室温下工作的热释电混成热象传感器的研制工作最近已取得了明显进展。采用热释电列阵与硅CCD等混成全固体热象传感器已达到实用的性能。这种传感器不需要致冷,坚固且价格较低,必将获得广泛的应用。因为对于一般应用而言,多元列阵的探测率D~*为1×10~8cm·Hz~1/2/W,做成传感器后,噪声等效温差(NETD)为0.2℃时,就能满足要求。就材料而言,最先采用的是铌 The work done at room temperature pyroelectric hybrid thermal imaging sensor has made significant progress recently. The use of pyroelectric arrays and silicon CCD hybrid solid thermal imaging sensor has reached practical performance. This sensor does not require refrigeration, solid and low price, will get a wide range of applications. Because for general applications, the detection rate of D * * is 1 × 10 ~ 8cm · Hz ~ 1/2 / W for multi-array array. When the noise equivalent temperature difference (NETD) is 0.2 ℃ fulfil requirements. In terms of materials, niobium is the first to be used
