3. Near-field scanner - Wikipedia

   en.wikipedia.org/wiki/Near-field_scanner

   Electromagnetic near-field scanner (NFS [1]) is a measurement system to determine a spatial distribution of an electrical quantity provided by a single or multiple field probes acquired in the near-field region of a device under test possibly accompanied by the associated numerical post-processing methods enabling a conversion of the measured quantity into electromagnetic field.

4. Fiber-optical thermometer - Wikipedia

   en.wikipedia.org/wiki/Fiber-optical_thermometer

   The principle of operation is based on the temperature dependence of the bandgap of GaAs. The GaAs crystal fixed on the tip of the fibre will be transparent at a wavelength above 850 nm. The position of the band edge is temperature-dependent and is shifted about 0.4 nm/K. The light is directed via the optical fibre to the crystal, where it is ...

   At visible range (400 nm to 900 nm), about 50% of the incident light can be focused to the tip apex, which is around 5 nm in radius. This hybrid probe can deliver the excitation light through the fiber to realize tip-enhanced Raman spectroscopy (TERS) at tip apex, and collect the Raman signals through the same fiber.

6. Pyrometer - Wikipedia

   en.wikipedia.org/wiki/Pyrometer

   In the 1860s–1870s brothers William and Werner Siemens developed a platinum resistance thermometer, initially to measure temperature in undersea cables, but then adapted for measuring temperatures in metallurgy up to 1000 °C, hence deserving a name of a pyrometer. Around 1890 Henry Louis Le Chatelier developed the thermoelectric pyrometer. [8]
