OCT has features of non-contact, fastimaging (real-time dynamic imaging), high detection sensitivity and so on. Han’sScanner provides high-speed precision galvanometer control system andsolutions. The solutions combined with optical system, based on the principleof weak coherence interference, detects the back-reflection or scatteredsignals of incident weak coherent light at different depths of biologicaltissue, through scanning it can reconstruct the 2D or 3D images of the internalstructure of biological tissue or material.
