Sapphire Fiber Optic Sensor for High Temperature Measurement
… souceless sensor, the simple Fabry-Perot (F-P) interrogator, and the sensor system. Chapter 1 briefly reviews the background of thermal radiation, fiber optic F-P sensors, and F-P signal demodulation. The research goal is highlighted. In Chapter 2, a temperature sensing system is introduced. The …

Design and Implementation of a Secondary Surveillance Radar/Identification Friend or Foe Transceiver Card
… SSR/IFF equipment, i.e. the transponder or the interrogator, can be tested by means of an SSR/IFF test set, which is usually extremely expensive, hard to transport and requires end-user certificates. This dissertation thus focuses on the design and implementation of a short-range real- time …

Route Validation Using Radio Frequency Identification
… transponders are permanently installed while the interrogator is affixed to a person or object that travels the course. Data are collected by the interrogator and can be examined later to derive path taken, distance, and time. The technology can also be adapted for use in a loosely-connected …

Observers' Perceptions of Rapport in Accusatorial Interrogations
… self-incriminating information, rapport enables interrogators to gain the suspect’s trust, respect, and cooperation. Although the specific psychological mechanisms by which rapport achieves these effects are largely understudied, rapport-building techniques resemble principles of social influence …

Location estimation in a 3D environment using radio frequency identification tags
… width including of the wake up signal of the interrogator, travel time between the interrogator and tag, and the tag's response was measured and quantified. It was observed that the width of the signal was proportional to the distance between the tag reader and the tag. It was noticed that the …

Strain sensor using fiber bragg grating interrogation
… a fully portable, low-cost and low-powered interrogator which is specifically designed to read FBGs within the C-band. An optical strain sensor utilizing reflected light of FBG as input to sagnac loop filter (SLF) is experimentally demonstrated in this work. The proposed SLF has been …

Resonant cavity Fibre Bragg grating sensor interrogation
… of a commercially viable optical sensor interrogator based on the resonant cavity architecture forms the remainder of this thesis. A fully programmable SOA drive system allows interrogation of sensor arrays 10km long with a spatial resolution of 8cm and a variable gain system provides …

Artificial perceptions : biases, fictionalities, and signifiers
… Game, allowing the reader to take the role of "interrogator" within this thesis. I use Turing as the foundational premise for the various experiments of my own design in the thesis. It concludes with a performance between all agents in this thesis, including the committee, the algorithms, and …

RFID technology
… capacity. RFID system mainly consists of interrogator (reader) and transponder (tag) and it is allocated in different bands of frequencies (Lower, high, ultra high and microwave bands). There are three types of RFID systems which are divided according to these bands of frequencies. RFID …

Development to a Flexible Surface Acoustic Wave Sensor for Strain Sensing
… radio frequency signal is passed through an interrogator to the antenna connected to the input transducer which transfers the signal in the form of Rayleigh waves. The frequency response of the SAW device changes in amplitude and phase when subjected to temperature, pressure, or strain …

Nanopower Analog Frontends for Cyber-Physical Systems
… that uses energy scavenging to determine if an interrogator is within range before transmitting. A multi-year deployment of this sensor frontend for structural health monitoring is currently active on the Mackinac Bridge in northern Michigan and demonstrates successful transition from laboratory …
