I've decided to go with the TIM-209-1 at 1mW with wavelength at 650nm, I would expect this to be sufficient. I am just having issues on how to get collimating lenses to focus the laser into the grooves of the record, any ideas on where I should start? I like the idea of focusing the laser into...
Thanks elect_eng for your input.
You've raised quite a few valid points I have to take into consideration. I have found the needle size to be 0.2mil x 0.7mil. I've actually shortlisted a couple of laser diodes to be used here, but having presented these to my supervisor, he suggested cutting...
Hi dlgoff
Thanks for the reply!
My project revolves around utilizing the principle of laser interferometry to read tracks off vinyl records, instead of using a needle and piezoelement. I chose this project, even though I major in power engineering, because I've always been enthusiastic and...
Hi all
Im doing work on laser interferometry for my final project,just wondering if there are any experts or experienced people in this field here,thanks much!
