  • Patent number: 12019018
    Abstract: A full-field microscopy method for detection of Brillouin-scattered light includes illuminating a two-dimensional plane in a sample with interrogating light having a first wavelength. Light emitted from the two-dimensional plane can be collected. The emitted light comprises Brillouin-scattered light resulting from interaction of the interrogating light with the sample. The Brillouin-scattered light can have a second wavelength shifted from the first wavelength. The collected light can be passed through a spectrally-selective assembly comprising a gas or vapor illuminated by pumping light. After the spectrally-selective assembly, the Brillouin-scattered light from multiple points in the two-dimensional plane in the sample can be simultaneously detected by an electro-optical sensor. In some embodiments, the spectrally-selective assembly can be altered by changing a wavelength or polarization of the pumping light to allow acquisition of a Brillouin spectrum.

  • Patent number: 11977030
    Abstract: Disclosed herein are systems and methods of obtaining a derivative Raman spectrum using an excitation or Raman pump beam whose wavelength is modulated in any suitable manner such as, for example, stochastically. Shifting the wavelength of the input excitation by a small amount in approaches like SERDS can isolate the Raman scatter from other spectral artifacts and reduce the false detection rate. For example, an input excitation sequence can be correlated with the response of an individual pixel of a detector. From this, pixels that have captured Raman scattered photons can be separated from pixels capturing non-Raman photons. These techniques can be expanded to other fields and/or types of spectroscopies that utilize a dispersive element detector with time-dependent spectral features.

In one embodiment, the unmodulated reference optical signal is transmitted through the same vapor cell as a modulated pump optical signal. As such, the unmodulated reference optical signal experiences absorption by the vapor, which converts laser phase noise to amplitude noise like the other optical signals passing through the vapor cell. In one embodiment, the unmodulated reference optical signal has an optical path in the gas cell that is offset (or non-crossing) from the optical path of the modulated pump optical signal. The unmodulated reference optical signal allows removal or mitigation of the noise on the other optical signal.

  • Patent number: 11898959
    Abstract: Raman systems and methods use advantages offered by increased laser mobility/path length and photon migration to analyze diffusively scattering solids, including pharmaceuticals. A collimated laser excitation beam having a first diameter induces from a sample a backscattered collimated Raman collection beam with a second diameter. The collimated laser excitation beam and the collimated Raman collection beam form a counter-propagating collimated optical path, and the collimated laser excitation beam is preferably smaller in diameter than the diameter of the backscattered collimated Raman beam. The collection beam to a spectrograph for Raman analysis of the sample. A Raman calibration standard may be placed in the collimated optical path, and/or the sample may be supported in a reflective holder that may be at least partially spherical and/or may form part of a multi-well plate. The counter-propagating collimated optical path may be contained within a Raman microscope.

  • Patent number: 11808698
    Abstract: A device for the detection of analytes comprises a substrate (10) with nano-antennas (11,12). The nano-antennas (11,12) comprise an antenna material (11m, 12m) for forming resonant antenna structures which receive and resonantly interact with source light (L0) to form respective resonance peaks (R1,R2) over a resonant wavelength range (A1,A2) overlapping respective signature wavelength (?1,?2) of a target analyte (A). The resonant interaction causes a locally concentrated field (Ec) of the source light (L0) in the resonant wavelength range (?1,?2). The concentrated intensity (Ic) is localized around a respective target location (T1,T2) which is provided with a sorption material (11s, 12s) that sorbs the target analyte (A). This provides a locally increased analyte concentration (Ac) of the target analyte (A) coinciding with the locally concentrated field (Ec) of the source light (L0). Accordingly, the interaction of the source light (L0) with the target analyte (A) is enhanced.
