System Engineering for the Reticle Stage group involved in the development of a stage capable of subnanomenter precision for an Extreme Ultraviolet Lithographic tool [13 nm] that will be brought to market by mid 2010.  Responsible for the System Engineering requirements for 4 sections of this Reticle Stage. Engineering activities included tolerance studies, Machine and Material Damage network layout, system design, documentation and debug during system integration. Also wrote calibration and performance code in python. 

Architected a LabVIEW software program to control all aspects of a complex Production Test Stand used to build, trouble shoot and analyze performance of a Semiconductor Wafer Alignment Sensor currently used in Ultraviolet Lithographic tools. Program was architected to be scriptable so that scripts could be queued up to capture data, analyse the data and create reports. System included 4 data acquisitions boards, a Scope board, 5 image acquisition systems, 6 axis motion control system, 4 lasers, a metrology system as well as a many optical instruments. 

Involved in the System Engineering and LabVIEW software development to build an instrument used to evaluate novel Spatial Light Modulators [SLM] with micron size mirrors intended for use in a Optical Maskless Lithographic tool. This instrument was used to calibrate and measure performance for SLM submitted to the client for evaluation.   

Project Part of a team that engineered and built prototype and production units of a Surface Plasmon Resonance capable of measuring protein binding statistics of 400 samples on a single square inch grating.    Responsible for software development as well as  prototyping the optical, mechanical, and fluidic systems in these instrument. Data measurement and processing techniques were developed.

Leader of a team that designed and built Phase Fluorometer instruments to measure lifetimes of biological probes and specimens.  The configuration of these instruments includes a portable unit with elliptical optics for measuring lifetimes in Phytoplankton, a unit for lifetime analysis of biological probes on microscope slides, as well as a fiber-optic unit to read 96 and 384 well microtiter plates.  These instruments utilize a heterodyning technique to measure lifetimes accurately to less than 20 picoseconds.  The excitation sources are either LEDs or laser diodes modulated at frequencies from 10 up to 100 MHz.

Prototyped and built a Fiber Optic Raman probe utilizing a Quartz Acousto-Optic Tunable Filter (AOTF) and Photomultiplier Tube (PMT) as the spectrometer which allows rapid scanning in key spectral bands. Holographic beamsplitter and notch filters are used to filter out the strong Raman signal from the excitation fiber.

Prototyped and built the components for the optical portion of an Automated Fluorescent Imaging microscope.  The system consisted of a visible AOTF, Intensified Video camera and long working distance microscope objective.  In addition, also responsible for building a Fluorescent Imaging microscope utilizing a TE Cooled CCD camera.

Research done in developing a Tunable Photorefractive Holographic Filters.  The Phase 1 used Four Wave Mixing to investigate the possibilities of a tunable notch filter whereas the Phase II used two beam coupling to create a tunable coherent-incoherent filter.  Work on this project was done in conjuction with the University of Rochester.

Designed and prototyped a Color Analyzer Spectrometer which is capable of measuring process color ink densities on Web presses at speeds of up to 500 m/min.

Built an instrument capable of picomolar fluorophore detection utilizing an Ar⁺ laser, fiber optics, microscope objective, and an AOTF and solid state PMT as the spectrometer.

Prototyped rigid and flexible fiber optic and video borescopes used for remote imaging and sensing.
