  Could you elaborate on the caluclation at 3:39? If the target reflects 25% of the nearby fire @ 500, would not the temperature be more than 80? Or am I missing something?

  Hello, thank you for the excellent content you have created about active thermography. I had a question and I would appreciate it if you could answer. Can defects in paint (such as repaints and detecting paint underneath) in the hood area of a car be detected using active thermography and xenon flash when the car has been driven for a distance and the engine is warm?

  I’ve just had a young worker burn his wrist on a vacuum pump discharge line (shiny steel pipe bend) which read 47C. Touch probe read 77C. I think we don’t measure properly because of the emissivity being way less than 1, as per this excellent explanation by the author. My sincere thanks.

  You have said that the detector sees the infrared radiation. But where does this comes from? Does the bike(or any object) emits the infrared radiation or we from the camera incident any light or etc., to reflect it back and measure with it?

• 
  @franklinmontez87333 ай бұрын

  The infrared radiation comes from the heat of the particles. Let's imagine a molecule vibrating (due to heat) in a dense sea of air molecules. When it vibrates, the surrounding molecules will follow up and down due to electromagnetism, like making a wave from lifting a heavy rope up and down. This wave it creates is called an electromagnetic wave, specifically with the infrared wavelength. In fact, if the particle is hot enough the EM wave may be of a visible light wavelength due to a phenomenon called blackbody radiation (but now I'm getting side tracked). When the heat of the particle emits an EM wave, an infrared camera can detect it using a thermocouple. A thermocouple is an electrical device who's power changes depending on its heat. This is how we can record the heat, but then also transmit it to a screen who's pixel color is adjusted based on the power of the thermocouple (which is given by the heat of the object the infrared camera is sensing).

  But they don't detect air; strange.

• 
  @franklinmontez87339 ай бұрын

  that’s because air is made of fast moving gases. they dilute each other to make a homogeneous (evenly distributed) mixture, so the temperatures of air will remain relatively uniform all throughout. the infrared camera would detect differences in temperature, so if you had concentrated hot gas contained near colder gas then it would likely be shown on the camera. think: hot exhaust exiting a car

  @movitherm Is this the physics explanation? I don't think any of 'franks' answer is true. Sounds like a childs guest. The camera will not measure air at any temperature, nor liquid nitrogen (which is 78 % of the air) Why not?

• 
  @franklinmontez87338 ай бұрын

  @@fractalnomics yes, that’s the physics answer. liquids and gases have higher entropy than solids, which favors mixing- heat will be transferred from gases and liquids faster than from a solid (the main reason temp irregularities are easier to see on solids). The temperature IS detected from gases and liquids, but think of it as the background. If for example the temp of the liquid reads green on the infrared camera, then all you’ll see is green (as the heat is spread evenly throughout) and you may go “Hey, it’s all one color. Why is it not detecting temperature!” but it is, and you just can’t see many irregularities.

  I don’t believe this fully answered the question. what is an infrared camera made of? how does each element detect heat? how can the heat be recorded and digitized?

• 
  @movitherm8 ай бұрын

  There are different infrared camera detector technologies available. Each one works a bit different. We essentially differentiate two main categories, micro-bolometer type detectors and quantum well based detectors. The micro-bolometer type has tiny thermocouple elements as pixels that change resistance based on the infrared radiation it is exposed to. The quantum well type actually measures photons in the infrared wavebands. Either the change in resistance or the amount of photons captures is then digitized into a digital count. Some magic sauce is used to convert infrared radiation into temperature and on the software side you can now measure temperature.

  what's the difference between a black hole and a blackbody?

• 
  @movitherm8 ай бұрын

  Hi! Wow - that is a deep and interesting question! A black hole and a black body are two very different concepts in astrophysics and thermodynamics. Black Hole: A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It is formed when a massive star collapses under its own gravity, creating a singularity, a point of infinite density at its core, surrounded by an event horizon beyond which nothing can return. Black holes are characterized by their mass, spin, and charge. They can vary in size from a few times the mass of the sun to millions or even billions of times the sun's mass. Black holes are not objects that emit radiation; they are defined by their ability to trap everything within their event horizon. They can, however, indirectly affect their surroundings by gravitationally influencing nearby matter and light. Black Body: A black body, in the context of thermodynamics and physics, is an idealized object that absorbs all incoming radiation and emits radiation according to Planck's radiation law. It is an ideal absorber and emitter of electromagnetic radiation. A black body does not have to be a physical object; it can also represent a theoretical concept. In practice, objects like a cavity with a small hole, such as an oven or a star, can closely approximate the behavior of a black body. The radiation emitted by a black body is characterized by its temperature, and the spectral distribution of this radiation follows Planck's law, which describes how the intensity of radiation varies with wavelength at a given temperature. In summary, a black hole is a massive, gravitationally collapsed object in space, while a black body is an idealized concept in thermodynamics that perfectly absorbs and emits radiation. They are fundamentally different in nature and have different roles in their respective fields of physics.

  Only problem with flir is their customer service. We had a handheld flir unit that we kept in our car for firefighter admin purposes. Nowhere in the flir manual did it say not to leave it in a car. We called and described the problem, and the agent asked if we left it in the car... Because doing so would cause the issue we were seeing. Since it was outside of warranty, they refused to replace it. Considering their manual omission... They didn't even offer to meet us half way. I asked them if they wanted to maintain this position... Considering they may lose the sale of 30 more of the units. Flir held firm... We will take our business to other thermal providers who exercise common sense customer service. I simply can't justify the purchase price if we can't get more than 2 years of reliable service from flir devices. I hope others have a better experience with their products.

  Will the IR flashlight interfere with the IR camera?

• 
  @movitherm Жыл бұрын

  Hi Kercig! That depends on the wavelength of the flashlight you are using. Most IR flashlights are near IR, or in the range of ~800nm wavelength. That is barely outside of the visible light range. These would not be visible in the thermal camera image at all. Unless, the power from the flashlight is able to warm up the surface. Great question!
