Method and device for the manufacture of projection cinematographic of the type called a full day and a screen produced by this

摘要

the invention concerns a method for the production of tageslichtprojektionsschirmen with a linsenmatrix and essentially in the focal plane of the linsenmatrix arranged blendenmatrix, which for the purposes of the production of electromagnetic radiation by the blendenoeffnungen linsenmatrix on the blendenmatrix plastic.by the corresponding type of radiation veraenderbare shift of focus. erfindungsgemaess is now envisaged that as electromagnetic radiation, laser radiation is used, which by warmth in the sense of the production of the blendenoeffnungen impressionable, the laser light absorbing layer strong focus.it generates with tip laser light with an absorbent surface locally readings of high-energy concentration, resulting in a strong erwaermung which, depending on the material properties to melting, verdampf or sublimationsvorgaengen can lead.in the layer by thermal ausgleichsvorgaenge can most brief action of sufficiently high power densities eingeschraenkt greatly, so that the zustandsaenderungen detailed weather forecasts in the field shift.this is achieved by abruptly occurring local evaporation of schichtmaterial raeumlich circumscribed parts of the layer of thermal - mechanical wear. ...u.s.w
