入射到人类视网膜的光辐射刺激视觉，并为大脑的生物钟提供一天中的时间信息。视觉系统和昼夜节律系统对光辐射的反应截然不同。开发和测试了一种名为日光计的设备，以帮助实现昼夜剂量测量系统。日光计是一种轻型的头戴式设备，可以记录视觉和昼夜节律系统的辐射暴露估计，并且是专门为野外使用而设计的。除了记录光谱加权辐射测量，它还记录头部位置和运动，作为人类昼夜活动的代表。本文提供了视觉系统和昼夜节律系统的辐射差异的背景，并描述了该原型装置的开发和测试。
Optical radiation incident on the human retina stimulates vision as well as provides time-of-day information to the brain's circadian clock. The visual and circadian systems respond very differently to optical radiation. A device, the Daysimeter, was developed and tested to help progress towards a system of circadian dosimetry. The Daysimeter is a lightweight, head-mounted device that records radiation exposure estimates for both the visual and circadian systems, and is specifically designed for field use. In addition to logging spectrally weighted radiation measurements, it records head position and motion to be utilized as a representation of human circadian activity. This paper provides background on the differences between radiation for the visual and circadian systems, as well as a description of the development and testing of this prototype device.
