Abstract: An optical device, generally a camera head connected to an endoscope, provides multiple modes of operation, producing images with varying depth of field and/or resolution characteristics. Light from the endoscope passes through a variable aperture and a beam splitter and is directed to two or more independent image sensors.

Images may be collected through multiple acquisition periods, and a further enhanced image may be generated therefrom. The camera head may automatically make adjustments based on identifiers of the optical configuration of the attached endoscope.

Abstract: The present invention describes a system for changing the properties of the lenses to create changes in focus, magnification, and optical stabilization without changing the shape of the lens or moving the lenses. It uses an acoustic wave that when propagated through the lenses, creates a standing wave that changes the diffractive capabilities of the lens.

The system described in the present invention involves the development of a lensing mechanism that comprises one or more acoustio-optic modulator(s), a transparent or semi-transparent substrate where the modulation is applied, and a non-parallel standing wave being propagated in the substrate.
