OD200 succeeds in achieving significantly more accurate measurements on challenging surfaces. The OD200 delivers more stable ...

Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

A low-cost, simple, noncontact displacement sensor using the self-mixing effect inside a cw single-mode laser diode has been developed for modal analysis and defect detection. The resonance ...

We propose a simple optical interface for coupling between a single mode fiber and a grating on a Photonic Integrated Circuit (PIC), by coupling from the back side using a ball lens. This way, the top ...
