When using AR, VR, or MR, a viewer perceives the real world through specialized optics that enhance or alter their experience. If these optics cause issues such as God Rays, the Rainbow Effect, or vergence-accommodation conflicts, the user experience will suffer, potentially discouraging users from engaging with virtual reality. Additionally, a heavy, bulky headset can detract from the VR experience. However, advances in optical metrology are enabling the design of imaging systems that effectively mitigate these issues.

In virtual reality (VR), the real world is replaced by a new  3D digital environment. Augmented reality (AR) overlays digital content onto the real world, while mixed reality (MR) contains superimposed digital content that interacts to some degree with the real world. Optical products for AR/VR/MR are designed to minimize chromatic aberration and ensure a consistent exit pupil for clear visuals. They account for the characteristics of human eyes and often incorporate eye tracking technology to enhance user experience and maintain precise visual alignment.

When a point light source is observed, an aplanatic optical system concentrates a light beam into one point at the image location. Contrarily, an optical system with aberration does not concentrate the beam into a point, resulting in a divergence. Figure 1 shows the appearances of a point image (intensity distribution of a point image) in both optical systems.

Note: A laser interferometer is used for actual optical performance evaluations, thus providing evaluation with a single wavelength. Unless otherwise noted, Olympus offers Strehl ratio values measured with the e-line laser (544nm).

While the roles of telecommunications, computer coding, and graphics design in AR, VR, and MR are well recognized, it is the optics that truly lie at the heart of successful spatial reality experiences. The quality of these optics can make or break AR/VR/MR devices.

A Strehl ratio of 80% is commonly known as the diffraction limit. An objective lens below this limit is not assumed to have satisfactory performance. An objective lens with a Strehl ratio of more than 95% compares favorably with an aplanatic lens in performance for common observations.

In VR optics, Fresnel lenses are commonly used, particularly in higher-end models. These lenses are essential for achieving a lightweight head-mounted display, where minimizing eye-position-dependent distortion is crucial. Such distortions can lead to motion sickness, making their elimination a top priority for enhancing user experience.

Assuming a convergence ratio in the image field of an aplanatic optical system (light intensity converging on an airy disc) as 100%, the convergence ratio in an optical system with an aberration is referred to as a "Strehl Ratio (SR)". As shown in the graph in Figure 2, an optical system with a higher SR value is closer to an aplanatic optical system.

Unlike the basic lenses traditionally found in viewfinders, a Fresnel lens is crafted from optical plastics with concentric rings precisely carved into its surface. These lenses feature a large aperture and a short focal length. The engraved rings divide the lens into concentric sections, creating a series of surfaces with identical curvature, separated by discontinuities. This design causes light to bend differently depending on which part of the lens it passes through.
