Method and system for controlling the release of a resource

In one aspect, an optical sensor is used to detect defects, which can appear on smooth surfaces, is provided. The sensor includes a telecentric laser scanner and a detection unit. The scanner includes a laser for the approximately perpendicular illumination of a smooth surface, a scanning mirror, and a telecentric optical system for guiding illumination and detection beams the detection unit includes an optical detector system, a central diaphragm, which is concentrically positioned in the vicinity of the optical detector system in the direction toward the telecentric laser scanner, a highly sensitive photomultiplier for detecting scattered light, which emanates from defects on smooth surfaces, and a slit diaphragm arranged upstream of the photomultiplier.
