The paper discusses the hardware implementation of the quad sensor structure and the possibility to improve the noise characteristics of the structure when simultaneously sampling is accomplished. The histograms of the linear and angular accelerations are given to proof the theory of the structure, published in our previous paper. This structure may be manufactured as a single MEMS inertial sensor...
Modern mixed-signal/RF circuits with digital calibration capabilities could achieve significant performance improvements once the calibration process is completed; however, the calibration time is often very long - in the order of hundreds of milliseconds or even seconds. As testing such devices would require completion of calibration first, lengthy calibration time would result in unacceptably long...
According to the specified standard of airborne Photogrammetry, digital airborne cameras must have higher performance than ordinary civil cameras, which must shoot with shorter time interval and will generate huge data stream. In this paper, a digital airborne camera is designed and implemented in a single FPGA chip as a SOPC approach. The functions of image acquisition, storage and display are implemented...
