Claim 15:
16. A system for imaging biological tissue, the system comprising:
an optical source configured to provide infrared illumination to a region of a subject having biological tissue comprising a first tissue region and a second tissue region, wherein the first tissue region has a first water content level and the second tissue region has a second water content level that is lower than the first water content level, wherein the infrared illumination has an illumination wavelength of 1500-1700 nm;
a sensor configured to sense a first reflected portion of the infrared illumination and a second reflected portion of the infrared illumination, wherein the first reflected portion of the infrared illumination is reflected from the first tissue region and has a first intensity, and wherein the second reflected portion of the infrared illumination is reflected from the second tissue region and has a second intensity that is higher than the first intensity; and
a controller in communication with the sensor and configured to:
receive, from the sensor, information corresponding to the first reflected portion of the infrared illumination and the second reflected portion of the infrared illumination;
generate at least one image of the at least one biological tissue in the subject using the information, wherein the at least one image distinguishes the first tissue region from the second tissue region; and
output the at least one image to at least one of a display and/or a memory.
