Enhancing laser speckle reduction by decreasing the pitch of a chiral nematic liquid crystal diffuser

The artefact known as speckle can plague numerous imaging applications where the narrow linewidth of laser light is required, which includes laser projection and medical imaging. Here, we report on the use of thin-film chiral nematic liquid crystal (LC) devices that can be used to mitigate the influ...
