中文摘要:红外探测器应用时受环境影响或外力作用会产生机械振动,从而引起振动噪声。噪声电压干扰会极大地降低探测器的跟踪能力和探测距离。因此振动噪声引起广泛关注,它是评价探测器的重要参数,也是剔除不合格探测器的重要手段。随着国内与国际市场对红外探测器的需求日益增加,传统人工监测并记录的测试方法已不能满足目前的产能需求。研究了一款支持不同规格红外探测器的振动噪声自动采集系统,主要介绍了系统设计原理、系统组成、各模块功能等。该系统的成功应用有效解决了红外探测器振动噪声测试效率低、准确率低的问题。以一款多元探测器为例,测试效率提高3倍,准确率为100%。该系统实现了振动噪声测试自动采集、无人值守,节约了人力成本。

Design of Automatic Acquisition System for Vibration Noise of Infrared Detectors
Abstract:During the application of infrared detectors, mechanical vibrations may occur due to environmental influences or external forces, resulting in vibration noise. Noise voltage interference can greatly reduce the tracking ability and detection distance of the detector. Therefore, vibration noise has attracted widespread attention, as it is an important parameter for evaluating detectors and an important means of removing unqualified detectors. With the increasing demand for infrared detectors in both domestic and international markets, traditional manual monitoring and recording testing methods can no longer meet the current production capacity requirements. A research is conducted on an automatic acquisition system that supports the vibration and noise of infrared detectors of different specifications. The system design principle, system composition, and functions of each module are mainly introduced. The successful application of this system effectively solves the problems of low efficiency and accuracy in vibration noise testing of infrared detectors. Taking a multi detector as an example, the testing efficiency has increased by three times and the accuracy is 100%. The system realizes automatic collection of vibration and noise testing, unmanned, and saves labor costs.
