First of all, it concerns compact systems of Earth remote sensing set on small-sized aircrafts, i.e. UAVs, atmospheric probes and nanosatellites. Ultralight diffraction-optical systems weighing only a few grams open up new possibilities for them", – says one of the authors of the scientific article, Professor of the Department of Supercomputers and General Informatics Artem Nikonorov.
Lockheed Martin will soon launch a unique wideband Electronically Steerable Antenna (ESA) payload demonstrator to show the company's investment in advanced technology to perform missions faster once on orbit. The payload demonstrator, which will launch aboard Firefly Aerospace’s Alpha rocket, extends Lockheed Martin’s significant investment in scalable wideband ESA technology development to showcasing an actual on-orbit capability. This technology is critical to future remote sensing architectures.
