    摘要: A radiation detection system (100) is described comprising a measurement region (104) in a measurement chamber adapted for receiving at least one sample (108) to be examined and adapted for receiving excitation radiation for impingement on the at least one sample (108) and for generating sample radiation. The radiation detection system (100) furthermore comprises at least one detector element (106) for detection of the generated sample radiation. The radiation detection system thereby is a front irradiation system, i.e. the excitation radiation is incident on a first side of the measurement region (104) in a measurement chamber and the at least one detector element (106) is positioned at a second side of the measurement region (104) in a measurement chamber, the second side being opposite to the first side with respect to the measurement region (104) in a measurement chamber, such that detection occurs at the side facing the first side. The detection system (100) also comprises optical means (112) adapted for guiding said excitation radiation aside the at least one detector element (106).

    摘要: A detection system (100, 150, 180, 200, 220, 250) for detecting luminescence from at least one sample (108) when excited by incident excitation radiation. Detecting luminescence may allow to detect, for example, biological, chemical or bio-chemical particles.

    摘要: The present invention provides a sensor and a method for detecting an optically variable molecule (9) in a sample (3). The sensor comprises an excitation radiation source (1) for irradiating the sample (4) and exciting the optically variable molecule (9), thus generating a luminescence signal (7). The sensor furthermore comprises a modulation means (4) for modulating the excitation radiation beam (2) in a direction different from, preferably substantially perpendicular to, a scanning direction of the excitation radiation beam (2) over the sample (3). The method and sensor according to the invention lead to an improved signal-to-noise ratio by reducing and even minimising the background signal in the luminescence signal (7) and to an improved accuracy by minimising signals coming from false-positives.

    摘要: A system and method for non-invasive measurement of glucose concentration in a live subject including a thermal emission spectroscopy (TES) device 10, an optical coherence tomography (OCT) device 20 or near infrared diffuse reflectance (NIDR) device. The TES 10 generates a signal indicative of the absorbtion of glucose, from which the blood glucose concentration is determined and the OCT device 20 generates a signal indicative of the scattering coefficient of a portion of the live subject, from which the blood glucose concentration is determined. The signals generated by the TES and OCT devices along with signals generated by sensors for measuring the body heat and surface temperature of the subject are used in the metabolic heat conformation (MHC) method of determining blood glucose concentration. The system may include a photoacoustic sensor for generating a signal indicative of thermo-elastic skin properties from which the blood glucose concentration is also determined.
