Phase Contrast Microscopy With Oblique Fields
Phase contrast microscopy is an indispensable tool in the biological sciences. I will discuss a new technique for phase contrast microscopy based on oblique field detection with a partitioned aperture. This technique has the advantage that is single shot, light efficient, exhibits a large dynamic range, and can be operated with incoherent broadband light. New advances in this technique include extended depth of field operation by numerical refocusing. We have applied this technique to dynamic live cell imaging and flow cytometry applications. I will also discuss a variant of this technique based on oblique illumination, more specifically oblique back-illumination, which enables speckle-free, simultaneous phase/amplitude imaging in arbitrarily thick tissue. We have applied this to blood flow imaging and are currently developing a miniaturized endomicroscope for in-vivo small animal imaging.
MEETING SPONSORED BY
Jerome Mertz, Boston University
Jerome Mertz received an AB in physics from Princeton University in 1984, and a PhD in quantum optics from UC Santa Barbara and the University of Paris VI in 1991. Following postdoctoral studies at the University of Konstanz and at Cornell University, he became a CNRS research director at the Ecole Supérieure de Physique et de Chimie Industrielle in Paris. He is currently an associate professor of Biomedical Engineering at Boston University. His interests are in the development and applications of novel optical microscopy techniques for biological imaging. He is also author of a textbook entitled Introduction to Optical Microscopy.

General Information on NES/OSA Meetings
Cancellations and No-shows:
If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.
We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.
NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
