Reliable Detection

AbstractA prototype of a spectral imaging module is described which can be attached to conventional rigid and flexible medical endoscopes. It is based on acousto-optic tunable filters (AOTF) and provides fast spectral image registration at an arbitrary series of wavelengths. The main advantage of the device is the minimization of spatial and spectral image distortion by use of a specialized double AOTF monochromator. These properties ensure immediate and reliable detection of spectral features in any image pixel. Real-time spectral analysis, in addition to spectral visualization, provides the opportunity to make medical photoluminescence diagnostics more effective.

New Generation

In order to achieve real-time data output in synthetic aperture radar (SAR) imaging system, high-speed FFT transformation is needed. In this article, we proposed the program that uses the new generation of high-speed, large-capacity Virtex series FPGA to implement radix-4 FFT algorithm and simulated it with the Modelsim software, and then through the comparative analysis of simulation results by MATLAB. After analyzing the results compared with MATLAB simulation, it shows that FFT module has stable performance, fast operation and fully meets the radar data real-time processing requirements.
