Designed and built control system for a 5-line laser imaging system. This allows fine grained control over illumination time, polarization and acquisition time. High frequency frame acquisition in the 20-30 ms range. Built to facilitate live imaging FRET experiments.
Using 3D Printed Molds
Designed & 3D printed mold for creating waveguides from optical polymers.
3D printed molds
Optical polymer in negative PDMS mold
Mach-Zehnder Interferometer from an optical polymer
Wrote an open-loop path tracking algorithm for a wheeled robot
equipped with a camera. Success with sharp turns and intersecting
paths. RaspberryPi & Python scientific stack.
Solving Systems of Constraints Symbolically
Demonstrated the use of a SMT solver (Z3, Microsoft Research) to
recover secret information from a pseudorandom number. Approach
demonstrated as a detector for weak RNGs in web applications.
