摘要：
The use of optical techniques for the measurement and characterization of physical phenomena is of great interest in the scientific and industrial communities. This work shows the implementation of an integrated system for measuring Multi-angle Laser Light Scattering on a Field Programmable Gate Array. The embedded design delivers a compact and highly competitive system. The system is able to display, in real-time, the light intensity from a photo-detector array showing in this way the corresponding pattern distribution of the scattered light at 16 sensing points. Some laser light scattering patterns from metallic samples with different roughness are shown.
