摘要:
在微测辐射热计理论分析的基础上,利用数值计算的方法讨论了偏置电压与噪声、噪声等效温差(NETD)及探测率D*性能参数的关系,确定了微测辐射热计最佳偏置电压范围在1.0~4.0 V,在该范围内可以获取67.7~41.1 mK的NETD,6.1×109~1.15×1010cmHz1/2/W的探测率,品质因子达到2.6~1.4。在1.0~4.0 V的偏置电压范围内,探测器的性能可达到最优化。
Abstract:
Based on the theoret ical analysis of a microbolometer, the relationship of the bias voltage with noise, noise equivalent temperature difference ( NETD) and detectivity D* was discussed by a numerical calculation method. The best bias voltage of microbolometer ranges from 1. 0 to 4. 0 V, between which the NETD ranges from 67. 7 to 41. 1mK, the detectivity ( D* ) ranges from 6. 1 @ 109 to 1. 15 @ 1010 cmHz1/ 2/ W , and the quality factor ( Q ) ranges from 1. 5 to 1. 21. In the 110 to 410 V bias voltage ranges, the detector. s performance can be opt imized.
