A huge progress in the laser technology, in particular the creation of the semiconductor laser, allows to see the method of laser plumbing as a method of the future which can replace mechanical plumbing. Therefore, the issues connected with the method of plumbing become more and more popular. The most important ones are: - directing the laser beam, - determining the center of the laser beam at the point of target (detection of the laser beam). The issue of the focus of the laser beam, thanks to the researches made in 1970 and 1980 and aimed to the use of the laser light in the measurements of the shafts, is practically resolved (Jóźwik 1994). The construction of many types of laser plummets (based on different operating principles), as well as the possibility of adapting the optical plummets to cooperate with the laser diode, enables to focus the laser beam with high precision. The second issue concerning the detection of the laser bean, limited so far the possibilities of applicability of this method. Currently, the most common method of detection is a visual method (used by PMG Katowice, ZG Rudna, ZG Polkowice) aimed to specify the center of the laser beam on the observation wheel with an accuracy of 3mm. There is also applied the photogrammetric method based on the digital photography used by DARTECH company from Ruda Śląska. These methods are either not very accurate (the visual method) or allowing to perform measurements only at selected levels of measurement (the photogrammetric method).
