    Abstract: A handheld optoacoustic probe includes an ultrasound transducer array and optical fibers with a first end formed into a fiber bundle providing an input and a second, distal end providing an output. A light bar guide retains the distal end of the optical fibers on the same plane. One or more optical windows may be associated with, and spaced from the light bar guide so as to prevent contact between a coupling agent and the distal ends of the optical fibers, thus mitigating a potential acoustic effect of the coupling agent in response to light emitting from the fibers. A silicon rubber acoustic lens doped with TiO2 may be provided, with a reflective metal surrounding the outer surface of the acoustic lens. A handheld probe shell houses the light bar guide, the ultrasound transducer array, and the acoustic lens.

    Abstract: In the application, the change in the magnetic state of the haemoglobin caused by the malarial infection is exploited by detecting suitable properties of haemozoin which are dependent on the application of a magnetic field. FIG. 1 shows apparatus, shown generally at (10), for performing magneto-optical detection using photo-acoustic techniques. The apparatus (10) comprises a light source (12), producing a beam of optical radiation (14) which passes through a polariser (16), a variable LC retarder (0 or 180° retardance) (18), and a (chopper 20), before impinging on a sample (22) held in a sample holder (24). The sample is in direct contact with an acoustic detector (26). The apparatus (10) further comprises an electromagnet (28), and a Gauss meter (30) can be utilised to measure the applied magnetic field strength. Advantages associated with this approach are the—possibility of making in vivo measurements, and the avoidance of problems of optical scattering associated with conventional optical measurements on turbid liquids such as whole blood.

The body tissue interface is adapted to contact body tissue and to deliver light from the infrared light source to the contacted body tissue. The detector is adapted to receive spectral information corresponding to infrared light transmitted through the portion of body tissue being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit is adapted to compare the electrical signal to an algorithm built upon correlation with the analyte in body fluid, the algorithm adapted to convert the received spectral information into the concentration of the analyte in at least one body fluid.

    Abstract: A polarization modulation photoreflectance technique has been developed for optical characterization of semiconductor quantum confined structures. By using a tunable laser source in conjunction with polarization state modulation, a single beam modulation spectroscopy technique may be used to characterize the optical response of semiconductor materials and structures. Disclosed methods and instruments are suitable for characterization of optical signatures of quantum electronic confinement, including resolution of excitonic states at the band edge or other direct or indirect critical points in the band structure. This allows for characterization of semiconductor quantum well structures, for characterization of strain in semiconductor films, and for characterization of electric fields at semiconductor interfaces.

    Abstract: Optical imaging of an object utilizes a plurality of amplitude modulated light rays propagating through the object, either sequentially or simultaneously, for detection by a single photodetector. The light rays may propagate geometrically (i.e., directly) or diffusively. Each of the rays is encoded with a different phase to provide sufficient information for decoding the light intensity detected by the photodetector. The rays may be applied simultaneously in an array, in which case different carrier frequencies as well as different phases are applied to the different rays by any of a number of modulators. Alternatively, the rays may be individually applied to the object in a sequence of phase encoded rays. In either case, the single photodetector receives sufficient information to image each of the voxels of interest in the object being imaged. Information may be obtained for different voxels selected for imaging without mechanical scanning.
