Dyoptyka has designed and developed a unique speckle reduction and control solution. It addresses, in a very elegant way, all the concerns raised by the use of coherent light in illumination and projection applications. It is low-cost, simple and fully integrable with a wide variety of light engine optical designs.


A high precision Moire Grating 40 LP/MM slide is used to create an image directly onto the sensor of a Qlmaging Retiga EXi camera (1392 x 1040 pixels, 12 bits, cooled CCD) placed at a distance of 20cm. Line cuts before (left) and after (right) activating the Dyoptyka Anti-Speckle Solution are shown. After activation all perceivable/subjective speckle is removed.
