This work describes the development of a in-vivo spectral-domain optical coherence tomography system allowing retinal imaging during the maturation of the mouse. These developments were applied to characterize retinal development through morphological and microstructural changes in the retina.
BP-1-26-2 / In-vivo, non-contact, cellular resolution imaging of the human cornea and limbus with line-field SD-OCT

We present the first line-field spectral-domain optical coherence tomography (LF-SD-OCT) that combines 2 x 2 x 3 um resolution in biology tissue with a 2.5 kHz frame rate for in-vivo non-contact, volumetric imaging the cellular structure of human anterior eye segment.
BP-1-26-3 / Time-domain Raman Spectrocopy on Biological Tissues

In Raman spectroscopy, small signal-to-noise ratio as always been an issue, especially in the strongly fluorescent environment of biological tissues. While Raman systems are already used in biomedical applications, such as tumor detection, they still require heavy data processing. Time discrimination is one of the most efficient approach to isolate Raman signal from intrinsic Fluorescence. We present here a Raman Spectroscopic system based on Time-Correlated Single-Photon Counting (TCSPC) and a Time-Gated Single Photon Avalanche Diode (TG-SPAD). We demonstrate the system can perform fluorescence-free Raman measures on beef tissue samples.
