The energy measurement result of high-energy laser is influenced greatly by heat loss as the laser pulse duration is very long. The effect of heat loss, including heat radiation, thermal conduction, heat transfer, on energy measurement result of long pulse high energy laser is studied in this paper. The corresponding data processing model is given to correct the measurement result. An experiment setup is built up. The result shows that the measurement uncertainty will be reduced greatly by data processing.
A modular Infrared simulation test system has been developed for laboratory testing of a kind of UUT with Infrared (IR) sensors. This paper mainly focuses on the software development for the system. The software for the system is divided into two parts, i.e. the main control computer software and image generation computer software. The main control computer software is responsible for the software & hardware control, setup of the simulation test and the analysis of the simulation results. The image generation computer is responsible for the generation of static and dynamic IR image, the control of moving entities in IR simulation scene and the calculation of simulation data. The two computers use network communication to transfer commands and data. The modules and implementation methods for the software are described.
We have developed a new dynamic infrared scene projector using the Texas Instruments Digital Micromirror Device (DMD) which has been modified to project images which are suitable for testing sensor and seekers operating in the UV, visible, and IR wavebands. This paper provides an overview of the design and performance of the projection system, as well as example imagery from prototype projector systems. The dynamic IR scene contains 1024×768 pixels and can be updated at a rate of approximately 85 Hz.
