Method for the determination of the luminance of two-photon vision stimuli.

ABSTRACT: Two-photon vision is a new and developing field in vision science. The phenomenon is based on visual perception of pulsed infrared lasers (800-1300 nm) due to the isomerization of visual pigments caused by two-photon absorption, with color perception corresponding to a wavelength about one-half of the stimulating wavelength in the near-infrared spectral range. Future applications of this effect, both in medical diagnostics and in virtual/augmented reality (VR/AR), require the ability to determine the luminance of the two-photon stimuli. However, the luminous efficiency function V(λ) outside of the visible range is unknown, requiring a non-standard approach to quantifying the luminance of two-photon stimuli. This study proposes a brightness adjustment method to determine the s
