Abstract: The invention relates to a method and a microelectronic sensor device for making optical examinations in an investigation region (3). An input light beam (L1) is emitted by a light source (20) into said investigation region (3), and an output light beam (L2) coming from the investigation region (3) is detected by a light detector (30) providing a measurement signal (X). An evaluation unit (40) provides a result signal (R) based on a characteristic parameter (e.g. the intensity) of the input light beam (L1) and the output light beam (L2). Preferably, the input light beam (L1) is modulated with a given frequency (ω) and monitored with a sensor unit (22) that provides a monitoring signal (M). The monitoring signal (M) and the measurement signal (X) can then be demodulated with respect to the monitoring signal, and their ratio can be determined. This allows to obtain a result signal (R) that is largely independent of environmental influences and variations in the light source.

Abstract: A device implements a method for detecting contamination of an FTIR-based panel. The apparatus generates projection signals representing detection lines that have propagated on a plurality of propagation paths by total internal reflection (TIR) inside a transmissive panel such that contamination on the panel surface causes attenuation (frustration) of at least one of the projection signals. The device generates a transmission value for each detection line in the transmissive panel, and determines the presence of contamination on the surface of the panel by comparing the transmission values according to at least one of the presented comparison techniques.

Abstract: A device (1; 10; 20; 30; 40) for optically examining the interior of a turbid medium (5) is provided. The device comprises an illumination system (2; 12; 22; 32; 42) adapted for illuminating a turbid medium (5) to be examined and an imaging device (106) adapted for generating images from detected light. The illumination system (2; 12; 22; 32; 42) is adapted to be operable in at least a first mode in which a wide area image is acquired by illuminating the turbid medium (5) and a surrounding area. From this wide area image, the region or regions of interest (110) at which the turbid medium (5) is actually situated can be determined. Then, these regions of interest (110) can be illuminated in a second mode. Thus, no light which has not been coupled to the turbid medium (5) and which might cause overexposure of the detector unit of the imaging device (106) will reach the imaging device (106).

Abstract: The present invention relates to a method for monitoring the filling of a capsule with a medicament, to a corresponding filling method, to the associated apparatuses, and to a computer program for controlling the method and the apparatus. In the monitoring method, after at least part of the capsule has been filled with a predefined filling mass of a predefined closed contour of the medicament, at least the filling mass in the part of the capsule after the filling operation is recorded using digital imaging in a first step, the contour of the filling mass in the part of the capsule is determined from the digital imaging recording in a second step, and the contour is analysed in a third step in order to assess the filling operation in comparison with the predefined contour. The invention provides for external influences on the image properties to be compensated for by controlling the optical system.

Abstract: A system for measuring optical detector linearity according to the present invention employs a laser source that illuminates an integrating sphere. The sphere randomizes the laser signal phase and produces a uniform intensity over the sphere output. A collimator expands the sphere output for entry into an interferometer, where the incident optical energy is amplitude modulated in a sinusoidal fashion by a linear mechanical mirror movement. Optical band filters eliminate significant harmonic content being present on a pre-detected optical signal. Sampling of the detected signal energy is performed synchronous to the mechanical mirror position to assure sinusoidal response. The sampled signals are processed to separately determine signal harmonic components attributed to detector non-linearity and multiple laser reflections within the system. The system utilizes at least two measurements at two different laser intensities. An optional third measurement of background radiance may be applied to the first two measurements to enhance accuracy.

Abstract: An apparatus for enhancing the selectivity for spectroscopic measurements of analytes in a turbid medium is described. In one example, spatial filters are used to select only certain radii from the medium to be imaged. This selection is accomplished by placing an optical obstruction on the surface of the medium or at an image plane of the surface later in the optical imaging system. In one implementation, this is achieved by placing a fiber bundle at an image plane of the collecting optical system and then using a spacer of appropriate size at the center of the fiber bundle to act as a central obstruction.
