Abstract: A process for analyzing a spectral signal generated by a birefringent element and transmitted to an array. An output spectral signal emanating from the array is converted from an analog to a digital signal to establish a reference wave form which has a dominant frequency after the birefringent element is exposed to a known temperature. Thereafter, a current wave form is generated from the output spectral signal emanating from the array. A phase and frequency relationship is obtained by cross correlating the current wave form and the reference wave form. The dominant frequency for the phase and frequency relationship is obtained by Fast Fourier Transformation. Thereafter, the dominant frequency for the phase and frequency relationship of the current wave form is compared with the dominant frequency for the reference wave form to determine a temperature range. The temperature range and phase and dominant frequency for the current wave form are matched with a reference schedule stored in the memory of a digital signal processor to predict the current temperature experienced by the birefringent element. This predicted temperature is displayed on a screen to inform an operator of the current operational conditions experienced by the birefringent element.

Abstract: A light off detecting arrangement for sensing the presence of a flame in a region such as the afterburner of a turbine engine is disclosed. An optical focusing device such as a lens or mirror is located near a quartz window adjacent the afterburner for concentrating electromagnetic radiation emanating from the region. An optical (fiber optic) pathway receives the concentrated electromagnetic radiation from the optical focusing device and conveys that radiation thru the optic filters to an opto-electrical converter for converting incident electromagnetic radiation to electrical signals. A frequency selective optical device such as an infrared filter is interposed between the optical focusing device and the opto-electrical converter for insuring that a preselected portion only of the electromagnetic radiation emanating from the region is converted to electrical signals. The electrical signals are compared to a predetermined threshold value and a fault flame present indication is issued if the comparison indicates sufficient radiation in the preselected portion indicative of the presence of a flame, and a second no flame indication is issued otherwise.

Abstract: An electro-optic speed sensor for sensing the speed of rotation of a rotating sending unit which includes an optical switch transducer for sensing disturbances in a magnetic field caused by the passage of a rotating magnetic sending wheel on the rotating member. The optical switch transducer uses a Faraday material and provides its signal by rotating the polarity of polarized light from a first source of light having a first bandwidth while allowing a second source of light having a second bandwidth to pass through unaffected. The first and second sources of light are thereafter, reflected within the transducer. The disturbances in the magnetic field generate an optical signal resulting from changes in the Faraday rotation. A photodetector receives the light from the first source to develop an operational signal corresponding to the speed of rotation of the rotating member and light from the second source to check on the continuity of the sensor system.

Abstract: A sensor for use in an optical temperature detector system having a birefringent element made of a single crystal metal oxide plate. A broad band light spectrum is transmitted through a first linear polarizing element to create a linearly polarized wave. The linearly polarized wave on passing through the single crystal metal oxide plate decomposes into first and second orthogonally polarized waves. Propagation of the linearly polarized wave through the birefringent single crystal metal oxide plate introduces a temperature dependent phase shift between the two waves. Thereafter, a second linear polarizer combines the first and second orthogonally polarized waves to create a modulated light spectrum having a fringe pattern, the fringe pattern being a function of the current temperature experienced by said birefringent element. A fiber optic cable connected to the second linear polarizing element carries the modulated light spectrum to an opto-electronic interface where the fringe pattern is extracted and a computer compatible signal is generated for a CPU to accurately indicate current environmental temperature conditions up to 1000.degree. C. experienced by the single crystal plate crystal in the birefringent element.

Abstract: A wideband optical micro-spectrometer system for detecting the intensity of light as a function of wavelength. The device employs multiple optical micro-spectrometers generating adjacent spectra mounted onto a single photodetector array and digital processing techniques to generate a continuous wide spectrum from the narrower spectrums generated by the optical micro-spectrometers. Optical micro-spectrometers generating non-adjacent spectra could also be employed to produce spectral data for predetermined non-adjacent spectral ranges. System reliability is improved and maintenance reduced with the use of pre-aligned optical micro-spectrometers. Thereby, a device is created which has the spectral range of larger spectrometers having a much reduced physical size, increased system reliability and reduced maintenance requirements.
