Abstract
An automatic zoom-sensing riflescope display adapter (RDA) system can illuminate an iris of a user with a beam from a light emitter. The RDA system can activate a display which includes at least one graphical element visible by the user through an eyepiece. Additionally, the RDA system can focus an image of the iris on a sensor. The RDA system can determine a diameter of the iris from the image of the iris using an iris analyzer. The RDA system can develop a calibration table that correlates the diameter of the iris to a zoom level of an optical scope. The RDA system can estimate the zoom level of the optical scope from the diameter of the iris via the calibration table. Additionally, the RDA system can adjust, to match the zoom level, a font size of the at least one graphical element of the display.
