Abstract: A non-destructive method for chemical imaging with ˜1 nm to 10 μm spatial resolution (depending on the type of heat source) without sample preparation and in a non-contact manner. In one embodiment, a sample undergoes photo-thermal heating using an IR laser and the resulting increase in thermal emissions is measured with either an IR detector or a laser probe having a visible laser reflected from the sample. In another embodiment, the infrared laser is replaced with a focused electron or ion source while the thermal emission is collected in the same manner as with the infrared heating. The achievable spatial resolution of this embodiment is in the 1-50 nm range.

Abstract: The reported invention belongs to spectral interference devices and can be used for spectral research in various fields of technology.The objective of the present invention is to improve the optical characteristics of the spectrometer in which reduced loss of light from the radiation object on aberration is attained with a minimum number of optical elements produced at lower costs.The objective is achieved by the fact that the static Fourier spectrometer contains an input collimator optically coupled with the interferometric unit consisting of a beam splitter and at least two mirrors installed with the ability to create an interference image localized in the plane of the mirrors, and an image recording device optically coupled with the interferometric unit by means of the projective system with the ability to project the figure of the indicated interference image on the image recording device. Besides, the projective system includes a spherical mirror and an objective lens centered against the normal line to the optical surface of the mirror. The mirror and the objective lens are produced to enable optical radiation to pass through the objective lens from the interferometric unit to the spherical mirror, being reflected from it and passing through the same objective lens to the recording device.

Abstract: A spectrometer for identifying an analyte material. One embodiment of the spectrometer includes a single ultrashort pulsed laser (USPL) source, a fiber interferometer, a frequency converter and a transceiver. The USPL source is configured to generate a laser beam. The interferometer is operatively coupled to the USPL source, and is configured to split the laser beam into a first laser beam and a second laser beam, providing a variable difference in lengths between the paths of the first laser beam and the second laser beam. The spectrometer then electronically scans the variable-path second laser beam over the first laser beam to generate interferogram patterns. The frequency converter is configured to receive the interferogram patterns from the interferometer, and perform a frequency conversion of the interferogram patterns to form an output beam. The transceiver is configured to transmit the output beam and to receive radiation from the analyte material. The radiation is thereafter used to identify the analyte material.

Abstract: This invention relates generally to the systems and methods for standoff trace chemicals detection such as explosives residue and others, and particularly to optical devices and the methods of their use based on sensing of gases and residue materials. This sensing includes detection and measurement of optical absorption spectra and relative concentration of the chemical followed by the chemical identification based on these spectral data. The sensing is based on photothermal interferometry method improved by implementation of coherent optical detection. The coherent optical detection is performed by an integrated polarization-diversity coherent receiver with an electro-optic phase modulator for a local oscillator optical beam. The implementation of pulsed probe sensing and local oscillator optical beams in the coherent detection improves the device with better eye safety performance. The hybrid calibration via a phase-modulated local oscillator optical beam allows optimizing the signal reception and reduces complexity of the probe subsystem.

Abstract: A method and system are presented for determining a line profile in a patterned structure, aimed at controlling a process of manufacture of the structure. The patterned structure comprises a plurality of different layers, the pattern in the structure being formed by patterned regions and un-patterned regions. At least first and second measurements are carried out, each utilizing illumination of the structure with a broad wavelengths band of incident light directed on the structure at a certain angle of incidence, detection of spectral characteristics of light returned from the structure, and generation of measured data representative thereof. The measured data obtained with the first measurement is analyzed, and at least one parameter of the structure is thereby determined. Then, this determined parameter is utilized, while analyzing the measured data obtained with the second measurements enabling the determination of the profile of the structure

Abstract: The present invention is directed to an assembly for use in detecting an analyte in a sample based on thin-film spectral interference. The assembly comprises a waveguide, a monolithic substrate optically coupled to the waveguide, and a thin-film layer directly bonded to the sensing side of the monolithic substrate. The refractive index of the monolithic substrate is higher than the refractive index of the transparent material of the thin-film layer. A spectral interference between the light reflected into the waveguide from a first reflecting surface and a second reflecting surface varies as analyte molecules in a sample bind to the analyte binding molecules coated on the thin-film layer.
