There are red lasers; there are green lasers - and they all speckle. Laser speckle is the In a laser projection display, the presence of speckle tends to mask the image information and therefore its reduction is highly desirable. Speckle contrast reduction 22 Apr 2019 We need, however, different fabrication protocols and technologies for reducing the laser threshold and controlling its emission. Here, we 12 Oct 2018 Using optical chaos from semiconductor laser with feedback to reduce speckle in double pass images. Goal of project. Source. .

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.

2020-01-01 · We proposed a speckle reduction system in the laser pico-projector. The holographic diffusers and the fast electrically tunable lens (FET lens) were adopted in the method of the speckle reduction. This research focuses on speckle reduction by the different divergence angle of the holographic diffusers.

Speckle is the main obstacle for the use of laser light sources in projection technology. This paper focuses on speckle suppression by the reduction of temporal coherence which is provided by the broadband laser light. The investigation of the effect of laser spectrum width and multiple lasers on sp … Through theoretical analysis the reasons of generating laser speckle, we use an optical scheme for reducing composite speckle in the three LCOS laser projection system. The project of rotating diffuser has a simple optical structure and can be easily implemented. We propose a design for speckle reduction in a laser pico-projector adopting diffusers and deformable mirrors.

We propose a design for speckle reduction in a laser pico-projector adopting diffusers and deformable mirrors. This research focuses on speckle noise suppression by changing the angle of divergence of the diffuser. Moreover, the speckle contrast value can be further reduced by the addition of a deformable mirror.

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, maximized performance can be achieved.
