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 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...

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 fundamental difficulty of working with nanoparticles is that your objects of study are too small for an optical microscope to resolve, and thus measuring their size can be quite a challenge. Of ...
