Near-infrared imaging of artificial enamel caries lesions with a scanning fiber endoscope
Several studies have shown that near-infrared imaging has great potential for detection of dental caries lesions. A miniature scanning fiber endoscope (SFE) operating at near-infrared (NIR) wavelengths was developed and used in this study to test whether the device could be used to discriminate …

Diffuse photon transport in tissue-like media: Resolution limit for near-infrared imaging and an instrument for clinical spectroscopy of tissues
… I consider the ultimate resolution of near-infrared based imaging of tissues using a simple model to describe resolution. I conclude that for a 5 cm thick tissue, the closest two objects buried in the center can be, and still be resolved is roughly 1.5 centimeters. I also show that …
