Makers of AR/MR devices and smart glasses must address the needs of the approximately 60% of consumers who require vision correction. Prescription optics will interfere with standard display quality measurement methods; manufacturers must accommodate those optics to ensure that display performance meets quality standards. This webinar will discuss methods used to measure XR devices with prescription optics, including a new, more efficient method for production testing.
Overview
For AR/MR devices and smart glasses to achieve broad adoption in the mass market, device makers must address the needs of the approximately 60% of potential users who require prescription vision correction. There are thousands of individual prescription permutations for near-sightedness, far-sightedness, and astigmatism, but any prescription lens embedded or inserted into an XR device will interfere with standard display quality assessment. Manufacturers must accommodate this vast variety of AR/MR device optics when assessing key visual performance characteristics such as MTF, uniformity, and distortion.
This webinar describes the optical challenges faced by designers and manufacturers of prescription AR/MR devices and provides a review of current prescription lens compensation technology. The predominant solution for measuring displays with prescription optics is to rely on reverse compensation optics, and the benefits and challenges of this method will be explored. This webinar also will present novel, patent-pending solutions that include both software-driven and hardware approaches. A review of study results will demonstrate this method’s effectiveness at measuring prescription AR/MR devices and meeting the needs of manufacturing production
Key Takeaways
- Review the optical requirements of measuring AR/MR devices with prescription vision correction
- Explore the principles of compensating for prescription optics, including both spherical (near/far-sighted) and cylindrical (astigmatism)
- Discuss current compensation methods and challenges, and learn about a novel method for prescription device compensation
