| description | Traditional focusing system usually uses multilenses by moving two concentric lenses towards or
away from each other. However, the small and compact
implementation using multiple-lenses is difficult to
achieve since a certain distance between two- lenses is
required for different focal length. To overcome this
problem, in this paper, a new focusing system based on
flexible lens is introduced. The flexible lens is made
from natural rubber membrane and water, which is used
as the optical medium. In the proposed system, focusing
is achieved by the change of volume of water inside the
lens. A passive control algorithm for auto-focusing has
been employed using LabVIEW, a graphical
programming language. The experiments show that the
proposed flexible lens is capable of projecting colored
images onto the CCD sensor for objects lying at a
distance of 100 mm to 7000 mm from the camera. |
