The design of a complex weather environment simulation system for evaluating imaging detection efficiency

Abstract

Common electronic imaging can be easily affected by some weather factors. In order to explore the influence of several main weather factors in Lab circumstance, it is necessary to develop a weather simulation system for evaluating imaging detection efficiency. In this paper, a design and manufacture of a relatively complex weather environment simulation system for evaluating imaging detection operation is introduced. The proposed system can be used to simulate several common weather conditions such as rain, fog, air flow, and temperature variance, in a small spatial size of 60×45×45cm, which covers a large spectral range from the visible to infrared wavelength bands of 0.38μm~14μm and can be utilized to conveniently explore the adverse effects of the weather factors mentioned above on imaging detection. Firstly, the feasibility for simulating different factors including rain, fog, air flow, and temperature variance, is demonstrated. The overall system is designed and realized based on the corresponding electrical and optical and mechanical parameters. The velocity distribution of air flow is simulated by Fluent. The components of the system are made and assembled by traditional processing methods such as Computer Numerical Control. Finally, the overall system is tested, and the results show that the design goals have been attained well. The system can be applied to simulate imaging detection experiments.
