Abstract: The present invention provides a terahertz-wave detection element having high spatial resolution in which the occurrence of warping and a crack is suitably suppressed. The terahertz-wave detection element capable of detecting a spatial intensity distribution that an incident terahertz wave has includes: an electro-optic crystal layer consisting of an electro-optic crystal in which a refractive index at an incident position of the terahertz wave changes in accordance with incident intensity of the terahertz wave; and a supporting substrate that supports the electro-optic crystal layer. The terahertz-wave detection element is configured to detect a spatial-characteristics distribution which is generated in probe light irradiated in superposition with the terahertz wave and which corresponds to a spatial distribution of a refractive index generated in the electro-optic crystal layer, thereby to detect the spatial intensity distribution of the incident terahertz wave. A joined part between the electro-optic crystal and the supporting substrate is an amorphous layer consisting of an oxide including a constituent element of the electro-optic crystal and a constituent element of the supporting substrate, and also having a thickness equal to or larger than 1 nm and equal to smaller than 50 nm. A thickness of the electro-optic crystal layer is equal to or larger than 1 µm and equal to or smaller than 30 µm.

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 polarizer (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 utilized 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.

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: To determine the shape characteristics of particles, a light beam (preferably a laser beam) is directed onto a transparent cell containing particles flowing therein and the intensity of the light scattered by the particles is measured with the aid of a photodetector array or a mask containing programmable light valves, comprising one or more concentric rings or parts of rings, at least one of which is provided with one or more isolated segments. The rings and the isolated segments are coupled to an energy meter, the signal amplitudes of which are statistically processed to give amplitude classes. The shape characteristics are determined from a graphical or numerical comparison of the amplitude classes. If at least one ring is subdivided into several segments, calculation of the correlation between the signals from the various ring segments leads to an accurate determination of the average shape characteristics of the particles.
