摘要

光的视觉和非视觉有效性通常通过测量角膜平面上的光谱加权辐照度来确定。这通常是通过光谱辐照度或照度测量来实现的,这些测量是在带有漫射器的半球(2π)几何形状中捕获的。然而,人类的双眼视野(FOV)并不是一个完美的半球,因为它向上和向下都被遮挡。先前对FOV限制测量的研究是有限的,对于非视觉量使用半球形测量的误差是不确定的。在我们的研究中,我们通过设计和3D打印FOV遮挡作为光谱测量设备的附件来解决这个问题。我们在各种实验室(来自不同方向的光)和真实世界的照明情况(通常来自上方的光)中进行了有遮挡和无遮挡的测量。我们的研究结果显示,由于FOV遮挡,视觉和黑色素值降低。在现实场景中,这一比例从微不足道到超过60%不等。有趣的是,视觉和黑色素参数的减少是一致的,因为FOV中的光分布通常在光谱上是均匀的。一个例外发生在一个特定的人工实验室情况下,其中黑色素性日光(D65)的功效比仅由于FOV遮挡而改变了2倍以上。此外,我们观察到头部方向对所有测量量都有显著影响。总之,我们的结果强调了在实验和非视觉照明设计项目中仅依赖垂直半球测量时可能出现的重大误差。我们鼓励在典型观看方向的眼睛水平测量中(额外)使用FOV遮挡,我们正在提供开源的3D打印文件来促进这种做法。

Influence of the Human Field of View on Visual and Non-Visual Quantities in Indoor Environments.

The visual and non-visual effectiveness of light is often determined by measuring the spectrally weighed irradiance on the corneal plane. This is typically achieved using spectral irradiance or illuminance measurements, captured in a hemispheric (2π) geometry with a diffuser. However, the human binocular field of view (FOV) is not a perfect hemisphere, as it is occluded both upward and downward. Previous research on FOV-restricted measurements is limited, leaving the error from using hemispheric measurements for non-visual quantities undefined. In our study, we tackled this issue by designing and 3D printing FOV occlusions as attachments to spectral measurement devices. We took measurements with and without the occlusion in various laboratory (light from different directions) and real-world lighting situations (light typically from above). Our findings reveal a reduction of visual and melanopic values due to the FOV occlusion. These ranged from negligible to more than 60% in realistic scenarios. Interestingly, the reduction was consistent for both visual and melanopic parameters, as the distribution of light in the FOV was generally spectrally homogeneous. An exception occurred in a specific artificial laboratory situation, where the melanopic daylight (D65) efficacy ratio changed by more than a factor of 2 solely because of the FOV occlusion. Additionally, we observed that head orientation had a marked effect on all quantities measured. In conclusion, our results highlight the potential for substantial errors when solely relying on vertical, hemispheric measurements in experiments and non-visual lighting design projects. We encourage the (additional) use of FOV occlusion in eye-level measurements for typical viewing directions, and we are providing open-source 3D-print files to facilitate this practice.
