In order to further enhance the bandwidth of the data communication system in theodolite
The whole design of the PMD is realized by using Xenpak optical module. Its duty is responsible for converting 4-channel parallel 3.125Gbps data stream into a serial 10.3126Gbps data stream
a single channel serial optical transmission system was designed based on the studying of the 10BASE-X Gigabit Ethernet physical layer technology which meets the IEEE standard. The conversion between the 64-bit 156.25MHz TTL signals and the 4 channel 3.125Gbps PCML differential signals is carried out by FPGA
and sending out it in the form of light signals. The experimental results show that data transmission capacity was achieved a 10Gbps in the single-channel optical transmission system. It can conduct short distance transmission. The system delay is about 31lns. The bit error rates no more than 10-12
which satisfies the system demand. 2010 IEEE.

In order to put the parallel one-way hash function into engineering
two designing models based on pipeline technology are proposed in this paper. The definition of one-way hash function is shown first
and the structure and limitation of the current hash functions are discussed afterward. By analyzing the difference between parallel computation on different platforms and classifying one-way hash functions on application basis
the possibility and method of parallel one-way hash function designing on different hardware platforms are described
two designing models are constructed for the parallel one-way hash function designing. Finally
some attentions for designing are proposed from the engineering angle. The pipeline models that proposed in this paper contact the theoretical rationality and the engineering application of parallel one-way hash function together
which can improve the practicality of parallel one-way hash function to a great extent. 2010 IEEE.

A key problem of attitude measurement of small-multi-target with high speed is how to decide the optimum of the CMOS stations. A multi-CMOS station mode is designed in this paper
multiple CMOS videos were placed on two parallel sides in measurement system
every two CMOS form an intersection viewing field
multiple viewing field join to cover shooting range
which can augment Effective Viewing Field(EVF)
increase capture ratio of objects with high speed and measurement precision of small objects. When an object passes through the joint area
it will be imaged separately on each CMOS focal plane. Multiple CMOS videos were triggered synchronously
a sequence of image information was extracted
the target attitude was confirmed by digital image processing technology. The merit of station mode is low cost
large measurement scope
extending freely and so on. 2010 IEEE.

This paper describes a kind of automatic test technology of the parameters used in a dual-CCD TV measure-system (TV -MS) .The TV -MS is the ground control equipment of the anti-tank missile and integrates the technologies of optical
machine and electronics. It is important and key component. The main technical parameters of the TV -MS are field of view
zero point
precision
sensitivity
anti-jamming ability
zooming time and focus time
etc. To insure the TV -MS satisfying the tactical and technical requirements and discover fault and reason
a fast and accurate equipment satisfying the test technical parameters of the TV -MS is urgently needed in manufacture and service. Firstly
the parameter test system converted optical signal to electronic signal
implemented automatic control of the invariant illumination of parallel pipeline output. Secondly
data and command delivering
displaying or printing are realized by using 80C196KB. The experiment result shows that the approach of automatic testing of the Parameters used in a dual-CCD TV -MS is successful and it can be used for all tests of the functions and parameters of the TV -MS. The main innovations are to realize the fast
veracious measure of technical parameters of the dual-CCD TV-MS
and integrate the technologies of optics
machineries and electronics. An advanced means is provided to judge the technical states
find malfunctions and discover the reasons in producing and maintaining process. The equipment suited for anti-tank missile systems is given.

Star sensor is a special high accuracy photoelectric sensor. Attitude acquisition time is an important function index of star sensor. In this paper
the design target is to acquire 10 samples per second dynamic performance. On the basis of analyzing CCD signals timing and star image processing
a new design and a special parallel architecture for improving star image processing are presented in this paper. In the design
the operation moving the data in expanded windows including the star to the on-chip memory of DSP is arranged in the invalid period of CCD frame signal. During the CCD saving the star image to memory
DSP processes the data in the on-chip memory. This parallelism greatly improves the efficiency of processing. The scheme proposed here results in enormous savings of memory normally required. In the scheme
DSP HOLD mode and CPLD technology are used to make a shared memory between CCD and DSP. The efficiency of processing is discussed in numerical tests. Only in 3.5ms is acquired the five lightest stars in the star acquisition stage. In 43us
the data in five expanded windows including stars are moved into the internal memory of DSP
and in 1.6ms
five star coordinates are achieved in the star tracking stage.
