Patent ID: 8405904

Claim:
A device for superimposing an image onto an image of an observed object observed through an aiming optic of the type having a beam path along which is carried observation light representing the image of the observed object, said device comprising: an at least partially transparent optical support element, said optical support element having at least one diffractive optical decoupling element located in the beam path, said optical support element also having at least one diffractive optical coupling element located outside the beam path, said optical coupling element receiving incident light of the image to be superimposed onto the image of the observed object and coupling said light of the image to be superimposed into said optical support element, said optical support element internally guiding said light of the image to be superimposed to said optical decoupling element, said light of the image to be superimposed exiting from said optical support element and being imaged into said beam path by way of said optical decoupling element.
