摘要
阐述热电堆红外探测器的赛贝尔克效应原理,它的特点是室温工作非制冷,光谱响应范围宽,输出电路简单,成本低,它是红外领域研究热点之一.热电堆在等效电路上有一个电阻,其热噪声是热电堆红外探测器的关键指标,除了热电堆,读取电路本身也有噪声.探讨高端热电堆芯片读出电路降噪结构,系统分析其降噪分析方法和机理,从而在热电堆传感器设计阶段能够分析出系统性能.
Abstract
This paper expounds the infrared detectors and principle of Seibelk effect.It is characterized by uncooled operation at the room temperature,widely spectrum response range,circuit output simply and low cost.Thermopile is equivalent to a thermistor on the circuit,the thermal noise is the key indicator,and its performance is also related to the circuit.This paper proposes a new approach to a system noise analysis,which can analyze the system performance on the sensor design stage.
