Real-time, continuous-wave terahertz imaging by use of a microbolometer focal-plane array.
Real-time, continuous-wave terahertz imaging is demonstrated with a 10 mW, 2.52 THz (118.8 microm) far-infrared gas laser and a 160 x 120 element microbolometer camera. The microbolometer camera is designed for wavelengths of 7.5-14 microm but retains sensitivity at terahertz (THz) frequencies. The setup has no moving parts, and transmission-mode THz images can be obtained at the video rate of ...
متن کاملP5.11 Application and Design of Satellite Infrared Spectral Imaging Radiometers with Uncooled Microbolometer Array Detectors
Uncooled array detectors offer a number of advantages for space borne infrared array imaging. The elimination of detector cooling requirements can significantly reduce the size, cost and power requirements systems. Integration of the instrument to a spacecraft is much simplified due to reduced thermal management requirements. An array of detectors permits imaging without mechanical scanning. In...
متن کاملUncooled Infrared Radiation Focal Plane Array with Low Noise Pixel Driving Circuit
We have analyzed the dominant noise sources in the driving circuit of an uncooled infrared radiation focal plane array fabricated on a silicon-on-insulator (SOI) substrate by 0.35 μm CMOS technology and bulkmicromachining. We found no noise property of SOI-MOSFET inferior compared to those of NMOSs formed on SOI and bulk substrate, respectively. In addition, we reduced the total noise of the se...
متن کاملTHz Imaging Using Uncooled Wideband Direct Detection Focal Plane Arrays
In millimeter and submillimeter-wave radiometric imaging systems, a persistent goal is the increase in the speed of acquisition of the image while maintaining a high sensitivity. Typically, the highest sensitivity is achieved by cryogenically cooling the detectors, specifically in astronomical applications. However, for the purpose of low-cost imaging applications, it is desirable to operate at...
متن کاملReal-Time Imaging Using a 4.3-THz Quantum Cascade Laser and a 320 240 Microbolometer Focal-Plane Array
We report the use of a 50-mW peak power 4.3-THz quantum cascade laser (QCL) as an illumination source for realtime imaging with a 320 240 element room-temperature microbolometer focal-plane array detector. The QCL is modulated synchronously with the focal-plane array for differential imaging. Signal-to-noise ratios of 340 are achieved at a 20-frame/s acquisition rate, and the optical noise equi...
