Abstract
Disclosed embodiments include means and methods of automatically measuring numerous characteristics of an optical system, such as an eye. Measured or displayed optical properties may include but are not limited to. spherical power, cylinder and axis for astigmatism. Higher order optical aberrations may also be measured. Disclosed embodiments may be used to measure refraction for creating corrective lenses for eyeglasses and contact lenses. Measurements of higher order aberrations of an eye may be used for measuring enhanced correction, accommodation state and range.
Claims5
A method of measuring properties of an optical system, the method comprising the steps of:
- a) projecting a predefined image through a deformable lens with a resulting image projected upon a focal plane of the optical system;
- b) using an array detector to measure an image reflected form the optical system;
- c) using the deformable lens to reshape the resulting image projected to the focal plane until the reflected image measured by the array detector comports with the predefined image;
- d) using the final refraction of the deformable lens as the derived optical system properties.
