Outline of Final Research Achievements |
We developed a system enabling the measurement of both structural and molecular information on tissue purely based on label-free technologies. The structural information is retrieved through optical coherence tomography, developed here in a full-field configuration, which enables parallel detection without requiring scanning. This system employs a wide-band excitation source based on a white-light supercontinuum that provides over 100 nm of bandwidth to reach isotropic micrometer resolution. The molecular modality is based on a standard point-measurement Raman scanning system with a near-infrared excitation. While this approach typically requires long exposure times, it is here possible to employ the information retrieved from full-field OCT to specifically target regions of interest to rapidly retrieve the molecular information. The system was characterized with phantoms containing plastic beads and ex vivo tissue.
