Eye-safe 3D measurement technology in SWIR
Conventional 3D measuring systems usually operate at wavelengths around 800 nm, due to the blindness of the human eye in this spectral range. Unfortunately, the damage potential of optical radiation at these wavelengths is high since the eye is highly transparent for light up to a wavelength of 1400 nm. This hitherto complicates a tightly interlinked man-machine-interaction, which is based on a three-dimensional perception of humans, for example the state of mind (facial expressions and gestures) by empathic machine systems.
In order to solve this problem, the research group "Eye-Safe 3D Imaging in the SWIR" aims at the technical establishment of an efficient 3D measurement technique in the shortwave infrared (SWIR), especially at 1450 nm.
