摘　　要：在全面分析光电成像传感器噪声源的基础上,提出了采用光子响应非均匀性因子Φ来评价光子响应非均匀性噪声,确立了Φ的测试方法,搭建了具有双积分球结构的测试平台完成了测试,并通过比对实验分析了光子散粒噪声、暗噪声和电路读出噪声对测试结果的影响,最后详细分析了整个输出范围内,光子响应非均匀性噪声与入射辐照度的关系,为光电成像传感器其他指标的测试和光子响应非均匀性噪声校正提供了有力的支持。It is proposed that the photon response non-uniformity （PRNU） factor φ can be used to evaluate photo response non-uniformity noise, which is based on comprehensive analysis of all kinds of optical imaging sensor noise. A test method has been established, and a test platform has also been built with a doubleintegrating sphere structure. Finally, the relationship between the PRNU noise and the incident irradiance is discussed in the whole range of the output values, which has provided a powerful support for the test of other indicators and the correction of photon response non-uniformity.
