LTPRSM series units can be interfaced with any type of optics, but the best results are achieved with bi-telecentric lenses.
The projection area is undistorted since tilting the pattern causes a linear extension along only one direction.
Excellent results can also be obtained with zero distortion macro lenses; here, the magnification changes along both axes, but image resolution and distortion still easily allows 3D reconstruction.
With non bi-telecentric lenses, a square pattern becomes a trapezoid in the projection plane, whose parallel sides are indicated as “w” and “W” in the drawings below.
The projection area shown in the chart are also a good approximation for standard C-mount lenses used as macro lenses (eventually equipped with spacers).
