A comparison study on temperature measurement precision between middlewave 3-5m and longwave 8-12m measuring thermal imaging systems has been conducted. The study was limited to systems working in indoor conditions and the target's temperature is in the range of 270K900K. First
the Disturb Resisting Function (DRF) of infrared systems is deduced. On the base of DRF curve
we find that the middlewave infrared system get the smaller influences under the same size disturb compared with the longwave system. A theory of the influence of target's physical characteristic and measurement conditions on the accuracy of temperature measurements has been developed. On the basis of the developed formulas an analysis of the influence of signal disturbances (because of incorrectly assumed emissivity
limited transmittance of the atmosphere
radiation reflected by the object and shift of optics radiation) on the accuracy of temperature measurement has been made. It has been found that the middlewave systems in typical temperature range offer generally better accuracy in temperature measurement than the longwave ones do. 2012 IEEE.

YF3: 20%Gd3+
20%Yb3+
0.5%Tm3+ nanocrystal has been synthesized by a hydrothermal method. The upconversion (UC) emission and energy transfer progresses between Gd3+-Yb 3+-Tm3+ under a 980-nm continuous wave semiconductor laser diode excitation have been explored. The experimental results show that the violet and ultraviolet (UV) enhancement with Tm3+ upconversion emission occurs in the nanocrystal
and in the same time the UC emissions of Gd3+ from 6D9/2
6IJ
6P5/2
and 6P7/2 states to the ground state 8S7/2 are obtained
too. The dynamic analysis implies that
under 980-nm excitation
the nanocrystal dimension plays a key role in the efficient energy transfer processes between Gd3+-Yb 3+-Tm3tt based on the energy matching conditions. 2011 Published by Elsevier B.V.

Studied the transient thermal transfer analysis method due to a kind of supersonic ellipsoidal dome
which is a conformal dome. Illuminated the principle of transient thermal transfer analysis. Accomplished the transient thermal analysis based on the model of ellipsoidal dome
and studied the influence about the different material and the different velocity. Considered three materials consist of MgF2
Al2O3
and ZnS
and meanwhile
the velocity was Mach2.5
and the time consists of 10s
20s and 60s. The temperature initial loads were from FLUENT thermal simulation. The thermal conduction analysis and the thermal convection analysis were finished in software ANSYS
in which the entire transient thermal analysis consists of modeling
meshing element
calculating and getting the results. The different temperature distributions based on varied time were gotten about the different materials. The results from analysis showed the temperature distribution of the structure of ellipsoidal dome
which could help the following coupled thermal-structure analysis. 2011 IEEE.

In order to design and manufacture more excellent airborne photoelectric stable turret
modulus of elasticity of 213 GPa and thermal expansion coefficient of 7.9106/K. The frame has decreased the maximum deformation by by 60% and increased the fundamental frequency by 65% as compared with those of aluminum alloy materials
a new type of aeronautical material-particulate reinforced aluminum matrix composite (SiC/Al composite) is investigated. Several crucial technologies
respectively as shown by finite element analysis results. Those are confirmed by vibration test furthermore. Therefore
such as pressureless infiltration technology
a significant lightening effect is achieved and the thermal control load is also reduced. The test result indicates that the stable accuracy of the system achieves 19.8rad and the optical-axis parallelism of pay load is 0.1mrad. The research applies the SiC/Al composites to airborne photoelectric platforms
interface reaction controls and plate's welding are systematically studied. Then
which makes a effective exploration for the new aeronautical material's application. 2011 IEEE.
using SiC/Al composites
the airborne photoelectric stable turret frame is successfully prepared in density of 2.94 g/ cm3

In order to realize autostereoscopic 3D projecting display with higher brightness and larger size
a technique of autostereoscopic 3D projecting using parallax barriers and lenticular sheets is proposed.The parameter design of lenticular sheets and parallax barriers is investigated.First
projection distance of projector array is confirmed according to eye's resolution
then the strips' character of lenticular sheets is analysed by zemax in four-view situation
thickness and parameters of strips of lenticular sheets are confirmed. Finally
the width of slit and pitch and viewing distance and etc of parallax barriers are confirmed according to parameters of strips of lenticular sheets.Data analysis indicate that the brightness of our four-view image is increased three times because of using lenticular sheets instead of parallax barriers comparing with the autostereoscopic 3D projector using two parallax barriers plates.Parameters design of parallax barriers and lenticular sheets are finished
the feasibility and advantages of the 3D display of projecting are confirmed theoretically. 2011 IEEE.

A non-linear light-of-sight(LOS) locating compensation algorithm for certain aerial remote sensor is presented in this paper. The LOS locating system is composed of two main components
which are an inertial reference frame to provide coarse LOS locating and a 2-axis Fast Steering Mirror to remove the frame's residual error. The azimuth and elevation of LOS are both affected by the FSM two-degree-of-freedom rotation
which should be dealt with to raise the accuracy of LOS location. This paper extrapolates LOS locating algorithm of FSM by coordinate transformation
and gives corresponding deviation analysis for different LOS poiting angles. It is found that the angle deviation grows rapidly with range of FSM's travel enlarging
so the deviation must be eliminated. Through the data analysis for deviation
a non-linear compensation algorithm is proved effective to reduce the error of LOS significantly. Taking LOS changing in [-3 deg
3 deg] as an example
two analytic expressions are given
and the LOS locating accuracy rises by 34 times compared with non-linear compensation unused
and the cross coupling of LOS loating is 0.08%. 2011 IEEE.

In order to solve the conductive ring module's interference problems
measured the electromagnetic radiation of Power drive module
and used test results analysis the electromagnetic compatibility of the conductive ring
identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working

from the electromagnetic radiation theory
the paper analyzed the electromagnetic radiation of the power drive module. From it
determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results
calculate the interference voltage of wire in Conductive ring
and then determine the corresponding EMC method. The results show that
when The power drive module Radiate Electromagnetic waves
wires would coupled common mode interference voltage
its frequency is 3MHz

it would interfered the operation of sensor. By reducing the area of ground loops
used shielded cables
final rule out the interference. 2010 IEEE.
