The breast is scanned by stepwise positioning of source and detector, and amplitude and phase for both wavelengths are measured by a photomultiplier tube using heterodyne detection. Images are formed representing amplitude or phase data on linear gray scales. Furthermore, various algorithms carrying on...
A Frequency Domain Infrared Superconducting Transmission Line (FIRST) detector is comprised of a folded superconducting transmission line 18 coupled at an input port 18a to a narrow band microwave source and coupled at an output port 18b to a microwave power monitor 22. An optically induced change...

The reason for the dimensionality reduction is that (1) qDSA only analyzes signal along the centerline of a vessel, and (2) each pixel along the centerline represents an average signal along the line projected from the X-ray source to the detector pixel. Thus, only points within a plane ...
detector once during the complete analysis program. The total program processing time can be short compared to the epoch of the signal. For instance, a typical time duration for the input signal is 40 milliseconds and the time to next service is 45 milliseconds. With 4K samples per second, ...
The derived detector is a correlation-limiter in frequency domain. The simulation proves its performance, and indicates its mechanics of frequency selection. 展开 关键词: electronic warfare emitter identification specific emitter identification robust hypothesis testing time-variation channel ...
