Photometry Systems Calibration Correction factors applied to luminous flux can include: 修正因数适用于光通量包括： Intensity Distribution Response Correction: The response of the sphere is not spatially uniform due to different angular luminous-intensity distributions from those of the test lamp as compared to the calibration lamp. 强度分布反应修正：球体反应空间不一致取决于从标准灯不同角度发光亮度分布 -Positional Correction: Ideally, all measured test lamps should be measured in the same positional orientation as the standard lamps during calibration procedures. In some cases, lamps must be measured in a different orientation. This correction is also important when making measurements on position limited lamps. In order to account for any effects that may occur due to a combination of non-uniform spatial issue with the sphere, a positional correction factor is used. -位置修正：理想上所有测试的试验灯应该安装在相同的位置方向按照标准灯的标准程序。有时候，灯必须在不同的方向上测试。这个修正同样重要当靠有限灯管来确定测量位置。为了解决任一效果的可能发生，取决于球的空间不一致问题，所以使用了位置修正因数。 * 第27页，共40页，编辑于2022年，星期五 Photometry Systems Calibration Calibration 1: Detector Based Calibration – Luminous Flux Calibration 标准1：探头标准-光通量标准 (1) Define the “null” condition of the sphere Example: Empty socket, no lamp. 定义球体“无效”条件 如：没有灯 (2) Determine SAF of the calibration lamp standards 确定SAF标准灯的标准 (3) Determine the Attenuator Setting确定衰减器设置 Measure standards – raw data, no correction factors 测量标准-原始数据，没有修正因数 Attenuator setting is set to force the following: 衰减器设置是强制设置如下： Certificate Lumens = SAF*Raw Lumens 证明光通量=SAF*原始光通量 Note: Raw Lumens = Attenuator Setting*Detector Signal. 注意：原始光通量=衰减器设置*探头信号 Therefore: Lumens = SAF* Attenuator Setting*Detector signal. 因此：光通量=SAF*衰减器设置*探头信号 Since we have the SAF, we can set the attenuator setting. 一旦我们有了SAF，我们就可以设置衰减器设置了。 Measure standards as a test测试时测量标准 Measured lumens = SAF*Raw lumens. 标准的光通量=SAF*原始光通量 Confirm the data matches the certificate assigned value. 确认证明赋值的数据匹配 * 第28页，共40页，编辑于2022年，星期五 Photometry Training August 2006 积分球校准操作说明 第1页，共40页，编辑于2022年，星期五 Photometry光度测量 What is photo
