Typical Deformable Mirror
Description
Dyoptyka has developed an innovative solution, using a phase-randomizing deformable mirror, for the reduction of speckle and other unwanted interference effects that can arise when using lasers and partially coherent sources of illumination such as superluminescent diodes.It offers a unique combination of advantages over alternatives such as moving diffusers and shaking fibers with respect to: speckle reduction performance, speed, optical efficiency,electrical efficiency, size, and manufacturability.

Frequently Asked Questions
The phase-randomizing deformable mirror is designed to reduce speckle and unwanted interference effects that can occur when using lasers and partially coherent sources of illumination.
The deformable mirror achieves speckle reduction through phase randomization, which generates sequences of uncorrelated effects over the integration period of the sensor, resulting in averaging and reduction of speckle.
The deformable mirror offers advantages such as optical efficiency, speed, size, and reliability compared to moving diffusers.
The potential applications of the deformable mirror are discussed in the research article and include areas such as lasers and laser optics, speckle reduction, displays, holographic display, interferometry, and microscopy.
Speckle contrast ratio can be reduced through spatio-temporal averaging by generating multiple speckle patterns of equal mean intensity during the integration period, resulting in a lower speckle contrast ratio.
