    摘要: An optical probe for use in infrared, near infrared, Raman, and other spectrometers includes a probe outer surface with a cavity defined therein. The probe emits light into a sample via emission locations on the probe outer surface, at least one being in the cavity. The light emitted into the sample is then collected at collection locations which include at least two of (a) a reflectance collection location situated on the probe outer surface for collecting diffusely reflected light from any adjacent sample; (b) a transmittance collection location situated in the cavity and receiving light transmitted across the cavity from an emission location situated on an opposite side of the cavity; and (c) a transflectance collection location situated in the cavity and receiving transflected light emitted from an emission location in the cavity, with such light being reflected from a side of the cavity opposite the transflectance collection location.

    摘要: We describe a method of selectively detecting the presence of an analyte. The method comprises providing a waveguide with a core comprising porous material; absorbing an analyte sample into the porous material of the core such that the analyte sample is held within pores of the core; waveguiding radiation along the waveguide to an output; measuring spectral features of the output radiation due to absorption or scattering of said waveguided radiation by the absorbed analyte sample; and selectively identifying the presence of a target analyte in the sample from the spectral features. In embodiments spectral features are measured for multiple different waveguide core regions having different physical/chemical properties modified to provide additional selectivity to the target analyte(s), and these measurements are combined to identify the target analyte.
