Abstract: A variable synthetic wavelength absolute distance measuring device locked to a dynamic sideband and a method thereof are disclosed. A high-frequency electro-optic phase modulator driven by an adjustable clock source to modulate a single-frequency reference laser to generate laser sidebands with equal frequency intervals. The tunable laser is locked to the fifth-order sideband through an offset frequency locking technology. After locking, the interval frequency of the sideband is determined by the adjustable clock source, namely dynamic sideband. The frequency of the adjustable clock source is dynamically adjusted, the interval frequency of the sideband and the frequency difference between the two lasers will change accordingly. Combined with the multi-wavelength interferometry, the constructed synthetic wavelength is also determined by the adjustable clock source, that is, the variable synthetic wavelength.

Abstract: The invention offers high resolution and accuracy for nanoscale temperature mapping. Instead of collecting light after emission in near-field that decays to far-field, the present invention directly couples the near-field waves to a polaritonic-coated infrared probe. The polaritonic coating can be formed on an IR-tuned optical fiber to receive the coupled IR radiation and form polaritons, including plasmons or phonons, using the IR polaritonic material. The IR polaritons propagate along the probe decay back into the fiber core without substantial losses to far-field and are transmitted to a detector, such as a spectroscope. The coupling of the near-field energy to emission detected through the tip apex of fiber can be expressed as emission spectra. Through mapping with other spatial points, multi-dimensional displays and other information can be provided. The resolution can be less than 100 nanometers, such as at least an order of magnitude less than 100 nanometers.

Abstract: The invention provides apparatuses and systems for cutting off electromagnetic radiation (ER) beams, such as laser beams. The apparatuses and systems employ gravitational force on a shutter to close off the path of the ER beam if power is cut to an electromagnet holding the shutter out of the beam path. Power to the electromagnet is typically connected to a safety interlock connected to a door or other entry point to an enclosure in which the ER beam is being used. Additionally, the invention provides add-on devices that allow the ER beam to be blocked to change lenses or targets.
