Abstract: An interferometric spectrum analyzer employs a pair of Bragg cells arranged in an optically cascaded configuration such that both the signal beam and the reference beam travel along a common optical path. The beam-modifying properties of the Bragg cells are such that within a prescribed bandwidth of operation, the deflection properties of the respective cells are frequency complementary, namely different frequencies applied to the respective cells deflect the beam passing therethrough along the same optical path, to produce a beat frequency at the Fourier transform plane. In accordance with a first embodiment, complementary deflection action is achieved by using Bragg cells having respectively different acoustic velocites. In a second embodiment, each Bragg cell has the same acoustic velocity. The deflection/frequency complementary effect is obtained by the use of a birefringent material prism interposed between the Bragg cells, which produces angular deviation that depends upon the polarization and the direction of propagation of light passing through the prism.

Abstract: For detecting specific gases in an automobile exhaust selected lines of the exhaust gas absorption spectrum and reference bands of the spectrum close to the lines are chopped by a mask at the spectral plane so that the light flux from the lines and bands are transmitted at different times. The flux of the lines and bands are also encoded by the chopping mask or a successive encoding mask and applied to a single photodetector which produces a series of electrical values representing the flux of the selected spectral lines.

Abstract: A device images radiation from a scene. A detector is sensitive to the radiation in a first wavelength band. A lens forms an image of the scene on the detector. A filtering arrangement includes two sets of radiation absorbing molecules. A control unit switches the filtering arrangement between two states, in the first state, all of the radiation in the first wavelength band is transmitted to the detector, in the second state, the radiation in a second wavelength band within the first wavelength band is absorbed by the radiation absorbing molecules. The control unit synchronizes the switching of the filtering arrangement with the detector. Each pixel of the image formed on the detector includes two signals. The first signal includes information from the scene radiation in the first wavelength band. The second signal excludes information from the scene radiation absorbed by the filtering arrangement in the second wavelength band.

Abstract: An optical analysis system and process are disclosed. The optical analysis system includes one or more optical filter mechanisms disposed to receive light from a light source and a detector mechanism configured for operative communication with the one or more optical filter mechanisms, the operative communication permitting measurement of properties of filtered light, filtered by the one or more optical filter mechanisms followed by optical filtering by the mosaic optical filter mechanism from the light received. The one or more optical filter mechanisms are configured so that the magnitude of the properties measured by the detector mechanism is proportional to information carried by the filtered light. The process uses the optical analysis system.

Abstract: Technologies are described for providing optical analysis systems using an integrated computational element that has a surface patterned to selectively reflect or transmit different wavelengths by differing amounts across a spectrum of wavelengths. In one aspect, a measurement tool contains an optical element including a layer of material patterned so that the optical element selectively transmits or reflects, during operation of the measurement tool, light in at least a portion of a wavelength range by differing amounts, the differing amounts being related to a property of a sample. The wavelength range can include wavelengths in a range from about 0.2µm to about 100µm. Additionally, the sample can include wellbore fluids and the property of the sample is a property of the wellbore fluids.
