Abstract

A technique of fiber array structure of visible to infrared image transducer for infrared imaging control and guide was discussed. Be different from the normal fiber array, the structure here is micro-fabricated on quartz glass covered with visible absorb member in front of the fiber. The fiber array structure works in vacuum and cooling chamber. The 3D model of fiber array structure for finite element analysis based on the secondary radiation was established. The material parameter, including density, specific heat and thermal conductivity, and the structure size including section size, length of fiber array transducer for temperature and time character were studied. The simulation results show that the thermal conductivity and length of fiber array are key parameters for transducer's property, and the optimized parameters for fiber array structure transducer were given. The fiber array structure of visible to infrared image transducer has the advantage of higher spatial and temperature resolution, and less manufacture cost. The optimized parameter for fiber array visible to infrared image transducer can reach the frequency of 100Hz and higher temperature of 250°C in case of increasing impulse power which can be used as infrared scene projector in hardware-in-the-loop simulation experiment.
