摘要： A light beam is used to illuminate a spot on a lens element which is shifted along the optical axis of an imaging system for auto-focus or optical zoom purposes. The light beam is arranged such that the reflected light beam from the lens element encounters a spot on the image sensor. The spot location on the image sensor is determined by a signal processor. As the lens element is shifted along the optical axis, the spot location changes accordingly. Based on the moving distance of the spot, the signal processor determines the shifting distance of the lens element and hence the position of the lens element. Based on the shifting distance of the lens element, a control module is used to adjust the lens position along the optical axis to achieve the desired focusing or zooming effects.

摘要： The invention relates to a shutter for an optical imaging system. An amount of opaque fluid is moved in a planar capillary space to open and close the shutter. Depending on the position of the opaque fluid with respect to an optical path passing through the capillary space, the fluid opens or blocks the optical path. In an embodiment, the opaque fluid is moved by a pressure differential caused by a diaphragm which is coupled to a piezoelectric actuator. In another embodiment, the opaque fluid is moved by electrostatic forces.
