Laser Array and Key Principles for Smoke Imaging Test

Abstract:

The scene of single laser beam light is too small for the smoke field testing and the synchronization problem also unavoidable when it works at scanning way. In order to insure the measurement precision for the disturbance effect of smoke to imaging detectors, it introduces the design and key principles of lasers array with multi small power same semiconductor laser after beam homogeneous enlarge shaping. It can measure 3.5m×3.5m smoke area which can full of scene of CCD (10o×10o) at 20m distance in the field testing smoke with 3×3 beam homogenous enlarge shaping laser array.
