The television imaging system of steady platform is designed by applying optical zoom lens principle and array CCD image collecting technology in this paper. The system is a crucial component of steady platform to come true tracking capability. The paper expatiates working principle and its key technology.
This paper studies testing technology of photoelectrical transmittivity, analyses the reason of error occurred in testing system, and find out the method for resolving it. It is high automation and accuracy than traditional methods. The system uses parallel light-pipe as lamp source, which is revised by correction filter, to obtain the white light of approaching visible spectrum trait. The white light is divided into two lights: reference light and measuring light. Reference light is coupled to modulator by optic fiber coupling device, modulator turns it into fixed frequency light and then it enters integral ball through ancillary lens. After measuring light passes by testing-piece, it is assembled to modulator by collector lens, modulator turns it into particular frequency light and then it enters integral ball through ancillary lens. The lights diffused reflection heaps of times in integral ball become the equality lights and are in proportion to flux of incidence. Electric eye converts light signal to electric signal. The electric signal contains two frequency signals, it is magnified by synchronous amplifier, and at last gains the electric signal in proportion to the light from pupil.
The precise of artillery duplicate-aim is the important tactics index. At present many countries are making great efforts to improve the firing rate of large artillery, and the leading index of artillery in high firing rate is duplicate-aim precision. So the measure of duplicate-aim precision of artillery and evaluation of reliability are very crucial. The paper proposes a Theodolite front across-assembling method with cooperative object by which the precise of artillery duplicate-aim is non-touch detected. According to the precise demand of artillery duplicate-aim, the optimal disposition theory of theodolite front across-assembling is presented to assure high system precise. It proves that the method function with simpleness and high detecting precise and better flexibility and acclimation.
