The solar irradiance monitor (SIM)  with the design accuracy of 5  used to monitor the secular changes of the total solar irradiance on FY-3 satellite  takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method  this method simplifies the structure and cuts the cost  but the measuring accuracy is affected by the sun-synchronous orbit  sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment  studies on the affection of different sunlight incidence angles to the measurement accuracy. First  by the satellite tool kit (STK) simulation software  simulates the orbital parameters of the sun-synchronous satellite  and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite  and base on the components designs the field of view and the installing angles of the SIM. Then  designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis  measures the total solar irradiance by the SIM at each angle  and compares to the irradiances of the SIAR reference radiometers  and gets the coefficient curves of the three channels of the SIM. Finally  by the quadratic fitting  gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302  R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance  and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.

The opto-electronic platform is the main equipment for aviation reconnaissance. It is a surveillance system with the function of search  recognition orientation and tracking by opto- electronic instruments. It is made up of opto-electronic instruments which are used to get high quality image  and stabilization tracking system to control stabilization and gesture of platform for exact tracking. The opto-electronic platform purpose is to achieve high quality image. Besides the impact of optic system  the image quality of the system is influenced greatly in the vibration environment. The research worked by Zhao peng which demonstrated the affection caused by angular vibration was worse than which caused by line vibration  and what was multiplied direct ratio with plane altitude. So it is necessary to design a new device which could be used widely and has good angular vibration isolation effect. According to the theory of parallelogram  the non-angular vibration device had been designed with spatial links  and the theory of non-angular vibration was analyzed. The three-dimensional model was set with UG  the analysis was done by ADAMS/vibration software. The acceleration and displacement response of the device in each direction was calculated by inspiriting it with sine wave of the acceleration in three directions  and the stiffness and damp were studied. All the work prove the design principle of the device is reasonable  and the device is adopted to keep the platform motion moving horizontally  at the meantime the device is good at isolating vibration in all directions. 2010 SPIE.

In the device  a He-Ne laser of flash frequency 1-20 Hz was adopted as exciting light source  and three key technical problems have been solved successfully in order to enhance the detecting sensitivity and measuring stability of the device for time-resolved fluorimmunoassays(TRFIA) [1]. The first one is to design optimum exciting optical system  so that the exciting light beam excite the sample most effectively. The second one is to have a project spectrum filter which can reduce the affection of the background light to the photomultiplier tube and also ensure influence of the stray light and mixed diffusion light to the sample fluorescence to the least  the sample fluorescence through the integrating sphere and come to the grating monochromator  The right wavelength will be chosed through changing the angle of incidence of the grating monochromator. The third one is to simulate the principle of sample averaging of BOXCAR averager. In the device  SCM was used as primary controller and CPLD was used as timing controller. Through the preparation process  signal-to-noise ratio(SNR) will be improved  also adjust delay time  ampling frequency and sampling number arbitrarily. By testing  the sensitivity is 10-12mol/L(substance marked by Eu3+)  examination repeat is &le2.5%  examination linearity is from 10 -8mol/L to 10-12mol/L  correlation coefficient is 99.98%(p&le0.01). The instrument is advanced for ultrasensitive detection of antigen and antibody  and solve the tumor  genetic variation  the virus protein detection. 2009 SPIE.
