摘要:
在微光像增强型电荷耦合器件(Intensified Charge-coupled Device,ICCD)积分时间内,空间振动影响微光ICCD相机的成像,导致成像质量下降。对于振动环境下微光ICCD相机成像,采用动态调制传递函数(modulation transfer function,MTF)评价空间振动对成像质量影响。结合微光ICCD相机特有结构,提出微光ICCD相机的动态MTF理论模型,分析低频正弦振动及高频正弦振动中,振动幅度、振动周期、积分时间等不同因素对成像质量的影响。
Abstract:
During the integration time of the low-light intensified charge-coupled device(ICCD), the spatial vibration causes a decrease in the imaging quality of the low-light ICCD camera. In the case of imaging using low-light ICCD cameras in a vibrating environment, the dynamic modulation transfer function (MTF) is used to evaluate the effect of spatial vibration on imaging quality. Combined with the unique structure of the low-light ICCD camera, the dynamic MTF theoretical model of the low-light ICCD camera is proposed, which can be used to analyze the influence of different factors such as amplitude of vibration, period of vibration and integration time on the imaging quality in low-frequency and high-frequency sinusoidal vibrations.
