A system is provided that includes a cavity ring-down spectrometer and a processor. The spectrometer is configured to pass, through a cavity resonator, a modulated, continuous-wave electromagnetic signal at each of one or more selectable, transmission frequencies in the Terahertz region of the electromagnetic spectrum. The spectrometer includes a transmitter that, with the cavity resonator, is configured so as to excite a single resonant mode of the cavity resonator. The processor is configured to receive a measurement of the passed portion of the modulated electromagnetic signal, and determine a phase shift of the modulated electromagnetic signal based upon the measurement. The processor is then configured to calculate a ring-down time of the cavity resonator as a function of the phase shift.

A system for suppressing noise by frequency dither includes a transmitter, receiver and a frequency dither circuit, as well as a cavity along a propagation path of the electromagnetic signal between the transmitter and the receiver. The transmitter is configured to transmit an electromagnetic signal to the receiver at each of one or more selectable frequencies. The frequency dither circuit is configured to apply a frequency dither to the electromagnetic signal transmitted from the transmitter to the receiver at each of the selectable frequencies. In this regard, the applied frequency dither has a span having been selected as a function of a minimum frequency period of an expected standing wave in the system, and a rate having been selected as a function of a signal processing bandwidth for sampling a frequency spectrum including the selectable frequencies.

A method is provided that includes receiving and processing a sample signal scan. Processing the sample signal scan includes applying an inner-product operation on the sample signal scan and each of a plurality of eigenvectors to generate a plurality of corresponding coefficients, and subtracting the sample signal scan from a linear combination of the eigenvectors and corresponding coefficients to thereby produce a corrected sample signal scan. In this regard, the eigenvectors have been generated by decomposing a plurality of background reference signal scans according to a singular value decomposition technique. The signal scans include a plurality of electromagnetic signal measurements at a discrete set of frequencies, where each measurement has been taken by a spectrometer system passing an electromagnetic signal through a sample cell including just a base medium (for the background reference signal scans), or both a base medium and a sample medium (for the sample signal scan).

An apparatus is provided that includes a field reflector and a plurality of pairs of object reflectors. The apparatus also includes a plurality of source and detector port pairs, where each source port is configured to pass a beam of radiation, and each detector port is configured to receive a beam of radiation. The source and detector ports of each pair are positioned proximate an outer edge of the field reflector such that an optical axis of the field reflector lies between the respective source port and detector port. The object reflectors and source and detector port pairs are arranged such that each source and detector port pair is associated with a respective pair of object reflectors forming a distinct channel, where the source and detector port pair, and centers of the associated pair of object reflectors, of each channel lie in a distinct plane.

A system for processing signals includes a receiver assembly for receiving a signal. The signal has a sample component with a sample electric field and a sample polarization, and has a reference component with a reference electric field and a reference polarization. The receiver assembly includes an analyzer for polarimetrically processing the signal, including differencing the signal to generate a difference electric field proportional to the difference of the sample and reference electric fields. By polarimetrically differencing the signal, the analyzer reduces the magnitude of the common-mode signal at the difference signal receiver. The receiver assembly includes an electric-field detector for measuring the difference electric field such that the reduction in common-mode amplitude decreases the noise equivalent power of the electric-field detector. One advantage of the present invention, then, is the reduction of noise equivalent power of the electric-field detector when measuring small variations in large electric fields.

An optical head for a Raman spectroscopy system includes a housing an input configured to allow input radiation of a selected wavelength into the housing, a first lens disposed in an end of the housing to allow the input radiation to emit from the housing through the first lens and to receive reflected radiation including specular reflection and diffuse reflection, and a second lens disposed in the housing and configured to receive reflected radiation from the first lens. The optical head includes an output configured to receive the reflected radiation from the second lens. The optical head includes a blocking mirror disposed in the housing between the first lens and the second lens. The blocking mirror is configured and positioned to direct the radiation from the input to the first lens. The blocking mirror blocks at least a portion of specular reflection from reaching the second lens but allows diffuse reflection to the reach the second lens.
