Laser Speckle Detection System for Seed Viability Assessment

Article Preview

Abstract:

This work presents a new detection system for seed viability assessment. The theoretical of the system is based on laser speckle or dynamic speckle, an optical phenomenon produced by interference of light. In the present work, the detection of a single in a period of time is been concentrate. The various parts and working principle of the laser speckle detection system explain detailed and the feasibility of this system is experiment in this paper. The result shows that this system is available in this field, and it can support the further study.
