High all , i am electrical engineer & fpga expert & new to laser scanners .
i am trying to build amateur laser projector with X-Y Scanning .
i prepared hexapod mirrors and attached them to the motors and built XY Scanning unit . but my 10mw red laser doesnt enough power for scanning . so i must use higher power than this .
the solution came from modulation frequency in need . i read some major topics in this section and received good informations about laser beam modulation. hower something still need to be answerd .
is the normal 100mw laser diodes are capble to be switched on & off with frequency about 1Mhz ?!
with resolution of 320x24 and 20fps i need a 1.5Mhz beam modulation . so is the laser diode right choise for this or not ?
i searched for 22x DVD-RW laser diod and i know its about 200 mw power with modulation frequency about 231Mhz so is it right for me ?!
Thanks
Clurado.
