Color perception is based on the wavelengths of light that are reflected from, absorbed by, or emitted by an object. Light can be reflected via specular or diffuse reflection depending on whether or not a surface is smooth (like mirrors), rough, or a mixture of both. When measuring reflection from an object, it is important to consider which type of reflection is dominant, and whether some or all the reflected light needs to be collected. This article discusses the best practices for making good reflected color measurements that can be used in a wide range of optical imaging applications. Download the full article for more information.
