OPTICAL FIELD WITH TWO OPTICAL FIELDS AND METHOD FOR TRANSMITTING LIGHT FROM AN OBJECT IN SUCH AN OPTICAL SYSTEM

摘要

An optical system for transmitting light from an object by means of two optical fields, comprises optical means 10 forming two optical paths associated respectively with a wide optical field and a narrow optical field, at least a part of these paths optics being aligned, and blocking means 30 located in said aligned portion of the optical paths and selectively operable to transmit light from the object and associated with one of the optical paths, while simultaneously blocking transmission of the light associated with the other optical path. /P P Application in particular to stabilized platform systems.
