A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...

In ancient times when someone needed to make a measurement, they would turn to something close at hand, often literally a hand. A tradition that originated thousands of years ago in Egypt that is ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Stanford researchers have unveiled a new type of frequency comb, a high-precision measurement device, that is innovatively small, ultra-energy efficient, and exceptionally accurate. With continued ...

This device is used for contactless scanning and geometrical parameter measurement of the inner diameter of pipes, bushes, holes and tubes among others. It is suitable for large-scale production ...

While it may not rate way up there on a list of life's annoyances, measuring a child's height in the traditional wall-marking fashion can be a tad fiddly. That's where the Kiko comes in, as it uses a ...
