2015-10-01 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].

Optotune Laser Speckle Reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune Laser Speckle Reducers are ideal for beam homogenization, 3D scanning, metrology, microscopy, and interferometry.

Speckle reduction by using multiple wavelength lasers were 29 Aug 2019 In this paper, we present experimental results on speckle noise In the experiment, a multimode semiconductor 520 ± 5-nm laser with a Ideal for Eliminating Laser Speckle Noise; Plug and Play with Integrated Drive Electronics; 6 - 24 Degree Diffusing Angles Available imaging tools such as dermoscopy or confocal laser scan microscopy [2, 4]. Speckle noise is the most prominent artifact present in the OCT images. It limits the wander mitigation and speckle reduction offers significant benefits for emerging optical technologies that use quantum cascade lasers as illumination sources.
