<p>A method of generating a target surface S (» ) of an optical lens according to optical lens parameters » , the method comprising: providing a set of L first surface difference data E(A j ) each first surface difference data E(A j ) corresponding to the surface difference between a pre-calculated surface S » j pc ± » j �¢ j = 1 , €¦ , L and an initial surface S » j ini j = 1 , €¦ , L , from which the target surface will be generated, according to the expression : E » j = S » j pc ± » j - S » j ini j = 1 , €¦ , L
where » j ( j = 1,..., L ) correspond to the optical lens parameters of the pre-calculated optical lenses; providing a set of second surface difference data E (» ) corresponding to the surface difference between the target optical surface S (» ) and the initial surface S » €¾ ini by linear interpolation of the first surface difference data E (» j ) according to the expression: E Ü » €¾ = ˆ‘ j = 1 L w j » €¾ �¢ E » j , where w j » represents an interpolation coefficient; and; determining the target surface S (» ) by combining the second surface difference data E (» )and the inital surface S » €¾ ini according to the expression: S Ü » €¾ = E Ü » €¾ + S » €¾ ini</p> |
