色觉代表了感知的一个重要方面,它最终使各种各样的物种在自然界中茁壮成长。然而,在实验室环境中构建彩色视觉刺激的统一方法是缺乏的。在这里,我们提出了刺激设计方法和附带的程序包,以有效地探测任何已知光感受器光谱灵敏度的物种的色彩空间。我们的硬件不可知的方法结合了光感受器模型的框架内的原则的统一。这使实验人员能够确定最有效的方法来组合多个光源来创建所需的光分布,从而轻松地构建相关的刺激来绘制生物体的色彩空间。我们包括方法来处理光感受器光谱灵敏度的不确定性,以及最佳地重建高光谱图像鉴于最近的硬件进展。我们的方法支持色彩视觉科学的广泛应用,并为跨实验系统的统一刺激设计提供了框架。这篇文章是主题问题“理解色觉:节肢动物的分子、生理、神经和行为研究”的一部分。
Colour vision represents a vital aspect of perception that ultimately enables a wide variety of species to thrive in the natural world. However, unified methods for constructing chromatic visual stimuli in a laboratory setting are lacking. Here, we present stimulus design methods and an accompanying programming package to efficiently probe the colour space of any species in which the photoreceptor spectral sensitivities are known. Our hardware-agnostic approach incorporates photoreceptor models within the framework of the principle of univariance. This enables experimenters to identify the most effective way to combine multiple light sources to create desired distributions of light, and thus easily construct relevant stimuli for mapping the colour space of an organism. We include methodology to handle uncertainty of photoreceptor spectral sensitivity as well as to optimally reconstruct hyperspectral images given recent hardware advances. Our methods support broad applications in colour vision science and provide a framework for uniform stimulus designs across experimental systems. This article is part of the theme issue ‘Understanding colour vision: molecular, physiological, neuronal and behavioural studies in arthropods’.
