June 4, 1997: "Electronic Speckle Pattern Interferometry (ESPI): A Versatile NDT Tool for Deformation Measurements" by Alex Brozeit

Abstract: "Speckle Interferometry " is a generic term for a range of optical configurations that utilize speckle patterns, generated by the interference of laser light scattered from different points on an optically rough surface, to convey information about the object surface. This information can relate to shape or surface profile of an object, the relative displacement under applied load, the vibrational characteristics or the surface strain.

In optical metrology, electronic speckle pattern interferometry (ESPI) provides a proven and powerful deformation measurement technique with sub-micrometer resolution. Since its early days, ESPI evolved into a mature tool for demanding measurement problems. After successful application inside the benign lab environment, ESPI nowadays is establishing as a tool for industrial non-destructive testing (NDT). There are numerous perspective applications where ESPI measurement systems should provide the highest possible amount of ruggedness and compactness as well as flexibility regarding the illuminating system without sacrifice of performance. The utilization of optoelectronic components, fiber-optics and control electronics meets this demand and extends the range of applicability.

Bio: Alexander Brozeit studied Physics at University of Oldenburg, Germany. After receiving his B.Sc. Physics in 1987 he entered the company Spectradata GmbH as systems consultant. His job function included the design and development of non-destructive testing equipment and scientific instrumentation for optical and acoustical measurement. After a joint research project of Spectradata GmbH and the Applied Optics Group at the University of Oldenburg he returned to the University and received his M.Sc. Physics in 1993. Currently he holds a position as a physicist and is involved in research and development of applied optical metrology, like speckle interferometry and fiber-optics systems design.

May 7, 1997: "Light Therapy for Cancer and Cardiovascular Disease" by Mark Ortiz, Pharmacyclics

Abstract: The Santa Clara Valley Laser & Electro-Optics Society will meet May 7. Mark Ortiz, of Pharmacyclics, will be discussing Photodynamic Therapy (PDT), an emerging and promising new approach for the diagnosis and treatment of cancer. PDT is a two step process. A drug is first injected into the patient's body. This is followed by an interval during which the drug circulates, accumulates and is selectively retained in tumors and other abnormal cells, while clearing from most other tissues. The drug does not have any toxic effect on the tumor until it is activated by light at a specific wavelength. Once photoactivated, the drug produces a chemical reaction which destroys the abnormal cells while sparing normal surrounding tissue. Mark will discuss the details of how photodynamic therapy works, including the development of a promising new PDT drug and associated devices being developed by Pharmacyclics, Lutetium Texaphyrin or Lu-Tex.

Bio: Mark V. Ortiz is director of product development for Photodynamic Therapy Products at Pharmacyclics in Sunnyvale. His current responsibilities include the management of the development of Lutetium Texaphyrin, a promising new drug for photodynamic therapy, and associated devices for photodynamic therapy. He received his BS degree in electrical engineering and computer science at the Massachusetts Institute of Technology in 1984 and his MS degree in physics at the University of Oregon in 1988. Mark has over 12 years of experience in the design and manufacture of gas, solid state (high power frequency doubled lasers) and dye laser systems. He currently holds 10 U.S. patents and has published and presented his work internationally.

April 2, 1997: "100 Gb/s All-Optical Logic" by Alan Huang, Terabit Corp.

Abstract: This is the second of a monthly series of distinguished speakers in the field of optics sponsored by the newly reborn Santa Clara Valley chapter of the Lasers & Electro-Optics Society. Meetings will be held the first Wednesday of every month at 7:30 p.m. at San Jose State University. A 6:00 dinner is available for anyone who wishes to meet the speaker. Free parking permits for the SJSU 10th Street garage are available. This month's meeting will be held April 2 and feature a presentation by Alan Huang, of Terabit Corporation and Stanford University. The Sagnac all optical fiber logic gate makes it possible to communicate and process information at faster rates than electronics. The fiber logic gate functions as a two input AND gate, a two input AND gate with one inverting input, or both. It is pipelined with a fixed latency. While originally developed at AT&T, NTT has since used this technology to demonstrate a 200 Gb/s, 100 km communications link. MITI is currently transferring this technology from NTT to major electronics companies as part of its new national Femtosecond Project ($200M over 10 years). Several possible applications will be discussed, including a bit jitter tolerant communications system, an asynchronous communications system, a bit interleaved self-routing switching system, an exchange/bypass permutation unit, and a folded universal state machine.

Bio: Alan Huang was born in San Francisco. He completed his undergraduate and an MS in electrical engineering at Cornell University, and a PhD in electrical engineering at Stanford University. He joined AT&T Bell Laboratories after his PhD, where he worked on signal processing, broadband networks, parallel processing, optical computers, photonic switching, and ultrafast logic. He has worked as a scientific programmer, systems administrator, research engineer, computer consultant, and patent agent. As head of the Optical Computing Research Department, he supervised the development of surface emitting lasers, a pipelined digital optical processor, three dimensional planar optics, intersubband optical modulators, and all-optical fiber logic gates. He has published over fifty papers and has 26 U.S. patents.

March 5, 1997: "The Trials & Tribulations of Building a High-Tech Optics Company" by Milton Chang, New Focus, Inc.

Abstract: Milton Chang will challenge some common views about business - both optics and in general. You may walk away from this talk and immediately jump ship to hang out your own shingle, or strive to become a more effective leader in your current job. He will argue that you can start a business without either a great idea or taking a big risk. He will also discuss the important key ideas for building a successful company.

Bio: Milton Chang is a co-founder of New Focus and Focused Research, and is currently their chairman. He served many years as President and CEO of Newport Corporation. Milton received his M.S. and Ph.D. degrees from Caltech. He is a fellow and a Director-at-Large of the Optical Society of America (OSA).
