I don’t know how the scanning of this projector will affect the fact that a high resolution is obtained by shifting the matrix (the matrix size is 0.33 inches there)
“Correct” FullHD starts with 0.46 inch matrices
Good to know OBN, can you please show where you can find all these informations about matrices?OBNRacerMan wrote: ↑11 Jan 2020, 09:51I don’t know how the scanning of this projector will affect the fact that a high resolution is obtained by shifting the matrix (the matrix size is 0.33 inches there)

When I was picking up a projector for a 3D scanner, I read a lot of information on "projector" forums, where I found out that cheap FullHD DLPs have high-frequency matrix shift technology (120Hz) in order to be able to display the general projection field, which consists of two pieces .
Luckily here in NYC (and Amazon in the US) that have very liberal return policies. I can buy a projector and try it for 30 days and return it no questions asked. I was able to try out a couple of small laser projectors (which gave bad results) that way. If madding likes the PF50 I will get one to try. Finding a spec sheet that includes the pixel orientation screen seems to be harder to do.OBNRacerMan wrote: ↑11 Jan 2020, 13:38When I was picking up a projector for a 3D scanner, I read a lot of information on "projector" forums, where I found out that cheap FullHD DLPs have high-frequency matrix shift technology (120Hz) in order to be able to display the general projection field, which consists of two pieces .
Since everywhere they write about projectors from the point of view of watching a movie, no one could say the suitability (or unsuitability) of this technology for 3D scanning (and buying something like that to test is too expensive for me)
Yes, I am also very interested in how such a projector as a part of a 3D scanner will show itself. I found this on AliExpress (but buying from this year is already much more difficult - they imposed a limit of 200 euros on purchases in foreign online stores).
