Goniometric Measurements Using Photometric Robots With Imaging Luminance Measurement Devices (ILMDs)

When measuring display‐specific parameters such as luminance, contrast, or color, which depend on the viewing angle, precise and reproducible positioning of the measuring system is essential for achieving reliable results. This study examines how photometric robots, which integrate imaging luminance measurement devices (ILMDs) with industrial robotic systems, can be used as goniophotometers for display and illuminated object measurement technology. Physical limitations are discussed, and the position accuracy and repeatability are analyzed. Recent advancements in this field are explored, including enhanced goniophotometric functions, spectroradiometer integration, absolute robot calibration methods, and specialized software innovations.
