摘要:
根据国内常见的微测辐射热计器件结构原理及读出电路,研究了偏置电压与噪声等效温差的关系,推导了偏置电压与探测器输出电压的线性方程。提出了基于直方图统计的偏置电压调整模型,降低探测器的噪声等效温差,增强图像对比度,使此种类型的红外探测器能够用于各种目标场景的探测。实验证明,偏置电压自适应调整技术应用于红外图像实时处理系统中,得到了很好的处理结果。
Abstract:
Relations between the bias voltage and the detector noise equivalent temperature difference (NETD), the linear equation of bias voltage and detector output were presented on the basis of microbolometer structure and readout integrated circuit (ROIC). A model of redress bias voltage was proposed based on histogram statistic to improve the detector NETD and image contrast, consequently, the infrared detector achieves a good effect for different scene. The experiment results indicate that the method is effective on the real-time infrared image platform.
