Zusammenfassung:Methods for detecting a working area of a generative manufacturing device and manufacturing devices for generatively manufacturing components from a powder material are disclosed. The methods include scanning of an optical working beam of the generative manufacturing device in the working area, detecting signal values of remitted light of the optical working beam traveling along an optical axis of the optical working beam in a location-dependent manner, wherein a signal value is assigned to each location of the scan of the optical working beam in the working area, and obtaining an image of the working area from the location-dependent detected signal values. The optical working beam for detecting the working area is operated with an optical output power that is reduced compared to a lower power limit for the optical output power of the optical working beam used during generative manufacturing.
