    Abstract: A spectroscopic assembly (165) may include a spectrometer (110). The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe (120) to transfer the light reflected from the sample. The light pipe may include a first opening (146) to receive the spectrometer. The light pipe may include a second opening (148) to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.

    Abstract: Apparatus and method are disclosed for the multispectral imaging of features of a scene along an imaging path, from a viewpoint which is arranged to move relative to the scene. The apparatus comprises a first sensing array having a plurality of sensors for acquiring spectral image data of a portion of the scene over a first spectral range and at least one second sensing array having a plurality of sensors for acquiring spectral image data of a portion of the scene over at least one second spectral range. The apparatus further comprises a processor for timing the acquisition of the spectral image data using the sensors of the first sensing array over a first duration, and for timing the acquisition of the spectral image data using the sensors of the at least one second sensing array over at least one second duration, and an integrator for integrating the spectral image data acquired by the plurality of sensors of the first sensing array, and separately, for integrating the spectral image data acquired by the plurality of sensors of the second sensing array. The spectral image data of the portion of the scene is acquired at each sensor of the first and second sensing arrays at temporally separated times within the first and second durations, the temporally separated times being dependent on a relative speed between the viewpoint and the scene, and an angle subtended by a sensor of the associated sensing array and the features within the scene.

    Abstract: A method of identifying an underwater material in an underwater scene comprises analysing a specimen of a material extracted from a body of water using a hyperspectral imager (58) to determine a hyperspectral profile of the material. The hyperspectral profile is stored. An image is taken of an underwater scene in a body of water (22) using the hyperspectral imager (58) or a further hyperspectral imager. An observed hyperspectral profile is generated from the scene. The observed hyperspectral profile is compared with the stored hyperspectral profile to identify the material in the underwater scene. A positive identification is recorded when the comparison is sufficiently close.

    Abstract: A photoacoustic gas sensor, system and method is generally described. In some examples, a photoacoustic gas sensor includes the combination of a grating and a MEMS mirror array operating as a wavelength-selective optical modulator, and a ring array of acoustic sensors arranged around a gas sample region. The MEMS-based optical modulator can be adapted to provide flexible wavelength selectively such that a large number of chemical compounds may be detected. The ring array of acoustic sensors can be adapted to measure photoacoustically generated acoustic signals without the need for resonant enhancement of a photoacoustic cell of the gas sensor. In some examples, a unique uncorrelated and deterministic signal may be used to modulate each light wavelength of interest. Signal processing may be used that allows the simultaneous measurement of the absorption spectra of multiple optical wavelengths as well as the rejection of unwanted acoustic noise.

    Abstract: An apparatus (20) for placement on or in a body of water (22) for hyperspectral imaging of material (24) in the water comprises an artificial light source and a hyperspectral imager. These are arranged so that in use light exits the apparatus (36) beneath the surface of the water and is reflected by said material (24) before re- entering the apparatus (38) beneath the surface of the water and entering the hyperspectral imager. The hyperspectral imager is adapted to produce hyperspectral image data having at least two spatial dimensions.
