Infrared Sensitivity - Diffraction Limited

Infrared Sensitivity. CCD and CMOS sensors are very sensitive to near-infrared (IR) light. Although this can be helpful in obtaining the maximum sensitivity, it can also present a few challenges. When monochrome CCD cameras are used with filter wheels, an IR cut filter is often used because typical blue filters leak in the infrared.

What is an IR sensor? | FierceElectronics

Jul 29, 2019· Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).

arduino - Reducing the sensitivity of a PIR sensor ...

Jan 10, 2016· The lens provides multiple benefits to the sensor, by dividing the field of view, providing a wider angle, and focusing IR into the sensor. No lens, no benefit. This should be enough to both narrow it's view, and weaken it's sensitivity to distance. If you want a single foot of distance, then try this before taking a soldering iron to the module.

Threshold Sensitivity of the Mid-IR Sensors

The proposed "vector" noise description method was used to optimize the A3B5 sensor design elements and to estimate the value of their threshold sensitivity at the required speed of operation. As an example of promising A3B5 sensor application in the measurement technologies, the metrological characteristics of these sensors estimated for infrared

What is an IR sensor? | FierceElectronics

Jul 29, 2019· An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the ...
