We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Fig 4. Exposing the modified pressure sensor to laser energy created a temperature-induced change in the piezo-resistive element’s resistance that corresponded directly to laser power.

Ophir Photonics Group, global leader in precision laser measurement equipment and a Newport Corporation company, today announced four new thermal laser sensors designed for measuring high pulse ...

A high-resolution velocity profile sensor developed in Germany could improve the design of airplane turbines. Conventional laser Doppler anemometry systems measure an averaged velocity in a small ...
