Abstract: A method is suggested for obtaining information on the electromagnetic spectrum of a sample, the method comprising (a) generating a plurality of substantially identical signals, (b) determining the shape of a first number of the signals by performing a first number of scans of a first range of signal width, (c) determining the shape of a second number of the signals by performing a second number of scans of a second range of signal width, the second range being comprised by the first range and comprising a portion of the first range in which the signals have maximum absolute amplitude, (d) combining data from the first number of scans and the second number of scans so as to obtain data corresponding to the shape of the signals, and (e) performing a mathematical transformation of the combined data so as to obtain the information on the electromagnetic spectrum of the sample. According to this method, the electromagnetic spectrum - and especially an absorption spectrum for use in quantitative analysis of the sample - may be obtained faster than is possible using prior art methods.

Abstract: A multichannel imaging spectrometer for airborne geological, geophysical and environmental surveys in a moving vehicle. An optical scanner (123) employs a rotating polygon (20) allowing reduced scan optics with increased data acquisition efficiency. Multiple spectrometers (122) integrally registered allow channelization of the received signal to optimize noise performance in the range from ultraviolet through infrared. Output data is in a form for recording and real time display. A staring mode configuration provides enhanced sensitivity by using a two-dimensional detector array (320, 330) and adjustable mirror orientation. A scanning mode embodiment employs a two-dimensional detector array with time delay integration and three-dimensional storage of temporal spatial data and spectral wavelength and intensity. Thus, all channels are acquired simultaneously, resulting in perfect band-to-band registration with continuous spectral curves over the field of view.

Abstract: The object for the invention is a spectrometric, itself geometrically calibrating construction method of the light. The spectrometers using known methods are large to their size as well as expansive and they must be calibrated often. The movement required for the measuring of the spectrum in the method in accordance with the invention, with the help of which the intensities of the different wavelengths are measured, is obtained by moving the read head (5) of the diskette (6), which read head reads a certain data from the storage disk for the simultaneous control of the measuring geometry, the measuring is carried on by reading always a new spot on the disk and measuring the intensity, whereby the wished spectrum range is measured spot by spot.

Abstract: A detection system for use in an aircraft which is able to monitor atmospheric conditions ahead of the aircraft, generate an alarm signal if adverse atmospheric conditions exist ahead of the aircraft and generate information which indicates the position of the adverse conditions so the adverse conditions can be avoided. The system is able to detect the presence of volcanic ash cloud ahead of the aircraft and, if desired, can also be used to detect a high density of sulphur dioxide gas and/or clear air turbulence ahead of the aircraft. The system monitors infrared radiation received by the aircraft, generates intensity signals representative of at least one predetermined wavelength of the radiation and compares intensity signals with reference signals or intensity signals of another infrared wavelength. If the results of the comparison which indicate the adverse conditions are present, an adverse condition warning signal is generated and the device is also able to generate video display signals for producing a video display which indicates the position of the adverse conditions relative to the aircraft.

Abstract: A system and method is described for permitting the simultaneaous automated collection of data with regard to the presence of diseased cells, in particular neoplastic, dysplastic or cancerous cells, or normal cells at a given site in a section of tissue. This is accomplished according to the following steps. First, IR spectral data are collected simultaneously for each cell or pixel of the tissue. The present invention utilizes step scanning Fourier transform technology, where a moveable interferometer is used as a spectral filter. Next, these data are analyzed by identifying the cell types encountered in the sample by comparing them with reference data sets for healthy and diseased cells. Finally, a false color mapping of the distribution of different types of cells in the tissue section is presented that permits assessment of the prevalence of diseased cells.

Abstract: The spectroscopic process uses a detector in the form of a linear array of detector units made of a photoconductive semiconductor material. Radiation from a sample is limited by a slot and broken down into its spectrum; the spectrum thus obtained is used to illuminate the detector and is evaluated making use of the dependence of the conductivity of the semiconductor material on the radiation intensity. The beam path between the sample and the detector is periodically interrupted by a chopper to generate dark and bright phases. At least one measuring cycle is conducted, a measuring cycle comprising the measurement of a complete spectrum in a bright phase and a complete spectrum in an adjacent dark phase, and the measured values of a measurement quantity clearly dependent upon the conductivity of the detector elements of the detector are determined during both the dark and bright phases in one measuring period. The intensity of the radiation impinging on the detector in the bright phase is found from the comparison between the measurements obtaines in the bright phase and those found in the dark phase. The interruptions in the radiation and the measuring periods are mutually synchronised in such a way that a measuring period lies either only within a bright or only within a dark phase. The measuring period is variable and adjustable, the interruption of the beam path is regulated depending on the measuring period and a sprectrum is evaluated only once the synchronisation of the phases of the chopper with the measuring periods is ensured.
