Researchers from Purdue University have been developing a technique that could one day replace using needles for blood tests with volumetric imaging.
The technology uses an InSight SeepSee femtosecond laser that travels deep into the tissue.
“The laser system has two 100-fs pulses — one at 1040 nm with the other tunable from 680 to 1300 nm — giving the user the ability to tune the laser to excite different vibrational transitions of the specimen,” according to Photonics Media.
