A real time SAR processing system for processing synthetic aperture radar (SAR) return signals and a method for real time processing of SAR return signals. The real time SAR processing system for processing synthetic aperture radar return signals comprises a light source () for generating a coherent, plane electromagnetic wave; light modulation means () for modulating the incident wave according to the radar return signals and outputting a modulated wave; and optical processing means () for submitting the modulated wave to an optical signal processing for radar image reconstruction. The light modulation means () comprises a plurality of addressable pixels () which are controlled based on the radar return signals. Light detection means () for detecting the processed wave and generating a corresponding electrical radar image signal are provided.

Real time synthetic aperture radar processing system and method

A self-supported optical correlator has a first holder having two opposite ends, one of the opposite ends being provided with anchor points, the other end being provided with a light source. The correlator also has a second holder having two opposite ends, one of which is provided with anchor points, the other being provided with a light receiving element, and a plurality of intermediary holders, each having two opposite ends provided with anchor points, at least one of the intermediary holders being provided with a spatial light modulator for projecting an image and another of the intermediary holders being provided with another spatial light modulator for projecting a filter. Each of the intermediary holders is provided with optical components secured within the holders. The said anchor points are adapted to secure the first, second and intermediary holders together linearly end to end; so that when the intermediary holders are assembled end to end, and the first holder is assembled at one extremity and the other holder is assembled at another extremity, the resulting assembly forms said optical correlator. The optical components are toleranced, and the anchor point serve to assemble a structure which does not require additional adjustments.

A laser apparatus provided with an aiming beam using a method for the injection of both laser light and aiming beam forming light in an optic fiber will be described herein. More specifically, the present disclosure describes a method, an injection module and a laser apparatus designed to inject laser light into the core and aiming beam forming light into the cladding of the optic fiber.
