Claim Text:
1. Apparatus for detecting a 3D structure of an object, comprising: a first laser emitter which generates laser radiation having a first wavelength and a second laser emitter which generates laser radiation having a second wavelength different than the first wavelength, wherein the first and second lasers are positioned such that the illuminating radiation of the first laser emitter and the illuminating radiation of the second laser emitter impinge upon the object at different angles of incidence; optical devices, including a beam splitter which splits the laser radiation from each of the first and second laser emitters into reference radiation and illuminating radiation, wherein the illuminating radiation impinges upon the object to be measured, is reflected by the object as object radiation, and interferes with the reference radiation to form interference patterns; a detector which records the interference patterns; and a measuring device which measures the two wavelengths of the laser radiation of the laser emitters and influences the recording of the interference patterns.
