Abstract
For scanning active imaging systems using direct detection, it is possible to adequately model the expected speckle noise. Modifications are introduced to the theory on speckle originally proposed by Goodman to take into account the scanning effect. The model presented here is verified experimentally for a scanning active imaging system using a CO2 laser (10.6 μm). A direct relation between the reduction in the speckle noise resulting from the scanning process and the imaging resolution is demonstrated.
