MOUNTING POSITION MEASURING DEVICE

摘要

In a work to match a reflecting mirror (or a facet (31)) to be mounted on a heliostat (3), artificially to a toroid (53), an adjusting method and a mounting position measuring device are provided for measuring the mounting position of the facet (31) precisely so as to perform the mounting adjustment efficiently and simply. In a method for mounting the reflecting mirror (or the facet (31)) constituting the heliostat (3) for condensing the solar ray, the facet (31) is disposed so that its laser-reflected light (52) may reach a virtual passing point (52b) of a laser point measuring unit (12).
