Keywords: optical coherence In laser projection systems the observer in the far field of the image points on the screen will recognize serious speckle noise. There are many methods to The basis of this approach is a thin, elastic membrane that carries a lightweight diffuser in its center and four electrodes surrounding it.

for speckle reduction. To date, the speckle reduction by piezo-electric benders have not been reported, although the cylindri-cal piezoelectric transducers have been utilized to provide ra-dial extension of coiled multimode fibers for speckle reduction [12,13]. In this work, the incoming laser beam is steered by the two piezoelectric benders. The reduction of speckle is important for applications where a homogeneous laser output of uniform intensity is ideal, such as laser-scanning microscopy, flow cytometry, and DNA sequencing. By using the De-Speckler to average the modal noise and greatly reduce speckle…
