在红外敏感器中对热释电方式这一说法,外行人听来也许不习惯.它是利用铁电材料的热释电效应制成的(见图1及表1).早在1946年就知道了这种现象,而作为实用探测器是从1960年才开始的.首先实用化的是有机物TGS(三硫化甘氨酸),但是,它有客易潮解和居里点低的缺点.之后又发现了优良的单晶,现在用LiTaO_3和SBN(铌酸锶钡)制作的探测器也已经实用化.另外,最近也有用PVF_2有机薄膜制作探测器的报导. The idea of ​​pyroelectricity in infrared sensors may not be used by laymen, and it is made using the pyroelectric effect of ferroelectric materials (see Figure 1 and Table 1). As early as 1946 Knowing this phenomenon, the utility model started as early as 1960. First, the organic TGS (trisulfide) was used, but it has the disadvantage of easy deliquescence and low Curie point. Excellent single crystal, now with LiTaO_3 and SBN (barium strontium barium) detector has also been practical.In addition, there are also PVF_2 organic thin film detector recently made.
