Interferometric method for controlling the assembly quality of an optical system with an eccentrically arranged aspheric lense

Resumo

This paper describes the interferometric method for controlling the assembly quality of a three-lens unit of an optical system of a decentered nine-component optical system of an aircraft helmet wide-angle display collimator. It is shown that this alignment method makes it possible to establish optical components, including the off-center aspherical lens, with an error of one micron. The method is contactless and allows for the control of the position of lenses inside the body of the device.
