光电系统特性的准确建模是判定一个系统设计水平的关键。近年来凝视焦平面阵列在3~5μm和8~12μm波段上均可获得.由于其体积小且不需移动其它部分,故二维阵列对扫描的前视红外(FLIR)特征模型必要的改进.凝视焦平面阵列和扫描阵列之间有几点不同需要探讨,扫描阵列在一个方向(垂直)上采样,在另一个方向(水平)上扫描,这跟通常的输出器件(原理上)相似.因此水平和垂直方向上是独立操作的.二维焦平面阵列在两个方向上采样,而且对探测器时域噪声的处理也不同,在扫描阵列中以空间噪声的形式出现,而在绝大部分凝视阵列中被求积分.有人记录过.凝视焦平面阵列模型所具有的主要方面,其中包括两种典型的探测器:硅化铂(PtSi)肖特基势垒二极管探测器和碲镉汞(HgCdTe)探测器.目前已有方程可将这两种探测器综合起来,其中包括噪声和响应,并有能力引入新型探测器.焦平面阵列模型已用FORTRAN语言编程,输入包括光学技术要求、温度、稳定性和探测器参数,输出包用噪声等效温差(NETD)、最小可分辨温差(MRT)和最小可探测温差(MDT).这种模型运算快并可在低成本计算机上进行行业研究.
Accurate modeling of photovoltaic system characteristics is the key to determining the level of a system design. In recent years, the focal plane array can be obtained in 3 ~ 5μm and 8 ~ 12μm bands. Because of its small size and without the need to move other parts, the two-dimensional array provides the necessary improvements to the scanned forward-looking infrared (FLIR) feature model. There are a few differences between looking at the focal plane array and the scanning array. The scanning array is sampled in one direction (vertical) and scanned in the other direction (horizontal), which is similar (in principle) to the usual output device. Therefore, it operates independently in the horizontal and vertical directions. Two-dimensional focal plane arrays are sampled in both directions, and the detector’s temporal noise is also handled differently, in the form of spatial noise in the scanning array, and in the vast majority of gaze arrays. Someone recorded. Gazing at the main aspects of a focal plane array model, there are two typical detectors: platinum silicide (PtSi) Schottky barrier diode detectors and mercury cadmium telluride (HgCdTe) detector. There are equations available to combine these two detectors, including noise and response, and the ability to introduce new detectors. The Focal Plane Array model has been programmed in FORTRAN with inputs including optical specifications, temperature, stability and detector parameters, output package noise NETD, MRT and MDT ). This model is computationally fast and enables industry research on low-cost computers.
