New Apple patent describes optical system for VR headsets

Details of Apple’s new design for a wearable VR device went public last Thursday when the United States Patent and Trademark Office published a patent application Apple filed in 2017 related to optical systems. The patent describes an “Optical System for Head-mounted Display” intended to make VR headgear more comfortable. In the application, Apple notes that VR headsets can be “cumbersome and tiring to wear” due to “bulky and heavy” lens arrangements. VR devices typically use microdisplays, requiring high magnification of visual content and thus thicker lenses between the display and the wearer’s eyes. Currently, many popular headsets overcome this issue by using Fresnel lenses–a type of

19th Century “VR headset” Expected to be Auctioned for More than $2500

A “virtual reality” headset hand-crafted by Sir David Brewster, a Victorian instrument-maker from Dundee, Scotland – is to be offered for sale at an auction next week, according to The Times. The Brewster stereoscope gave the illusion of depth using the same optical technology as VR headsets. The device, made of walnut and satinwood, held two images side by side which, when observed through lenticular lenses, converged into a single three-dimensional image. It was developed by Sir David Brewster, a Scottish physicist, mathematician, astronomer, inventor, writer, historian of science and university principal. Most noted for his contributions to the field of optics, he studied the
