Lab News

Conference: Ali, Zac, and Jimmy presented their work at Photonics West, in San Francisco from 12 to 18 February. Congratulations to all three on a job well-done on measuring acoustic radiation force, structured illumination with random patterns, and collagen fibril orientation, respectively. Conference proceedings will be available in a few weeks.

Alumni News: Will Goth now at University of Texas, also presented an excellent talk on his work imaging heart valve fiber structures with polarized spatial frequency domain imaging.

Jobs: Ali is working on an internship at Ninepoint Medical this term. Si is on a cooperative education assignment in electronics at a company in Lowell. Congratulations to both.

Welcome to the Optical Science Laboratory (OSL) at Northeastern University. Led by Associate Professor and author of Optics for Engineers, Charles DiMarzio, the OSL is one of the laboratories affiliated with the department of Electrical and Computer Engineering, the department ofMechanical and Industrial Engineering, the newly-formed department of Bioengineering, and the Gordon Center for Subsurface Sensing and Imaging Systems, at Northeastern University. The OSL is particularly interested in those imaging techniques that involve optics (especially coherent detection), multi-modal imaging where light is used in combination with another type of wave such as microwave or ultrasound, and hyperspectral imaging.

Equipment includes the W.M.Keck 3-D fusion microscope combining brightfield, phase, DIC, confocal, multi-photon, and harmonic microscopy on a single platform. With a high-speed rotating polygon scanner, frame rates of 10 Hz. are achieved. We also have a separate microscope for quantitative phase imaging, a line-scanning confocal reflectance microscope, a structured-illumination breadboard, and a dual-galvo scanning microscope. A dual-channel tissue spectrometer is used for imaging hemoglobin and other chromophores in tissue such as skin, muscle, and bone.

Our applications include mostly biological and medical imaging, with specific intersts in melanin imaging, ex-vivo alveolar-scale lung imaging, bone hemoglobin spectroscopy, corneal collagen imaging, dermatology and deep penetration of light using an ultrasound guidestar for phase conjugation.

OSL's goals are to provide a facility for advanced research in these areas in order to address the needs of our research sponsors, and to train the next generation of researchers for industry, academia, and the government.
