CFP: Focus on Microscopy 2008

Sorry Folks,
I didn't post this in time. The deadline is January 15 (This Tuesday). Following announcement came from confocal list.

---------------------------------------------------------------------------------
FOCUS ON MICROSCOPY 2008 - Osaka, Awaji Island, Japan - April 13-16, 2008
----------------------------------------------------------------------------------

21th International Conference on 3D Image Processing in Microscopy
20th International Conference on Confocal Microscopy

Dear Colleagues,

January 15, 2008, the deadline for abstract submission for the Osaka, Awaji Island FOM2008 conference, is nearing. Please submit your abstract by that date.

Abstracts for oral and poster presentations can now be submitted preferably through the conference website: http://www.FocusOnMicroscopy.org where also the conference registration has opened and hotel booking information is available.

The program for the conference will be finalized and available on our website on Feb. 6, 2008. Authors will be informed individually by E-mail on the placement of their contribution in the program.

After the successful FOM2007 conference held in Valencia in April last year, the next conference: Focus on Microscopy 2008 will take place in Osaka, Awaji Island, Japan from Sunday, April 13 to Wednesday, April 16, 2008. As the next in a series of unique interdisciplinary meetings on advanced multidimensional light microscopy and image processing, the conference will be hosted by the University of Osaka.

Focus on Microscopy 2008 is the continuation of a yearly, well attended conference series presenting the latest innovations in optical microscopy and their application in biology, medicine and the material sciences. Key subjects for the conference are the theory and practice of 3D optical imaging, related 3D image processing, together with reporting on the ever increasing spatial resolutions and sophisticated imaging modes coming available in sectioning microscopy.

The conference series is in addition known for covering the rapid development of advanced fluorescence labeling techniques for the confocal and multi-photon 3D imaging of -live- biological specimens. Laser light in combination with 3D microscopy is starting to play an increasingly important role as a tool at sub-micrometer scales in cell biology for dissection and isolation of structures of interest for subsequent analysis.

Important dates:
Deadline for the submission of abstracts: January 15, 2008
Acceptance of contributions, draft program: February 6, 2008
Deadline for early registration: February 26, 2008

We would like to welcome you to Osaka, Awaji Island for the FOM2008
conference and exhibition. To stay informed about the conference please

Break of JC for Dec holidays

Dear all,

It is almost the end of the year and thanks for the good efforts of participating in this journal club in the past few months. Let's take a break and resume next year!

Cheers,

An interesting paper about -ive refractive index

Lately, we have been discussing about the so called negative refractive index materials (Meta Materials!), an example of which is a super-lens. I found this paper in the Arxiv web site, that negates the whole idea of -ive refraction. Some of you might find it interesting.
Cheers

journal club 29 Nov 2007

Hi all,

For our journal club this thursday (29/11 10.30am pantry),
let's have a discussion on the attached paper, which is related to the other paper I chose the last time.

Thanks,
Wai Teng

Journal club on 22 Nov 2007

Hi all,

It is a new cycle of Journal club again – this week I will be presenting on work that I did during Perth attachment.

“Exploring Fourier Holography for Phase Imaging Applications”


Date: 22 Nov
Time: 10.30am
Venue: pantry area

The location is tentative, maybe I can book the little discussion room in division office but not sure now, and will email again if there is an update.

Regards,

Title: Polarizatio-sensitive full-field optical coherence tomography
Gael Moneron,1 Albert-Claude Boccara,1 and Arnaud Dubois2,*

citation: OPTICS LETTERS / Vol. 32, No. 14 / July 15, 2007
Abstract: We present a polarization-sensitive full-field optical coherence tomography system that can produce highresolution images of the linear retardance and reflectivity properties of biological media. En face images can be delivered at a frame rate of 3.5 Hz by combination of interferometric images acquired by two CCD cameras in an interference microscope illuminated with a tungsten halogen lamp. Isotropic spatial resolution of 1.0
um achieved. The technique is demonstrated on ex vivo muscle tissues.

Journal Club - Mapping polymer birefringence in three-dimensions using a polarizing microscope with oblique illumination

Dear All,

I am going to discuss following interesting paper that talks about measuring 3D distribution of birefringence in the sample. It is interesting in its own right as a basic technique and seems to be a good method of visualizing microtubules during mitosis without any label .

Mapping polymer birefringence in three-dimensions using a polarizing microscope with oblique illumination

ABSTRACT

We have been developing a polarized light microscope with liquid crystal universal compensator and circular polarizer (the LC-PolScope) for recording images, which are independent of the orientation of birefringent objects. Separate images show the retardance and the slow axis azimuth distributions of the in-plane birefringence of the focused region in the specimen. However the measured (apparent) retardance still depends on the angle between the crystal optic axis and the axis of the illuminating beam of light. If the illuminating beam is close to parallel to the optic axis the measured retardance value decreases dramatically and becomes zero when the two axes are parallel. The description of birefringent objects oriented in 3-dimensional space requires the introduction of two additional parameters: the principal retardance and the inclination angle. Together with the azimuth angle they completely characterize the birefringence properties of a specimen, assuming the specimen has a uniaxial optical indicatrix. We devised a new technique for measuring the three birefringence parameters without moving the specimen. For exploring the out-of-plane birefringence the new instrument which is based on the LC-PolScope technique contains an additional spatial light modulator, implemented here as a liquid crystal mask. The mask is located in the aperture plane of the condenser lens. Partial occlusion of the condenser aperture changes the direction of the central ray of the cone of light converging on the specimen. So we can obtain the retardance and azimuth images using different sets of illumination rays. For experimental verification we used a biological object called an aster. An aster consists of nearly parallel arrays of microtubules, a stiff biopolymer, radiating from a common organizing center called a centrosome. The object is spherically symmetric, and its 3 dimensional distribution of birefringence orientation can be predicted. Experimental results have shown the developed polarizing microscope can successfully be used for imaging and measuring three-dimensional orientation of birefringent objects.
