Abstract: Weak signals scattered from analytes at multiple wavelengths can be summed to illuminate either a single detector or a multiplicity of detectors, offering the possibility of concentrating the spectral energy on a smaller total detector area. In addition, a method is disclosed whereby a calibration of the resulting signal for a given analyte can be obtained by means of measuring the quantity of water in the sample volume and by means of measuring the salinity of the fluid in the sample volume.

Abstract: A two color radiation detector. A dispersive lens with a spectrally selective central obscuration focuses a first radiation band on a central location on focal plane array. The dispersive lens also focuses an annulus of out of focus radiation of a second radiation band concentric with the central location on the focal plane array. For point target detection the dispersive lens transmits plume band and guard band radiation to the staring focal plane array sensor. The staring focal plane array is located at the focal point of the plume band radiation. A spatial filter detects target signatures using information from the plume band and guard band radiation.

Abstract: In a spectrophotometer for measuring the concentration of a specific substance, a pulsating (modulated) source of radiation gives rise to an alternating current component, a direct current component and a dark signal component in a measurement signal. The response time for changes in the concentration of the specific substance is reduced while the measurement signal's signal-to-noise ratio is simultaneously improved when the pulsation frequency is from 50 to 1000 Hz, and the direct current component in the measurement signal is filtered out for normalization by a reference signal in a signal analyzer so the concentration of the specific substance can be calculated.

Abstract: A plurality of test tubes containing specimens are passed successively through a predetermined position. Two monochromatic beams are transmitted alternately along a single path through said predetermined position and through each of the test tubes passing through said predetermined position. The characteristics of the two beams are such that one of them is capable of being absorbed by the specimen and the other substantially incapable of being absorbed. Thus it is possible to obtain an electric signal representing the ratio or difference between electric signals corresponding to said two monochromatic beams.

Abstract: A beam of light passes through a sample and the transmitted light beam is detected by a detector. The light beam to be detected by the detector is a monochromatic light beam obtained by a dispersing means and the wavelength of the monochromatic light beam is continuously varied by a wavelength scanner. A transparent plate is obliquely positioned in the path of the monochromatic light beam so that the detector delivers an electrical signal representative of the absorption when the transparent plate lies in the path of the light beam and another electrical signal representative of the absorption when the transparent plate does not lie in the path of the light beam. A ratio detector or a difference detector compares these electrical signals with each other or subtracts one of these electrical signals from the other thereby obtaining a differential spectrum.

Abstract: A modulation method comprising steps of: a) generating a first signal having a first train of short pulses having a first frequency, and a second signal having a second train of short pulses having a second frequency, wherein each of the signals are associated with a negative or positive sign; b) maintaining a narrow frequency difference between the frequencies; c) imposing chirped modulation on each of the signals to achieve a desired spectral resolution, such that each signal is associated with a chirp having a first sign and a second sign; and d) switching between the signs for each signal over a frequency range, and detecting for each frequency of said frequency range, a spectral response resulting from a transfer of said modulation between the signals wherein the chirp sign of each of the signals is different, thereby obtaining hyperspectral data of said spectral response over said frequency range.
