    Abstract: A system (10) for determining the concentration of an analyte in at least one body fluid in body tissue (52) comprises an infrared light source (20), a body tissue interface (34), a detector (58), and a central processing unit (78). The body tissue interface (34) is adapted to contact body tissue (52) and to deliver light (14) from the infrared light source (20) to the contacted body tissue (52). The detector (58) is adapted to receive spectral information corresponding to infrared light (56) transmitted through the portion of body tissue (52) being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit (78) 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: The invention makes it possible to measure a calorie by using near-infrared rays, thereby realizing calorie measurement of an object to be quickly and easily performed using a non-destructive method. A device of measuring calorie of an object includes an object holding unit (1) including a table (2) on which an inspection-target object (M) is placed; a light source unit (20) that supplies light in near-infrared regions to irradiate the inspection-target object (M) placed on the turning table (2); a light reception unit (30) that receives light reflected from or transmitted though the object (M); and a control unit (40) that calculates the calorie of the object (M) in accordance with the absorbances of the light received by the light reception unit (30). In the control unit (40), the calorie of object (M) is calculated in accordance with a regression expression and the absorbances of the light received by the light reception unit (30). In this case, the regression expression is preliminarily calculated in the manner that near-infrared rays are irradiated on a calorie known sample object (M), and multiple-regression analyses are performed on second derivative spectra at the absorbances of light reflected from or transmitted though the sample object (M).

    Abstract: A remote gas measuring apparatus and method utilizes the optical absorption line characteristics to determine an amount of gas of interest as may exist in an area under study. The remote gas measuring apparatus includes a source of electromagnetic radiation (12) that can be projected toward the area in question and a light collecting arrangement (14). The light signal received is coupled to a fast light switch modulator (10) which modulates the light signal to a first frequency. A second modulating arrangement (40) modulates the light signal to a second frequency and includes a birefringent etalon device (42) having a periodic spacing equal to the periodicity of the absorption lines of the gas of interest. The second modulating means is further effective such that, when an electric field (48) is applied thereto the transmission spectra associated with the light signal is shifted between spectra which coincide with the absorption lines and spectra which fall between the absorption lines. The light signal from the etalon device is then conditioned and input to a detector configuration (56) which distinguishes between the light signal at the first frequency and the light signal at the second frequency in order to determine at least a quantity of the gas of interest.
