A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...
Faster and more sensitive than no-lens device, RoHS-compatible detector reduces assembly costs Providing a high-sensitivity infrared detector capable of fast response times, the OP570 Series silicon ...
A single phototransistor mimics retinal bipolar cell function while detecting visible and infrared light, enabling low-power image processing through programmable ON and OFF photoresponses. (Nanowerk ...
Marktech had revealed the latest in its line of sensors which combine many LEDs of different wavelengths with a photodiode. MTMD142345PDT38 has five LEDs at 1.04, 1.2, 1.3, 1.46 and 1.55μm, plus an ...
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 ...
The OptoHiT™ FODM8801 is a first-of-its-kind phototransistor, utilizing Fairchild’s leading-edge, proprietary process technology to achieve high operating temperature characteristics, up to 125°C. The ...
[Arao] wanted to measure the RPM of a spinning wheel using parts that he could scavenge from his junk box. A bit of thought led him to build a reflective sensor which can measure the spinning of a ...
Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...
