Publication number: 20140285883Abstract: Liquid lens cells are used in a compound variable power optical system that forms an intermediate image between the object and the final image. A first variable power optical component is located between the object and an intermediate real image. The first variable power optical component varies power to change the magnification of the intermediate real image. A second variable power optical component is located between the intermediate real image and the final image. The second variable power optical component varies power to change the magnification of the final image. At least one of the first and second variable power optical components is stationary on the optical axis and comprises at least two liquids with different refractive properties and at least one variable shape contact surface between the two liquids, with variations in the shape of the contact surface producing a change of optical power in the optical system.Type: ApplicationFiled: January 27, 2014Publication date: September 25, 2014Applicant: BLACKEYE OPTICS, LLC.Inventors: JAMES H.

Patent number: 8503074Abstract: A multi-wavelength band imaging system including a beam splitter is provided, allowing image capturing means adapted to specific wavelength bands to be used such as from visible to near infrared, intermediate infrared and far infrared. 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. The imaging system includes a first convex mirror and a second concave mirror. 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.Type: GrantFiled: March 18, 2008Date of Patent: August 6, 2013Assignee: DSAM London LLPInventors: David W.
