Title: Countermeasures of stealthy cyberattacks: From a system and control perspective
Abstract: It has been over ten years since the Stuxnet virus intruded into and caused actual damages to the real-world industrial facilities. While it was a big shock to the industry worldwide and raised significant concerns in safety and security, such novel types of attacks to industrial cyber-physical systems have been extensively studied in recent years. In this talk, we will dive to the monitoring and control level of industrial systems and explore the mechanisms of cyberattacks to control systems. Especially, I will explain about the design principles of stealthy attacks and some typical countermeasures to defend such threats, in terms of prevention, detection, and mitigation.

Title: Tunable mid-infrared detail-enhanced imaging with micron-level spatial resolution and photon-number resolving sensitivity
Abstract: The underdevelopment of mid-infrared (MIR) components and detectors greatly limit the spatial resolution and sensitivity of MIR imaging. To overcome these limitations, we actualize MIR detail-enhanced imaging via non-degenerate optical parametric amplification (OPA) pumped by a femtosecond vortex pulse. This design renders MIR illumination into a visible image by nonlinear wavelength-conversion, together with a high OPA gain, large spatial bandwidth and remarkable sensitivity. Our experiments show, to our knowledge, the first realization of a non-scanning MIR imaging with a spatial resolution of up to 114 line pairs per millimeter and a two-dimensional spatial bandwidth product of up to 62900, over a spectral region tunable from 2.0 μm to 3.0 μm. Equally important, this setup has simultaneously achieved excellent imaging sensitivity of 25 photons at room temperature. We think that this work provides a powerful way to realize effective real-time MIR imaging with an excellent spatial resolution even in very weak illumination environments, which can benefit many applications from semiconductor material characterization and biomedical imaging to security.
