A digital mirror device (DMD) based light projector was developed as the target generator in modulation transfer function (MTF) measurement. In order to overcome the sampling-scene phase effect in MTF measurement of sampled imaging systems  a method using random targets is introduced to yield a phase-averaged MTF. The main potential problem of implementing this method is the fact that the stationary assumption of the random targets may be vitiated in practical measurement  especially in field test due to the ill condition. We provide an efficient model-independent way of analyzing and isolating the spectral contents arising from these additional contributions to MTF measurement. Algorithms with adaptive parameter selection were also developed for spectral estimation of the test image in order to overcome the challenge brought by the size limit of the test matrices for one certain field of view derived from the isoplantic region. The MTF measurement of a CCD video imager is used to demonstrate the measurement technique and illustrate the benefits over other methods. In order to validate the results  comparisons have been made between MTF measurements of imager implemented using this method and bar target direct measurements. 2010 Copyright SPIE - The International Society for Optical Engineering.  
Semi-physical simulation of an optoelectronic tracking servo system based on C MEX S functions (EI CONFERENCE) 会议论文  OAI收割

To the design of an optoelectronic tracking servo system  we test the method [1  not only the reasonability of the control algorithm should be considered  2]. The simulation results verify the theoretical analysis. Because C MEX S function has the features of fast execute speed  but the cost and time as well. It is necessary to establish the simulation model for the system. Applying the C MEX S functions  independently generated program  we can build the every independent digital control modules in MATLAB/SIMULINK for the optoelectronic tracking servo system. In the paper  directly download to the hardwires  we apply the C MEX S function to the design of the practical optoelectronic tracking servo system. For the speed  we can design and debug the digital control modules in MATLAB/SIMULINK and then transform and download directly to DSP processor. 2010 IEEE.  position loop control and TV delay compensations

Application Research of Intelligent Algorithm in Electric-driven Flight Simulation Turntable is discussed in this paper. Fuzzy control is used to solve the problem of fast tracking and overshoot since its essence belongs to PD control In order to improve the performance of system in low speed  a method named variance-gain adaptive algorithm is introduced in this paper. It defines the amplifier gain as a function whose independent variable is speed  so the amplifier gain can automatically be adjusted with the change of speed. When the turntable runs at low speed  it has a big amplifier gain  a good rigidity and high tracking accuracy. When the turntable runs at high speed  the method can control the amplifier gain and ensure the system dynamic performance. Design and implementation of these algorithms is introduced in detail. Experiment results show that the Flight Simulation Turntable has achieved the required performance through using fuzzy control algorithm and variance-gain adaptive algorithm. 2008 IEEE.
