Optically shifting the focal plane to allow depth scanning of delicate biological structures and
processes in their natural environment offers an appealing alternative to conventional …

We present the evolution of initial imaging experiments and micro-electro-mechanical
systems mirrors toward a commercialized product. Feasibility of 10-mm-diameter …

Although researchers have proposed varifocus elements for focus and zoom [1], the
technology has not yet reached widespread use in industry. Varifocus elements change …

Variable focus may be achieved without mechanical motion if a liquid ciystal display shutter
is made to scan across a plane behind a freeform progressive lens. Hence, the use of two …
