Military Application of Differential FTIR Radiometry for Passive Standoff Detection
For the past six years Defence R&D Canada – Valcartier has been developing a method for the passive remote sensing of chemical vapours by differential Fourier-transform infrared (FTIR) radiometry. The originality of the method lies in the use of a double-input beam FTIR spectrometer (CATSI) optimized for optical subtraction. This configuration automatically reduces the clutter-to-signal ratio a...
متن کاملEquivalent system for a multiple-rational-order fractional differential system.
The equivalent system for a multiple-rational-order (MRO) fractional differential system is studied, where the fractional derivative is in the sense of Caputo or Riemann-Liouville. With the relationship between the Caputo derivative and the generalized fractional derivative, we can change the MRO fractional differential system with a Caputo derivative into a higher-dimensional system with the s...
متن کاملA Passive Wireless Temperature Sensor for Harsh Environment Applications
High temperature sensors capable of operating in harsh environments are needed in order to prevent disasters caused by structural or system functional failures due to increasing temperatures. Most existing temperature sensors do not satisfy the needs because they require either physical contact or a battery power supply for signal communication, and furthermore, neither of them can withstand hi...
متن کاملDielectrically-Loaded Cylindrical Resonator-Based Wireless Passive High-Temperature Sensor
The temperature sensor presented in this paper is based on a microwave dielectric resonator, which uses alumina ceramic as a substrate to survive in harsh environments. The resonant frequency of the resonator is determined by the relative permittivity of the alumina ceramic, which monotonically changes with temperature. A rectangular aperture etched on the surface of the resonator works as both...
متن کاملNoise-equivalent sensitivity of photoacoustics.
The fundamental limitations of photoacoustic microscopy for detecting optically absorbing molecules are investigated both theoretically and experimentally. We experimentally demonstrate noise-equivalent detection sensitivities of 160,000 methylene blue molecules (270 zeptomol or 2.7×10-19 mol) and 86,000 oxygenated hemoglobin molecules (140 zeptomol) using narrowband continuous-wave photoacous...
