Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

Several factors are driving the popularity of optical fiber cabling. Chief among those is the growth of high-tech applications that require the massive bandwidth fiber-optic cabling makes possible.
