OPTICAL ARRANGEMENT

摘要

A multi-wavelength band imaging system including a beam splitter is provided, allowing image capturing means adapted to specific wavelength bands to be used. The system may have a field of view of substantially (360) degrees about an optical axis of the system and may fit into a golf ball sized housing. Some embodiments for imaging single or close wavelength bands and not requiring a beam splitter are equally provided. Also provided is a self-righting housing for an imaging system, for example as described above, which self-rights under the action of gravity, thereby disposing the imaging system in an appropriate orientation.
