30 May 1995 Potential for optical imaging in the 1 to 1.3 micron range using an upconverting time gate

Performing imaging in the wavelength region of 1 to 1.3 micrometers is attractive because the scattering coefficient is up to a factor of 2 less in this wavelength region than at wavelengths commonly used near 800 nm. While hemoglobin absorption cannot be used for contrast at the longer wavelengths, the requirements for contrast are reduced, and other contrast sources are available. Higher numbers of photons may be used for imaging in this longer wavelength region. Longer wavelength imaging is challenging because the detectors operating beyond 1 micrometers , we have developed upconverting time gates that upconvert images from longer wavelengths (1-1.3 micrometers ) to wavelengths below 1 micrometers where good detectors exist.
