Light doesn't detect anything, no matter what its wavelength is.
If you BUILD a detector that responds to infrared, then your detector will respond to heat.
It can be used to reveal the presence of stoves, people, fresh coffee, dogs, etc., even in the
dark where your eyes cannot detect them.

How does an infrared body scanner work to detect temperature variations in the human body?
An infrared body scanner works by detecting the heat emitted by the human body in the form of infrared radiation. The scanner uses sensors to measure the temperature variations on the skin's surface, which are then converted into a digital image showing different colors representing different temperatures. This allows the scanner to identify areas of the body that may have abnormal temperature readings, indicating potential health issues.
How are x rays and infrared rays used in bar code scanner?
Bar code scanners use infrared rays to illuminate the bar code, which is then read by a sensor that detects the reflected light. X-rays are not typically used in bar code scanners due to safety concerns related to exposure to radiation. Instead, infrared rays are commonly used as they are safe and effective for reading bar codes.
Is far infrared and thermal infrared same?
Far infrared and thermal infrared are both forms of infrared radiation, but they refer to different parts of the infrared spectrum. Far infrared typically refers to the longer wavelength infrared radiation closer to the microwave region, while thermal infrared refers to the mid- to long-wavelength infrared radiation emitted by objects due to their temperature.
How are infrared waves and infrared radiation related?
Infrared waves are a type of electromagnetic waves that carry infrared radiation. Infrared radiation is a form of energy that is emitted or absorbed by objects as heat. Infrared waves have longer wavelengths than visible light and are commonly used in devices such as remote controls and infrared cameras.
What is the common name for infrared radiation?
Infrared radiation, infrared, heat radiation.
Can infrared scanner be worn on the wrist?
Yes, they can
What can infrared scanner not do?
scan packages and detect unusual objects.
What can a infrared scanner not do?
translate a bar code into a computer data file.

What waves are used in an Iris scanner?
In an iris scanner, near-infrared light waves are typically used to capture the unique pattern of the iris. These waves are able to penetrate the outer layers of the eye to create a detailed image of the iris structure, which is then used for identification purposes.
Are there any POS sytems that utilize more than one type of scanner?
Yes, there are ones that use Rfid and infrared.
What has the author Ruth I Whitman written?
Ruth I. Whitman has written: 'Infrared horizon profiles for winter conditions form Project Scanner' -- subject(s): Infrared spectroscopy, Navigation (Aeronautics), Upper Atmosphere
How accurate is the exergen comfort scanner infrared thermometer?
I just got one and i am not running a fever but i have been trying it out and seem's to be working pretty good. say's i am 98.1
What part of the body does a iris scanner look at?
An iris scanner uses visible and near-infrared light to scan the iris of an eye. The iris scanner takes a picture and uses it to compare that to an image already stored in a database to see if there is a match. Since everyone's eyes are unique, iris scanners are becoming more popular for identifying people in security situations.
