Jul 6, 2010 · A grid could work, but you'd need a whole lot of lasers and detectors. Getting all of them set up, especially at millimeter spacing, would pretty difficult and require a lot of wiring. You'd probably be better off just using the webcam and some image processing methods to detect where the object is.

Dec 19, 2017 · Im struggeling with finding a lens that will project a square laser grid of around 10x10 to 20x20 square lines (not dots!) in the "hobby" side of the price range. I have found some suppliers that are more aimed at the professional machine vision market, and the lenses cost a couple of hundreds of dollars ++. I have found one cheap model:

Aug 17, 2019 · No one has mentioned that using a mirror to project the beams from a diffraction grating downward would not give you parallel beams. They will continue to diverge like they do without the mirror. If you want parallel beams you will have to project then onto a surface, or use the other more...

Jul 28, 2009 · hi, well for the measuring part i found a solution with a laser level i found, for the grid i was looking, as pwnstar said , with some optics.. i think with some mirrors ect i would be able to correctly project the dots i need, for the measure i realy use softwares that can track the camera movement and can give the information i need what i realy need for that sofware are …

Apr 2, 2010 · Hi. I am looking for a portable laser that can project a laser grid on floor or wall of size 5x5 meters. The laser must be portable and preferable small. It must be able to run on batteries for several hours. Can anyone direct me to some commercial products that fit this description. Then...

Sep 4, 2008 · You can use any cross generating laser and a diffraction grating to create a very large grid with many rows. Ex. A Brightline cross gen from Lasaerglow and a megamatrix diffraction grating from novalasers will get you a solid grid pattern with dozens of rows and columns made of clear, focusable lines.

Jul 17, 2009 · This grid is large enough so that you can hook your computer up to a large HDTV to check your whole field of view if you're concerned. To use the grid, cover one eye and look at the central dot on the grid. Below, a normal Amsler grid is on the left. If you have some sort of eye damage, you might see spots on the grid like this, on the right:

Nov 24, 2007 · I think it would be really cool to make a laser grid, but I'm not sure how to start. Attached is what I'm looking to make.. It would be cool to get a fine grid and take pictures with the laser pointed to 3d objects! Can this be done without a scanner? Perhaps with one of those crappy caps that comes in weird shapes on 5mw res pointers?

Jan 24, 2016 · You can use any cross generating laser and a diffraction grating to create a very large grid with many rows. Ex. A Brightline cross gen from Lasaerglow and a megamatrix diffraction grating from novalasers will get you a solid grid pattern with dozens of rows and columns made of clear, focusable lines.

May 2, 2016 · First off, I'm super new to lasers in general, so thank you to anybody who takes the time to read through this short post. I'm looking to buy/design/order/make/get my hands on a diffraction lens for a green laser that would emit an 8x8 grid with no repetitions. I …
