An imaging device has a lens for focusing light and a sensor for imaging that light. The lens is selected such that the focus coverage area projected from the lens is much greater in area than the area of the sensor. The sensor is moved through the coverage area of the lens linearly along mutually perpendicular axes that are also perpendicular to the axis of the lens allowing the field of view of the lens to be systemically scanned by the sensor utilizing only linear translational motion of the sensor.
