新型ARM光泽计的设计

Design of Novel Gloss Meter Based on ARM

为了解决目前光泽计在85°入射光测量结果不精确的问题,提出了一种基于ARM Cortex-M3处理器的光泽计的实现方法。该设计采用高亮度的发光二极管作为光源,通过变更入射光初始位置,实现了光泽计在85°入射光的精确测量,保证了测量精度;同时,以20°、60°和85°三种角度分别对被测物体进行照射,使其适用于不同的场合。

At present, the measurement result of gloss meter is inaccurate when the angle of incident light is 85°, thus the implementation of the gloss meter based on ARM Cortex-M3 processor is proposed. In the design, by adopting high brightness LED as the light source, through changing the initial position of the incident light, precise measurement for 85° incident light can be accomplished to ensure measurement accuracy. In addi- tion, to adapt different situation, the measured object can be illuminated respectively in three of the angles, i.e. , 20°, 60°and 85°.
