Calibration And Verification

The dazzling process of the laser has been digitally simulated. First, the optical design software (ZEMAX) is combined with the scientific programming language (MATLAB), then the ray tracing is used to build the scattering model of each optical element, and finally compared with a simpler model based on CIE disability glare data to achieve the calibration and verification of the software simulation effect. The results show that this advanced optical eye simulation technology can be used to study the laser glare efficiency, and it is possible to expand the scope of application of the analysis model.

Illuminance Uniformity

This study presents the optical design of light guide prisms for automotive tail light applications to obtain the optimum luminous intensity and the illuminance uniformity. The design was achieved using optical design software, SPEOS. By considering the axial luminous intensity and legal requirements, the optimum prism angles of light guides were determined by simulations. After determining the prism angles, the effect of different surface roughness on the luminous intensity and the illuminance uniformity was investigated. The light guides designed by considering data from the simulation were manufactured as prototypes and their photometrical measurements were made. These measurements were compared to the simulation results. It was observed that simulation and prototype results are well in agreement with each other. Furthermore, it was found that as the surface roughness increases both the luminous intensity decreases and the illumination becomes more uniform.
