曝光计

The photonic collection efficiency factor was estimated to be about 0.759 by potassium ferrioxalate actinometry.

以草酸铁钾化学光量计曝光试验对其光学性能进行了评价，光子采集效率约为0.759。

In this paper, the conversion of unit between photometry and radiometry is achieved, and the measurement of exposure in μJ/cm^2 by luminometer is realized.

文章给出了两种单位之间的换算关系，实现了用照度计测量以μJ/平方公分为计量单位的曝光量。

But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot. If you're shooting film, bracket a lot to make sure of getting the exposure you want.

把太阳放在构图中以表达沙漠中的高温和荒芜，但拍摄太阳比较麻烦，晴空下的阳光影响相机的感光计，以至于构图中其它部分曝光不足，为避免这种情况，要启用相机的手动模式，或者是将太阳从构图中排除后，半按下快门固定曝光值，然后重新选择有太阳的构图，将快门按到底。

Think about including the sun in your photograph—it's one sure way to say hot and harsh. But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot.

The beam quality of a LD pumped Nd∶YAG laser is measured with CCD camera system. The background characteristics of the CCD system and the influence of the size of integral box upon measurement results are investigated. The following conclusions can be derived form experimental results:(1) Background is strongly depend upon exposure time and pixel binning,while temperature has an ignorable effect upon it,whether with or without ambient light.(2) A 5%-cut is the minimum value in order to get a reasonable result.

采用CCD系统实验测量了LD泵浦Nd∶YAG激光器的光束质量参数，研究了CCD系统的背景噪声特性和积分区域选取对光束质量参数测量的影响，从实验数据中得到以下结论：（1）在有、无背景光两种条件下，背景记数强烈地依赖于曝光时间和像素的合并，温度影响可以忽略不计，（2）为获得M2合理的测量结果，至少要选择5%积分区域。
