COMMON-APERTURE MULTISPECTRAL TRANSDUCER Russian patent published in 2004 - IPC

FIELD: instrumentation engineering.

SUBSTANCE: proposed transducer intended for use in multispectral active-passive systems for detecting and identifying objects in noisy atmospheres and high-frequency tracking of objects by angular coordinates has common aperture integrating microwave, optical, and infrared bands. Common aperture has planar single-pulse microwave antenna mounting on its non-radiating end circular mirror lens and two-spectrum matrix photodetector with spectrum splitter and cooling device. Circular mirror lens has concentric parabolic and hyperbolic circular mirrors. This lens accumulates peripheral light beams incident on aperture and conveys them at right angle towards antenna axis wherein they are focused by hyperbolic circular lens.

EFFECT: reduced space requirement of common aperture and enlarged angular domain for its pumping in front hemisphere space.
