Abstract
This article presents a compact visual colorimeter for the purpose of measuring color-matching functions (CMFs) of individual observers through psychophysical experiments. Constructed from 3D-printed parts, optical elements, and LED-based light engines, the colorimeter facilitates the juxtaposition of two fields to create a bipartite field. The system underwent characterization to evaluate factors that may impact color-matching experiments, such as LED-light stability, spatial homogeneity of the bipartite field, and potential stray-light leakage. The study aimed to assess the accuracy and performance of the system in measuring individual observer CMFs. Results indicate that the system is stable enough to measure both intra- and inter-observer variations in CMFs.
本文介绍了一种紧凑型视觉测色计，用于通过心理物理实验测量个体观察者的色彩匹配功能（CMF）。该测色计由三维打印部件、光学元件和基于 LED 的光引擎构成，可将两个场并置以创建一个双方场。对该系统进行了表征，以评估可能影响配色实验的因素，如 LED 光的稳定性、双方场的空间均匀性和潜在的杂散光泄漏。研究旨在评估系统在测量单个观察者 CMF 时的准确性和性能。结果表明，该系统足够稳定，可以测量观察者内部和观察者之间的 CMF 变化。
