Tandem gratings of double-dispersion mount make it possible to design an imaging spectrometer for the weak light observation with high spatial resolution
high spectral resolution
and high optical transmission efficiency. The traditional tandem Wadsworth mounting is originally designed to match the coaxial telescope and large-scale imaging spectrometer. When it is used to connect the off-axis telescope such as off-axis parabolic mirror
it presents lower imaging quality than to connect the coaxial telescope. It may also introduce interference among the detector and the optical elements as it is applied to the short focal length and small-scale spectrometer in a close volume by satellite. An advanced tandem Wadsworth mounting has been investigated to deal with the situation. The Wadsworth astigmatism-corrected mounting condition for which is expressed as the distance between the second concave grating and the imaging plane is calculated. Then the optimum arrangement for the first plane grating and the second concave grating
which make the anterior Wadsworth condition fulfilling each wavelength
is analyzed by the geometric and first order differential calculation. These two arrangements comprise the advanced Wadsworth mounting condition. The spectral resolution has also been calculated by these conditions. An example designed by the optimum theory proves that the advanced tandem Wadsworth mounting performs excellently in spectral broadband. 2012 Optical Society of America.

When the airborne platform
where installed the optical window
is in high Mach flight condition. The aerodynamic heating effect
which will influence optical properties of optical window
becomes very obvious. This special flight condition will change shape
refractive index and also refractive index distribution of optical window due to the generated high axial temperature gradient. To ensure image quality of aerial remote sensor
the present paper does thermal-optical analysis for optical window under high Mach flight condition. Then
on this basis
do simulations according to theoretical analysis and boundary conditions derived from practical assumptions in order to get the final conclusions. 2012 IEEE.

In order to meet the requirement of inertial navigation components and minimizing the system's weight
and topological optimization was conducted. Then
topological optimization and size optimization were conducted under conditions of random vibration and impact. Firstly
according to the dynamic characteristics of missile and requirement of inertial navigation system
the structure of inertial navigation support was designed according to types of missile connection and space arrangement of electronic components
the method of transforming multi-loading cases to multi-loading constraints was used to optimizing the size of the support under conditions of random vibration and impact. Comparing to the original support structures
RMS accelerations in installed points reduced by 25.2% under random vibration
the weight of optimal structures reduced by 28.1%
the structures also met the requirement of inertial navigation system under condition of impact. The support structure shows improvements in both dynamic characteristic and light weight comparing with the original one. 2011 IEEE.

In order to research the attitude algorithm with angular rate input under the conical motion
a optimal threesample rotation vector algorithm based on single-step Newton backward interpolation is proposed. Using the principle of limited rigid body rotation and the characteristic of angular rate input
three-sample rotation vector algorithm is derivated. To minimum attitude errors
three-sample rotation vector algorithm is optimized. Three angular rate extraction methods of singlestep entire sample recursion
multi-step entire sample and singlestep Newton backward interpolation are proposed. Under the condition of conical motion with semi-cone angle 3 and angular frequency 2rad/s
simulation is done. The simulation results show that single-step Newton backward interpolation is superior to the other two methods
and its maximum error peak is 0.01
error drift rate is 0.036/h. Experiments in three-axis flying turntable with the same parameters are carried out
and the results show that error drift rates of three-channels are less than those of traditional quaternion
which are 13.53%
12.08% and 23.68% lower respectively. It also verified that the new algorithm can perform a high accuracy under the conical motion. 2011 IEEE.

The process of parameters design on chisel-edge ruling tool of diffraction grating
which is inefficient and highly costive
needs plenty ruling experience came from a series of ruling test to optimize and design it. In order to reduce the choosing range of experiential design parameters on chisel-edge grating ruling tool
to improve efficiency
and to reduce costs
this paper summarize the experimental results of several gratings ruling process for the experiential design on parameters of chisel-edge ruling tool. Provide the specific parameters choosing range as follows: that the blaze angle and directional angle difference in less than 3
the bottom angle and apex angle difference in less than 5. Apex angle larger than the groove bottom angle in conventional grating
while apex angle smaller than the bottom angle in echelle grating
and the directional angle smaller than blaze angle in both condition. 2011 IEEE.
