  • Sensor Sense: Passive Infrared-Motion Sensors
    Passive infrared (PIR) sensors detect infrared energy radiating from objects within their field of vision. Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its "passive " name suggests, it responds only to infrared energy radiated by the object
  • Lighting the Way for Vision
    designing robust vision inspections. An object or target must have enough optical contrast for a vision sensor to see it. Put another way, there must be a detectable change (or delta) in the light received from the target compared to everything else in the camera 's field-of-view (FOV). Controlled
  • Machine Vision Adds Capacity, Safety to Road 'Well-Traveled'
    Ambient light has been a challenge for machine vision cameras and systems, which had their genesis in the more controlled environments of the industrial production floor. "The most common solution is to use infrared (IR) light and use a silicon sensor without the typical NIR filter-coating applied
  • Cameras at work
    . Infrared cameras typically handle heat-mapping applications but also work well when ambient light may vary widely and analysis is sensitive to the change. Though designed for visible spectrum light, many CCDbased cameras also work in the infrared spectrum. The selection of imaging sensor or imager
  • Trash in, cash out
    transports the material under an optical sensor where it is illuminated by near infrared light. Software analyzes captured images and flags plastic objects for removal by air jets. Certain optical scanning systems can also identify and remove a specific type of plastic, say, PET (polyethylene
  • Medical Device Link .
    equipped with batteries, a power and wavelength sensor, and a connecting cable. In addition to providing ultraviolet to far infrared photonic components, the company supplies a range of other detectors and instruments, including voltage and lock-in amplifiers, IR spectrometers, and laser proximity
