Abstract: A method of scanning a laser over a field of view, the method comprising: providing a laser to produce the laser beam; rasterizing the laser beam over a first sub-area of the field of view; deflecting the laser beam to a second sub-area of the field of view; and rasterizing the laser beam over the second sub-area of the field of view; and capturing image information produced by the laser beam so that, for each sub-area of the field of view, the rasterized laser beam defines a plurality of image segments; for each segment calculating an image correction and applying a correction to the laser according to the calculated image correction for the segment, and corresponding system.

Abstract: An aspect of the present disclosure provides a method of fabricating a lens using gravity. The method comprises depositing a first transparent solution on an underside of a flat smooth material. Cross-linking of the deposited first transparent solution is then activated to form a support layer. A second transparent solution is deposited onto the surface of the support layer. Cross-linking of the second transparent solution is then activated.

Abstract: Disclosed is a lens fabrication method (100) which uses a droplet of polydimethylsiloxane (PDMS) solution (210) cured on a slide (214) to form a PDMS support layer (211) having a curved surface (211 a). Further PDMS droplet (210) is then deposited on the curved surface (211 a) of the PDMS support layer (211); the slide (214) is then inverted to allow gravitational force to pull the uncured, further PDMS 110 PDMS solution (210) down. The further PDMS solution (210) on the inverted slide is then cured. Each repetition of depositing, slide-inverting, and curing of the further PDMS droplet (210) adds an additional layer of PDMS, altering the shape and focal-length of the lens.
