DVD Drives Turned Into Microscopes

With the advent of streaming products and services, lots of persons are opting to forego the selection of actual physical media. In convert, there are now a good deal of optical drives sitting unused in elements bins and old personal computers. If you’d like a little something beneficial to do with this now-out of date technological innovation, you can have a try out at turning one particular into a laser microscope.

This create demands two DVD pickups. By scanning when horizontally and when vertically and measuring the returning gentle from the DVD laser, an impression can be developed. For this establish, the next pickup is utilized to move the object alone. The full product is managed by an Analog Discovery 2, although this basic principle could be ported to other microcontroller platforms. Many thanks to the exceptionally good laser in a DVD and the exact movements of the motors observed in the control machinery, the photographs attained making use of this system have the probable to be a lot more in-depth than equivalent obvious light-weight microscopes.

While this is not pretty scanning electron microscope territory, it’s good plenty of to plainly picture the inner workings of a de-capped integrated circuit. Anything like this could be indispensable for reverse-engineering ICs or troubleshooting other comparably compact electronics, with resolutions better than can generally be acquired with visible mild microscopes. We’ve even viewed very similar builds in the earlier which build microscopes like this as dedicated lab equipment.
