would this glass meets the requirement what i need ?? Also...
i need this kind of laser for my 3d face recognition system.this laser is pointed front of the face with multiple laser lines.these laser lines are horizontal and parallel.so i need to generate multiple lines in one laser.
can you tell me how to generate multiple lines using a one laser??
I need to know ,is there any uniform laser line modules which they have multiple lines.i need a laser that should have generated more than one line.about 25 lines(all are vertical and parallel) is very good.are there anyone who can tell me how to build that meets above requirement.please can...
