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. The image sensors may be moved, relative to each other, along their optical paths. An image processor combines the collected images into a resultant image. Adjustment of the relative positions of the image sensor and/or the diameter of the variable aperture permits the selection of optical properties desired, with a larger depth of field, and/or higher resolution than possible with a conventional system. 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.

Borescopes, such as chip-on-a-tip laparoscopes and endoscopes, having variable and/or active focus lenses. In some preferred embodiments, a chip-on-a-tip borescope may comprise a tip assembly having a fixed focus lens and an active or variable focus lens. The active lens may be part of an active lens assembly, which may comprise a substrate, such as a printed circuit board, along with an active lens unit that may be configured to receive electrical signals, such as voltage steps, that may be used to change the shape of the lens component of the unit to change the focal distance of the device. The substrate may be physically coupled to other elements of the scope and may be electrically coupled with other elements of the scope, such as a voltage driver that may be provided in a printed circuit board in the handle of the scope, for example.
