    Abstract: An optical pulse generating apparatus that supplies pump light and probe light includes a light source and a modulation unit configured to modulate light emitted from the light source, thereby dividing the light into the pump light and the probe light. The modulation unit is configured such that a frequency for modulating the light is variable. The modulation unit changes a difference between a moment of the pump light incident on an object and a moment of the probe light incident on the object by changing the frequency.

    Abstract: An optical detection apparatus used for detecting a tissue includes a light-emitting unit, a spectroscopic unit and a light-sensing array. The light-emitting unit emits light entering into the tissue. The spectroscopic unit receives the light outputted from the tissue and divides the received light into a plurality of rays with different wavelengths. The light-sensing array senses the rays outputted from the spectroscopic unit so as to generate an array spectrum. By the spectroscopic unit, the detection of the rays of multiple wavelengths can be performed without using plural light-emitting diodes for emitting light of different wavelengths. Besides, the user can perceive the detection result (e.g. the location of the abnormal tissue) intuitively by integrating the light-sensing array and the spectroscopic unit.

    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 system for determining the concentration of an analyte in at least one body fluid in body tissue comprises an infrared light source, a body tissue interface, a detector, and a central processing unit. 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: In one aspect, a diagnostic test system includes a housing, a reader, and a data analyzer. The housing includes a port for receiving a test strip. The reader obtains separable light intensity measurements from localized regions of an area of the detection zone exposed for optical inspection, wherein each of the localized regions is characterized by at least one surface dimension smaller than the first dimension. The data analyzer identifies ones of the light intensity measurements obtained from the at least one test region and computes at least one parameter from the identified ones of the light intensity measurements. In another aspect, the reader obtains a respective set of light intensity measurements from each of multiple corresponding regions of the exposed surface area of the detection zone, and the data analyzer computes at least one parameter from at least one of the sets of light intensity measurements.
