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

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

Avago Technologies has announced a series of small form factor (SFF) optical mouse sensors with an integrated chip-on-board (COB) LED illuminated optical navigation system that is the thinnest in the ...

Currently, Kyocera’s technology enables aerial images whose focal positions vary by wavelength. In the future, increasing the ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

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 ...
