Abstract

We present an overview of our on-going work in the domain of optical choppers with rotational shafts, which we proposed and patented. The different constructive solutions are presented and discussed referring to the shape of the shafts and of the slits. Our Finite Element Analyses (FEA), developed as a multi-parameter approach considering all the material, constructive and functional characteristics of the devices is briefly presented – regarding both the structural integrity and the level of deformation of fast rotational shafts with multiple holes. The potential of this novel type of optomechanical choppers is pointed out, in comparison to classical solutions of choppers with rotational disks.
