When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...

The reflective properties of plastic make it a notorious offender in this regard. The problem even extends to those objects covered in shrink wrap. Polarizing filters help block false readings from ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

Everyone is familiar with pinwheels, and few of us haven’t crafted one from a square of paper, a stick, and a pin. Pinwheels are pretty optimized from a design standpoint, and are so cheap and easy to ...

Capable of integrating infrared, visible light, or VSCEL sensing capabilities in a single package, the OPB608 series reflective sensors can detect objects at distances up to 2". Each component in the ...

Marktech Optoelectronics has announced the expansion of its surface-mount family of SWIR reflective sensors. The sensors are suitable for position sensing and detection applications, including card, ...

Once you have a track and a kart to race on it, what’s missing? A lap counter that can give your lap times in hardcopy, obviously! That’s what led [the_anykey] to create the Arduino-based Lap Timer to ...
