Compact laser scanner with 72 degree by 92 degree scan angle

www.ScannerMAX.com Saturn 1 galvanometer scanner with custom mirror set for projecting beams up to 2mm through a scan angle of 72 degrees on one axis by 92 degrees on the orthogonal axis. Mirrors are silver allowing for the projection of IR through visible wavelengths. The servo driver is our Mach-DSP digital galvo driver.

I have a question. How fast the galvo has to be to scan 240 parallel horizontal lines with maximum angle at 60fps? Is there any formula that would allow me to calculate that?

[@ScannerMAX]

240 lines could be 240 "scans". If you use bidirectional scanning using a triangle wave, then you can think about it as 120 "cycles" of the triangle-wave. 120 cycles that takes place 60 times per second would be 7200Hz. Certainly no galvo scanner can do that at 60 degrees. A polygon scanner would conceivably be able to do that, and the scanning waveform would be a sawtooth-wave instead of a triangle-wave.

Is this being used for some type of structured light scanning?

No the particular customer was using this for wide angle graphics projection (what is referred to as "Optical Layout Template" in our industry)
