With high light transmittance and natural zoom, CREAL launches an AR optical module that combines light field and HOE

Recently, CREAL, a Swiss AR/VR light field display technology company, announced a new highly transparent AR optical solution and is expected to demonstrate it at Display Week and AWE this month. According to reports, this solution has a number of features, including supporting natural vision zoom, being compatible with curved and prescription lens processing technologies, and being able to customize vision correction parameters according to personal needs. The focus of its technology is HOE film, which can be directly superimposed on traditional eyeglass lenses. The advantage is that it can not only retain the thin, beautiful appearance of the glasses, but also display natural AR images, and has low manufacturing cost and complexity.

We know that CREAL focuses on the development of light field display technology. The principle is to project high-density light in physical space to form/reconstruct 3D objects, so it has natural depth visually. The company is studying the use of optical solutions based on HOE (holographic optical elements) to introduce light field technology into AR glasses. HOE is a very thin film that acts as a light combiner and can generate AR images using light emitted by a light field optical engine.

Judging from the promotional materials released by CREAL, this AR solution can dynamically switch the focal length at a distance between 20 cm and 3 meters, and there is no obvious artifacts such as light leakage on the surface. The optic-equipped temples integrate the laser light source, light modulator, and imaging optics to function as an optical engine.
