Abstract:
A new Laser scanner system does replace all known laser scanner systems, that either are galvanometer based or not. It makes possible to steer a beam of even high intensity very precisely in one or two dimensions. The system can deflect a beam in very fine steps (deflection angles), with a repetition rate of potentially better than even some GHz. A possible embodiment includes a cascade of “deflection elements”, that are based on switching (thin) films. The switching films might be metallic films, or stacks of alternating dielectric films, that change their optical properties under switching electrical loads (planar areas of sufficient dimensions that are switching within ns) and become highly reflective—to the order of 99,999%. Even other reflective, fast switching films can be used—as long as the highly reflective switching state of the layer (film) is used to select the direction of reflection/deflection of the laser beam. Said film would otherwise be in its state of very high transmission and would let the beam pass through—to some next switching layer that would reflect the beam to a slightly different direction. Even adaptive wavefront correction can be achieved by the use of switching films, that in addition to the core idea and concept for the laser scanner are arranged in a×y matrix, like a CCD, hereby granting the high throughput that might be necessary for a GHz laser scanner adaptive wavefront correction. Possible other applications of such a distortion correction elements exist many in adaptive optics. From beam steering in laser machining to bar code scanners, to laser based tv systems the proposed system brings technology into existence that is orders of magnitude faster than what is in use right now. Especially in the area of laser based machining and production, it would be possible to produce with a far higher throughput and precision than with conventional galvanometer based systems.

Claim (Index 8):
an adaptive optics element (stack) comprising:\n a combination of m switching films (xy matrices of switching films), and transparent layers\u2014spacers\u2014of various thickness; said stack of in combinations of films and transparent layers covering various overall lengths, eg. a stack covering the dozens of micrometer range (or even more for a four stacks cascade setup), then a second stack with smaller spacers covering the range up to eg. 3 micrometers and a last one covering the range of eg. 200 nm; said stack of combinations of films for the range of 200 nm comprising: possibly only switching films, because the switching film itself covers the needed depth/thickness of approximately 15 nm (13 pieces of 15 nm thickness make 195 nm), at least in the case of a metallic film; said xy resolved matrices of switching films comprising: a separation tot he next matrices in the stack by using possible fixed length transparent spacers in between; said xy matrices comprising a means to: correct the phase of an incident laser beam on a \u201cper pixel\u201d basis, said correction adding up to a total amount of correction on passing through the sequence of phase correction stacks on sequentially entering the stacks with higher overall length, leaving them and subsequently entering the ones with ever smaller overall length\u2014or phase correction ability. Hereby phase correction adds up to the necessary amount of phase correction with fine enough discrete phase correction steps; said xy matrices comprising: switching films that might include electrodes that are made of highly transparent metallic material\u2014to make electrical switching possible without distorting the beam; said xy matrices optionally making switching possible without electrodes by employing a laser beam that targets individual pixels on the xy matrix\u2014as a possible nonelectronic alternative to switch the optical properties of the switching layers;
