Abstract: An improved method and apparatus for use in optical testing of concentration in samples has been developed. The apparatus restricts the solid angle of illumination and the solid angle of detection to eliminate a high proportion of the scattered radiation while allowing the ballistic radiation and the snake-like radiation to be transmitted. In samples which contain multiple scattering centers, this allows less correction for variations in effective pathlength and allows easier calibration of the apparatus. The use of polarized radiation as a means of minimizing scattered radiation in the sample is also disclosed.

Abstract: A system for providing recognition of an approaching object located in a distant no-light environment includes an illumination source for transmitting light to the distant object and an imaging device for detecting the light radiation reflected from the distant object to generate an image of the distant object corresponding thereto. The system also includes an independent digital signal processor for calculating a desired optical magnification of a lens of the imaging device as a function of a distance between the imaging device and the distant object and generates a voltage corresponding thereto. The digital signal processor applies the voltage to the digital zoom circuitry of the imaging device to adjust the magnification of the lens so that the image of the distant object is held in a fixed dimension.

Abstract: For quantitative analysis of gas volumes, specifically combustion exhaust gases, by means of emission or absorption spectrometry in the ultraviolet, visible and infrared spectral range, geometrically defined and reproducibly adjustable observation planes are oriented perpendicular to the longitudinal axis of an exhaust stream. In a first series of measurements a number of m spectral measurements is performed, in such a way that the optical axis of a spectrometer is always located in the respective observation level but is shifted in a parallel direction by a first distance from one measurement to the next. In a second series of measurements n measurements are performed, in such a way that the optical axis is again located in the observation plane and is shifted in a parallel direction by a second distance from each measurement to the next. The (m+n) measurements produce two orthogonal sets of line of sights, which form a grid with (m·n) intersecting volumes. With the aid of the (m+n) measurements, each measurement yields the spectral transmission &tgr;(v), or the spectral radiation intensity I(v) which is integrated via the total gas volume in the beam of rays of the spectrometer field of view.
