With the advantages of small volume
light weight
high efficiency and long lifespan
diode laser has been widely applied to industrial processing. Presently
for laser used as processing light source needs to amount to dozens of KW per cm2 of power density
how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing
808nm laser array composed of 20 bars eventually achieves the 1001.5w power output
coupling efficiency at 90%
11mm2 of light spot through experiments
which enables diode laser to be directly applied to cladding
welding and so on. 2012 IEEE.

Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight
and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem
the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target
the angular velocity of visual axis in inertial space is zero
so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation
the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally
some measures could reduce the dynamic coupling between the framework was given. 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.

Two-axis optoelectronic tracking equipments generally use such mode that azimuth and pitch system are independently controlled. It leads to the two structures completely uncoupled
therefore
and reduces the state space dimension. But the main problem is that the rotational inertia of azimuth is much larger than that of pitch
it is an effective control mode to the two-axis photoelectric tracking equipments.
which leads its dynamic tracking performance is worse. So to find a more suitable mechanics and more effective control strategy is necessary. Considering the tracking ability
this paper designs BMC (bandwidth mutual compensation) to uniformly correct the error of both the azimuth and pitch system in real time
it is realized by cross coupling control to the azimuth and pitch. The simulation result verified that compared with classical uncoupling system BMS not only guarantees the state space dimension but improves systematic tracking performance about 2
