Technology

Security cameras are typically covered by optically transparent plastic domes. For aesthetic purposes it is desirable for these domes to be recessed into the ceiling as far as possible. This, coupled with the need to increase camera aperture size and its focal length, has created performance limitations for these security systems. Until now there has not been a solution to this problem.

Researchers at UAH have developed an optical aberration compensator apparatus to resolve these limitations for camera systems that use a concentric protective dome. The technology consists of a thin lens which corrects the spherical aberration from the dome. The lens is positioned directly in front of the camera and stays in the same position relative to the camera. This lens can be attached by a mechanism that allows for the element to move relative to the camera system to account for different zoom settings, thermal issues, or distances of the objects from the camera.

The technology can also compensate for the optical aberration that occurs at the conical section of the dome by using a single-element thin lens to correct for the power difference. This element can be positioned directly in front of the camera regardless of the camera's tilt.

The device is a two-element mechanical system works at all tilt positions and covers the camera system's entire field-of-view.
