Embodiment Construction
[0021] In various embodiments, the systems and methods described herein for determining the surface topography of a three-dimensional structure focus a two-dimensional array of light beams of multiple wavelengths to multiple focal lengths relative to the optical assembly. The surface topography can be determined by determining the wavelength with the best focus at each point in the two-dimensional field of view. Since each of the multiple wavelengths is focused to its unique focal length, the distance to each point can be inferred. The beam array can be used to simultaneously illuminate the structure being measured throughout the two-dimensional field of view. In various embodiments, the two-dimensional array of light beams projects the two-dimensional array of light spots onto the structure. Throughout the two-dimensional field of view, the light reflected from each spot on the structure can be directed to the two-dimensional detector, which is configured to process the refle...
