摘要： An imaging system (30, 30′) and corresponding method has a two-dimensional imaging sensor array (32) and an associated optical system. The optical system includes at least one optical arrangement (34, 36a, 36b) defining a field of view (38a, 38b) of given angular dimensions and an optical switching mechanism (40) for alternately switching an optical axis of the imaging system between two directions (42a, 42b). The optical switching mechanism and the optical arrangement(s) are deployed such that the imaging sensor array generates images of at least two generally non-overlapping fields of view of equal angular dimensions and with diverging optical axes in fixed spatial relation. Rapid switching between the fields of view allows quasi-continuous monitoring of a larger field of view than would otherwise be possible while maintaining sensitivity to transient events. Also disclosed is an infrared search and tracking system based on such imaging systems.

摘要： An imaging system (30, 30′) and corresponding method has a two-dimensional imaging sensor array (32) and an associated optical system. The optical system includes at least one optical arrangement (34, 36α, 36b) defining a field of view (38a, 38b) of given angular dimensions and an optical switching mechanism (40) for alternately switching an optical axis of the imaging system between two directions (42α, 42b). The optical switching mechanism and the optical arrangement(s) are deployed such that the imaging sensor array generates images of at least two generally non-overlapping fields of view of equal angular dimensions and with diverging optical axes in fixed spatial relation. Rapid switching between the fields of view allows quasi-continuous monitoring of a larger field of view than would otherwise be possible while maintaining sensitivity to transient events.
