Optical system maps multiple infrared fields onto one small detector

Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences have developed an optical system that focuses light from several subfields onto a single small-format detector. By analyzing field-dependent spot shapes, the system identifies which subfield an isolated infrared target comes from. In sequence-level tests, it identified the correct field in about 89% of cases. The study is published in Optics and Laser Technology.
