This is exactly what [bitluni] did in a recent video, meshing together said laser diode, UV-sensitive PLA, stepper motors and two mirrors with an Arduino-based controller to create a rather ...

Back in 2001, [Helmar] made an awesome monochrome video display out of a red laser pointer and a spinning 18-sided mirror. Blue and green lasers are much less expensive than they were a decade ago ...

In traditional DLP processing, a mercury lamp shines white light through a rotating color wheel onto the DLP mirrors. In a laser TV, three lasers shine separate red, green and blue beams onto the ...

Here I discuss the filters and dichroic mirrors used in the beam path, with an emphasis on Chroma's modified magnetron sputtering technology, MMS™: zet488/10x laser clean-up filter, zt488rdc ...

It may seem a bit strange, but bouncing lasers off mirrors installed on the Moon is something that NASA has been doing for a long time now. After all, the astronauts of the Apollo missions ...
