Patent ID: 7019919

Claim:
An optical apparatus having a variable optical-property optical element, wherein a deformed profile of an optical surface of said variable optical-property optical element where said variable optical-property optical element is driven is measured by a measurement device or assumed, a measured value or an assumed value of said deformed profile is compared with an optical design value of an optimum profile of said variable optical property optical element corresponding to one of a zoom state, a distance to an object, and both to adjust a value of a voltage applied or a current supplied to said variable optical property optical element so that said measured value or said assumed value of said deformable profile corresponds with said optical design value of said optimum profile within tolerances, and said value of said voltage applied or said current supplied to said variable optical-property optical element where said measured value or said assumed value of said deformable profile coincides with said optical design value of said optimum profile within tolerances is stored in output information as an optimum voltage value to be applied or an optimum current value to be supplied to said variable optical-property optical element to thereby make a look-up table.
