Abstract
The present disclosure relates to a system and method for verifying a diopter setting and range of an optical system eyepiece by utilizing an image sensor to view and analyze test patterns of spots displayed within the optical system eyepiece and calculating the diopter setting and range of the optical system eyepiece from an observed change in the test pattern at different diopter settings.
Claims20
A system for verifying a diopter setting and range of an optical system eyepiece comprising:
- an image sensor having at least one lens;
- and
- a non-transitory computer-readable storage medium having instructions encoded thereon that, when executed by one or more processors, result in the following operations for verifying the diopter setting and range of the optical system eyepiece, the operations configured to:
- display a pattern of spots on a display apparatus of the optical system;
- create at least one first image with the image sensor of the pattern of spots displayed on the display apparatus of the system at a zero diopter setting;
- create at least one second image with the image sensor of the pattern of spots displayed on the display apparatus of the system at a first non-zero diopter setting;
- compare the at least one first image to the at least one second image;
- process a calculated diopter setting and a calculated range;
- and
- verify an actual diopter setting and an actual range of the optical system eyepiece are within a predetermined range.
