CDA µFunctional Solutions - diffractive optical elements

DOE Linsen Optische Encoder

DOT GENERATORS

The dot and line generators are forms of diffractive optical elements splitting a light beam into a dot or a line pattern. This kind of optical elements is often used for 3D-sensing. This kind of use is also called "structured light" (SL).

DOT GENERATORS

The dot and line generators are forms of diffractive optical elements splitting a light beam into a dot or a line pattern. This kind of optical elements is often used for 3D-sensing. This kind of use is also called "structured light" (SL).   

The projection of such patterns into the space makes it possible to capture shapes and movements within the projection in all three spatial dimensions by a camera system. Typical applications are, for example, face recognition, motion control, iris control or the simultaneous recognition of own movement in space (Simultaneous Localization and Mapping = SLAM)
