提出并论证了一种新型的场发射型红外光传感器。证实了热释电材料在红外光照射下的电子发射现象。在阶跃红外光照射下，电子发射电流迅速增加，衰减缓慢，峰值发射电流与入射红外光功率成正比。排放效率为35%。利用该电子发射器件作为光电阴极，搭建了图像传感器样机，并成功地拍摄了红外图像。
A novel field emission type infrared light sensor was proposed and demonstrated. The electron emission phenomena from pyroelectric material by infrared light irradiation were confirmed. The electron emission current increased rapidly and decayed slowly when a step infrared light was irradiated, and the peak emission currents were proportional to the incident infrared light power. The emission efficiency was 35%. We constructed a prototype image sensor by using the electron emission device as a photocathode, and infrared light image was successively taken.
