Abstract: A system for determining an analyte concentration in a fluid sample (e.g., glucose) comprises a light source, a detector, and a central processing unit. The detector is adapted to receive spectral information corresponding to light returned from the fluid sample 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 is adapted to convert the received spectral information into the analyte concentration in body fluid. Spectral information is delivered from the central processing unit to the light source and used to vary the intensity and timing of the light to improve the accuracy of conversion into analyte concentration.

Abstract: The arrangement for examining microscope preparations with a scanning microscope comprises a laser (1) and an optical means (12) which images the light generated by the laser (1) onto a specimen (13) that is to be examined. Provided between the laser (1) and the optical means (12) is an optical component (3, 20) that spectrally spreads, with a single pass, the light generated by the laser (1). The optical component (3, 20) is made of photonic band-gap material. It is particularly advantageous if the photonic band-gap material is configured as a light-guiding fiber (20).

Abstract: A spectrometer for infrared reflectance measurements of samples for identification of the sample materials is built into a steering wheel assembly. The spectrometer includes a window and optics on a bench adjacent the window, so that the optics will be aligned with the sample when the device is placed in optical alignment with or directly against the sample. The optics include a broad-band IR light source (ordinary lamp) shining onto an acousto-optic tunable filter (AOTF), which passes narrow-band IR light with a swept frequency; a lens focusing the IR through the window onto the sample; and a reflectance detector aligned with the window of the spectrometer to pick up reflected light. A computer, which may be mounted in the spectrometer, compares the detected reflectance spectrum with stored sample data spectra, and identifies the material or the components of the material and their proportions. When a control substance is detected an alarm signal is produced.
