Lights are primary drivers of some crucial biological functions including vision and regulation of circadian rhythm. To understand the light exposure pattern that we experience in a daily life, many past studies measured the spectral composition of natural daylight and artificial lighting. The aim of this book chapter is to introduce a novel method to characterize directional spectral variation in natural lighting environments. An omnidirectional hyperspectral illumination map stores the spectra of lights coming from every direction toward a single point in a scene. Such illumination maps allow us to simulate a spatial light exposure pattern that reaches our eyes, providing useful resources to research areas such as chronobiology, vision science and any other fields which benefit from knowledge about the spectral nature of visual lighting environments.
灯光是一些关键生物功能的主要驱动因素，包括视觉和昼夜节律的调节。为了了解我们日常生活中的光照模式，许多过去的研究都测量了自然光和人工照明的光谱组成。本章的目的是介绍一种描述自然光环境中方向光谱变化的新方法。全向高光谱光照图存储了来自场景中某一点各个方向的光的光谱。这样的光照图使我们能够模拟到达我们眼睛的空间光照模式，为包括生物钟学、视觉科学和任何其他从视觉光照环境的光谱性质中受益的领域在内的研究领域提供有用的资源。
