I will discuss fast optical cameras based on the back-illuminated silicon sensor and Timepix ASICs. The sensor has high quantum efficiency and the chip provides nanosecond scale resolution and data-driven readout. The intensified version of the camera is single photon sensitive and has been used in a variety of quantum imaging experiments as well as for other applications such as time-resolved neutron detection and ion imaging. As a motivation for fast imaging in astrophysics I will also review the standard techniques of single-photon amplitude (Michelson) interferometry and two-photon (Hanbury Brown & Twiss) intensity interferometry, and then visit recent ideas for how they can be improved in the optical through the use of entanglement distribution. A proposed new technique of two-photon amplitude interferometry requires spectral binning and picosecond time-stamping of single photons with a product of resolutions close to the Heisenberg Uncertainty Principle limit. I will show recent results and will discuss future directions for the technology.
Prof. Andrei Nomerotski is Senior Researcher at Czech Technical University in Prague and Professor in Florida International University in Miami. He is expert in fast detectors of single photons and their applications in quantum imaging, astrophysics and beyond. He received his PhD in Padua University in Italy in 1996 and later worked in several high profile institutions (Oxford Univeristy, Fermilab and Brookhaven National Laboratory) in leading roles on high energy physics, astrophysics and instrumentation projects.
