I am sure this optical setup will be perfect.

I will use ldrs as sensor receiver.When object placed between sensor and lens,it will have a dark projection of object on ldr array.
Will a red line laser and collimater lens...
I built a ldr array(approx.30 ldrs)All of them adjacent.I want to focus laser beams on them.So I have to put laser diode in front of each ldr.And important part is each ldr must have its beam from the front one.But glueing is problem so I want to do it with a line laser.I thought convex lens can...
Right Chris,infact I mean parallel beams from the same laser check this(http://www.bitmakers.com/files/imagenes/550_fp_lx2v.jpg)Is it possible to create parallel beams from just a laser pointer with an optical setup?And what kind of setup does this job?
I am trying to build the instrument according to this link http://www.inventgeek.com/2009-Projects/Laser-Instrument/page5.aspx I am having problems with lasers.I can not focus the laser dot on the photoresistor.So I thought about laser array(fabricated)but i could not find it.So I am now...
