Fully Passive and Ultra-Low-Power Technologies for Spectral Enhancement of Human Vision
Abstract
The human visual system enables imaging and perception with high resolution, large dynamic range, and a wide field of view. However, it also has substantial spectral limitations: human eyes are only sensitive to the visible range (covering approximately 400 to 700 nanometers in wavelength), and perceive colors rather than spectra, thereby losing a substantial amount of spectral information. The objective of this research is to explore, design, and implement a set of electronics-free optical devices and systems to enhance human spectral perception. We aim to develop a set of compact electronics-free vision-augmentation devices that enhance the ability to distinguish spectra and extend human vision into invisible ranges of the electromagnetic spectrum, while consuming little or no external power. In the course of this project, we will develop and implement fully passive optical devices in the form factor of a pair of glasses that enhance the wearer’s ability to distinguish spectra in the visible range. These devices will reduce the number of pairs of spectra that appear to the naked eye as the same color by orders of magnitude. We will also develop and implement devices in the form factor of binoculars that convert images from the ultraviolet and/or the infrared into the visible band, greatly extending the spectral range of humanvision. Both fully passive devices and those that consume a nominal amount of external power will be explored.
