Optical design of luminous intensity measuring systems based on imaging sphere

A new LED measurement method of light intensity spatial distribution was proposed. The measurement system of the method and the key components of the optical system were designed. The surface type of the freeform reflector was designed with Matlab and simulated with Solidworks. The double gauss objective was designed and optimized by using Zemax. The optical system was simulated with the optical ray tracing software LightTools to verify its feasibility. The key performance indicators such as the minimum angular resolution and the dynamic range of the system were analyzed. The results show that it is feasible to measure light intensity spatial distribution with the system based on imaging sphere.
