How does the optical system of a structured light 3D scanner work?

AI Thread Summary
The optical system of a structured light 3D scanner projects a series of light patterns onto the object being scanned. By analyzing the deformation of these patterns as they hit the object's surface, the scanner can determine the Z coordinate, which represents depth. This process involves capturing images with a camera and using triangulation to calculate the 3D coordinates of points on the object's surface. Additional resources are available for a deeper understanding of the scanning process. Structured light 3D scanners effectively translate 2D patterns into accurate 3D models.

Hello, can anyone explain me how optical system of a structured light 3d scanner like this one works? I tried to google it, but still didn't understand how it get's Z coordinate.

Welcome to the PF. :smile:

That same website has more information on how to do the 3-D scans...

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
