Description
One of the main problems with augmented reality (AR: Augmented Reality) technologies is that achieving satisfactory clarity and quality simultaneously: the image of the outside world and the additional information displayed against it requires a compromise.
Current solutions on the market are mainly based on fiber optic technology.
Eyeglasses are specially designed flat optical waveguides that transport light carrying information to the eye and combine it with light coming from the environment. However, both diffractive waveguides (e.g., Hololens) and reflective waveguides (e.g., Lumus Z-lens) affect the course of light from the environment, ultimately resulting in a dimmed and/or distorted image. These problems are exacerbated when the waveguide structure has to accommodate different display colours.
This project aims to verify the potential of implementation of the concept of a retinal display using two-photon vision for the projection of AR content. This is a recently discovered vision mechanism that extends the range of perceived radiation into the near-infrared (850-1300 nm).
Two-photon vision is based on a nonlinear optical process - two-photon absorption occurring in visual pigments. Laser beams that we see due to this process have a color close to half their wavelength: for 950 nm - blue, for 1000 nm - green, and for 1200 nm - red. Due to differences in the wavelengths of ambient light and the AR stimulus, it may be easier to combine the two optical paths in glasses. The nonlinear nature of the phenomenon means that it occurs efficiently only at the retinal focus of the beam, so duplicate reflections, as well as scattered light, are not perceived. Thus, the twophoton stimuli may have better contrast. These hypotheses will be verified by building a prototype AR glasses with two-photon vision and conducting psychophysical tests using it.
