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.

The anti-symmetric modes (A01 mode for low frequency
A 03 mode for high frequency) and symmetric modes (S0 mode) produced by Lamb wave sensor are used to detect multi-parameters of a liquid
such as its density
sound velocity and viscosity. These modes are found to be very different to the parameters. For example
the A01 mode is very sensitive to the liquid's density but the A03 mode is sensitive to its sound velocity. The measurements of the attenuation with S0 mode can give out liquid's viscosity after its density been determined by A 01 mode. That could be a way to distinguish an unknown liquid with high sensitivity or to solve the problem of the selectivity of label free detection on biosensors. 2011 IEEE.

In order to satisfy to the real-time requirement of image interpretation system in photoelectric measurement equipments
a kind of hardware acceleration system with MIMD distributed multi-processor architecture based on SOPC technology is designed. The particle filter algorithm is proposed to process image interpretation for state estimation problem of nonlinear and non-Gaussian system. This algorithm does not involve conventional linearization transform
and has approximated the posterior probability density by a set of discrete particles. Therefore the approximate optimum result is educed. It has a high accuracy and a rapid convergence. Experimental results show that the algorithm be adequate to real time
accuracy and robustness
meets the requirement of image interpretation and possesses practical significance for engineering applications. 2011 IEEE.
