The seminar compares contrast sensitivity in one-photon and two-photon vision. Two-photon vision is based on pulsed near-infrared light and may be useful in augmented-reality displays because it separates the wavelength of added content from the real-world scene. The study introduces two-photon retinal illuminance and shows that two-photon stimuli can offer higher contrast, especially at low and medium spatial frequencies, while remaining within safe illumination levels.
