Abstract

See full text

A head-mounted-display includes an electronic display emitting image light and a varifocal block receiving the image light and outputting the image light in at least one of the focal planes of the varifocal block. The varifocal block includes a back optical element, a front optical element, and an actuator assembly coupled to the back and front optical element. The front optical element is positioned closer to an exit pupil than the back optical element, and separated from the back optical element by an adjustable distance, the magnitude of which determines in which of the focal planes the image light is presented. The actuator assembly simultaneously adjusts positions of the back optical element and the front optical element to vary the adjustable distance between the back optical element and the front optical element in accordance with an estimated vergence depth of the user.
