Abstract
Abstract An optical system for distorted imaging of an object, especially for photographic cameras, is based on a distorting optical system (1) consisting of at least one lens where at least one of the lenses has at least one asymmetric aspherical optical surface and/or of at least one diffractive element, where at least one diffractive element has a surface with asymmetric diffractive structure and/or at least two lenses with mutual general space orientation. The following relations apply to the orthogonal co-ordinates (x, y, z) of any point of the object whose image is to be distorted, and the orthogonal co-ordinates (x', y', z') of the image of this point with the required distortion:where N>=1 is an integer number, ai, bi, ci are weight constants of distortion in the appropriate direction and fi(x,y,z), gi(x,y,z), hi(x,y,z) are functions for ensuring achievement of the chosen required image distortion.

Total Claims: 10
Claim 1
Independent Claim
225 words
An optical system for distorted imaging of an object, especially for photographic cameras, said optical system comprising: at least one lens, where at least one lens has at least one asymmetric aspherical optical surface and/or at least one diffractive element, where at least one diffractive element has a surface with asymmetric diffractive structure and/or at least two lenses in mutually general orientation in space, while the following relations apply to orthogonal co-ordinates (x, y, z) of any point of an object whose image is to be distorted, and the orthogonal co-ordinates (x′, y′, z′) of the image of this point with the required distortion: x ′ = ∑ i = 1 i = N a i f i ( x , y , z ) , y ′ = ∑ i = 1 i = N b i g i ( x , y , z ) , z ′ = ∑ i = 1 i = N c i h i ( x , y , z ) where N≧1 is an integer number, a i , b i , c i are weight constants of distortion in the appropriate direction and f i (x,y,z), g i (x,y,z), h i (x,y,z) are functions for ensuring achievement of the chosen required image distortion.
Claim 2
Dependent Claim
225 words
An optical system for distorted imaging of an object, especially for photographic cameras, said optical system comprising: at least one lens, where at least one lens has at least one asymmetric aspherical optical surface and/or at least one diffractive element, where at least one diffractive element has a surface with asymmetric diffractive structure and/or at least two lenses in mutually general orientation in space, while the following relations apply to orthogonal co-ordinates (x, y, z) of any point of an object whose image is to be distorted, and the orthogonal co-ordinates (x′, y′, z′) of the image of this point with the required distortion: x ′ = ∑ i = 1 i = N a i f i ( x , y , z ) , y ′ = ∑ i = 1 i = N b i g i ( x , y , z ) , z ′ = ∑ i = 1 i = N c i h i ( x , y , z ) where N≧1 is an integer number, a i , b i , c i are weight constants of distortion in the appropriate direction and f i (x,y,z), g i (x,y,z), h i (x,y,z) are functions for ensuring achievement of the chosen required image distortion.
Claim 3
Dependent Claim
25 words
An optical system according to claim 1 , wherein the distorting optical system is located between the first optical system and the second optical system.
Claim 4
Dependent Claim
