Coefficient 1,5

• Knowing the main methods of optical imaging of living tissue.
• Knowing instrumentation, light sources, detectors and associated acquisition chain.

Optical imaging method (2*1h45mn) Principal methods of measurement and macro imaging of optical properties of organs

• Diffuse Optical Tomography
• molecular fluorescence tomography
• photo-acoustic imaging
• Optical Coherent Tomography

Instrumentation (2*1h45mn) The instrumentation part is oriented to the practical work proposed in this teaching

• Planar Fluorescence, 2D imaging static lighting: laser diodes and CCD camera.
• picosecond time resolved of near infrared spectroscopy, laser diodes, avalanche photodiode, time resolved photon counting.
• time resolved near infrared imaging, 3D imaging (2D + time) image intensifier tube.
• An overview on pulsed light sources in also given

3 practical sessions illustrate the different techniques taught:

• Planar fluorescence imaging
• Absorption and diffusion coefficient assessment by time resolved measurement
• 3D imaging with sub-nanosecond time gate camera.
