Abstract:
A confocal imaging system, comprising:confocal imaging optics for imaging a focal point on an object; an illumination unit for illuminating the object using the confocal imaging optics; a photodetector for detecting the light back-scattered by the object and for optoelectrically converting the detected light; and a retroreflector, including at least two micromirrors set by 90Â° with respect to one another and which oscillate synchronously with one another, located in the optical beam path and adapted to oscillate in the direction of the optical axis in order to move the focal point in the direction of the optical axis, wherein the micromirrors are made integrally of silicon in the form of an arrangement and include mirrors and spring elements between the mirrors and a support.
