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 ...

Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get adjusted ...

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 ...

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 ...

Today's consumer devices are defined by portability. However, where these designs incorporate movement, how do product engineers integrate feedback? In portable medical applications, reflective ...

Hamamatsu Photonics has recently developed a new reflective sensor named P13567-02CT. The sensor is designed to work with near-infrared/proximity types and is packaged in a compact size. It contains ...
