Hochauflösende Infrarotmessungen für Profis (CC2tv Folge 393)

Website: https://www.cc2.tv Donate: https://paypal.me/cc2tv The FLIR ONE® Pro is a thermal imaging camera designed as an accessory for smartphones, enabling technically sophisticated measurements in the infrared range. The device utilizes a high native resolution, resulting in good image sharpness. Image enhancement is supported by the FLIR VividIR system, which allows for a more precise representation of temperature distribution. The camera can measure temperatures up to 400°C (752°F) and has a temperature resolution of 70 mK, allowing even small temperature differences to be captured. It is equipped with an integrated set of measurement tools that enable detailed analysis of thermal conditions. The FLIR ONE® Pro is available for use with iPhones and Android devices. Further information on compatibility with additional mobile devices and technical specifications can be found on the manufacturer's website. www.flir.com/products/flir-one-pro https://www.flir.com/discover/thermal... https://www.flir.com/support-center/ Further information on the topic: Thermal radiation and infrared radiation are related but different phenomena. Thermal radiation refers to the entire spectrum of electromagnetic waves emitted by bodies based on their temperature. Every body above absolute zero emits this radiation, with the dominant wavelength varying depending on the temperature. This spectrum encompasses both the visible and infrared regions. In contrast, the term infrared radiation describes a specific portion of this spectrum, ranging from approximately 780 nanometers to 1 millimeter and is often divided into near (NIR), mid (MIR), and far (FIR) infrared. At ordinary ambient temperatures, the majority of the radiated energy lies in the infrared range, which is why the terms are often used synonymously in everyday life—a distinction that is, however, important for precise physical analyses and technical applications. The generation of thermal radiation is closely linked to molecular motion. The disordered movement of atoms and molecules converts kinetic energy into electromagnetic waves. The temperature of a body correlates directly with the average kinetic energy of its particles, as illustrated by the equation E = (3/2) k T (where k is the Boltzmann constant and T is the absolute temperature). As temperature increases, the intensity of thermal radiation increases according to the Stefan-Boltzmann law, while the emission maximum is shifted to shorter wavelengths at higher temperatures (Wien's displacement law). A practical example of these relationships is the microbolometer, which is used in infrared imaging technology. A microbolometer cell consists of several components: 1. A membrane – a thin, thermally insulated layer that absorbs infrared radiation. 2. A sensor layer – usually made of amorphous silicon or vanadium oxide, whose electrical resistance changes with temperature. 3. Electrodes – for measuring the change in resistance. 4. Bridges – which connect the membrane to the substrate and provide additional thermal insulation. 5. A reflector – below the membrane, which reflects unabsorbed radiation. 6. A substrate – which contains the readout circuit (ROIC). When infrared radiation hits the membrane, it heats up, changing the resistance of the sensor layer. The electrodes measure this change, and the readout circuit converts the signal into a digital image. To optimize absorption, the distance between the membrane and the reflector is set to approximately one-quarter of the wavelength to be detected.
