SCA640-120GM 替换传感器

每个摄像机测试时的照度都是固定的。用Basler A602fc相机测量了长时间内和换灯后的照度漂移。参考相机提供了一个强度因子，用于计算每个相机测量的辐照度。

辐照度使用国际照明公司的IL1700辐射计测量(检测器:SEL033 #6285;输入光:w# 9461;滤镜:f# 21487;定期校准)。
辐射计的精度规定为±3.5%。
测量的辐照度绘制在图1中。

总量子效率随波长的变化曲线如图3所示，是根据4.1.1节所示的单次测量总量子效率计算得到的。对于曲线的形状，使用传感器数据表中的数据。

对于波长λ为[nm]的单色光，在[p ~]的曝光时间内，信噪比SNRy(µp)与在一个像素中收集的光子数µp绘制。波长应接近量子效率的最大值

SCA640-120GM

The illumination during the testing on each camera was fixed. The drift in the illumination over a long period of time and after the lamp is changed is measured by a reference Basler A602fc camera. The reference camera provides an intensity factor that was used to calculate the irradiance for each camera measurement.

The irradiance was measured using an IL1700 Radiometer from International Light Inc. (Detector: SEL033 #6285; Input optic: W #9461; Filter: F #21487; regular calibration).
The accuracy of the Radiometer is specified as ±3.5%.
The measured irradiance is plotted in figure 1.

The curve of the total quantum efficiency versus the wavelength as shown in figure 3 was calculated from the single measured total quantum efficiency as presented in section 4.1.1. For the shape of the curve, the data from the sensor data sheet was used.

Signal-to-noise ratio SNRy(µp) is plotted versus number of photons µp collected in a pixel during exposure time in [p∼] for monochrome light with the wavelength λ given in [ nm]. The wavelength should be near the maximum of the quantum efficiency
