Research

Objective: Fusing biomedicine and optics using novel optical tools to tackle diagnostic and measurement problems in biomedicine.

Advantages of optical approaches:

• High resolution (~ mm), high sensitivity (~ nm or less)
• Non-invasive, non-destructive
• Wide range of light-matter interactions to exploit
• Fluorescence, Raman, non-linear light generation, …
• Coherence phenomena
• Technological tools available from optical telecommunications
• Low cost

The major effort of this laboratory can be roughly divided into the following categories:

Coherence Domain Probing Systems

• Brief Overview of Optical Coherence Tomography (OCT)
• Paired Angle Rotation Scanning OCT (PARS-OCT) Probe
• Differential Interference Contrast (DIC) Microscopy
• Molecular Contrast OCT (MCOCT)
• Homodyne En Face OCT
• Harmonically-matched Gratings-based Quadrature Phase Imaging
• 1/f noise in low signal optical detection schemes
• Hand-Held Forward-Imaging Needle Endoscope for Ophthalmic OCT Inspection

Nanophotonics and Optofluidics

• Optofluidic Microscopy (OFM)
• Slanted Hole Array Beam Profiler (SHArP)
• Long-term Culture, Manipulation and Imaging platform for C. elegans
• Nanofluidic Fluorescent Display (NFD)

Turbidity Suppression by Optical Phase Conjugation in Biological Media

• Turbidity Suppression by Optical Phase Conjugation (TSOPC) in Biological Media
