    Abstract: An acousto-optical tunable filter is disclosed. The filter includes a medium having one or more indices of refractions alterable by the application of acoustic waves to the medium. The filter also includes an acoustic transducer coupled to the medium to generate the acoustic waves Altering the frequency of the acoustic wave selects among the different wavelengths in the incident light ray. The device also includes an optical mirror for reflecting a wave diffracted by the medium back to the medium so that it can again be diffracted. The first diffracted wave has its frequency shifted in one direction by the frequency of the acoustic wave while the second diffracted wave has its frequency shifted in the opposite direction, thereby compensating for the first shift. The result is an output ray with little or no frequency shift.

    Abstract: A system and method for detecting dynamic changes that occur in a sample between a first time interval and a second time interval using a series of at least first and second sequential chemical images of the sample. During the first time interval: (i) the sample is illuminated with a plurality of photons to thereby produce photons scattered or emitted by the sample; (ii) a two-dimensional array of detection elements is used to simultaneously detect scattered or emitted photons in a first predetermined wavelength band from different locations on or within the sample; and (iii) the two-dimensional array of detection elements is thereafter used one or more further times to simultaneously detect scattered or emitted photons in one or more further predetermined wavelength band(s) from different locations on or within the sample. The outputs of the two-dimensional array of detection elements during the first time interval are then combined to generate the first chemical image of the sample. The process is repeated during the second time interval to generate the second chemical image of the sample. Dynamic changes occurring in the sample between the first time interval and the second time interval are detected based on one or more differences between the first and second chemical images.

    Abstract: A spectrometer for infrared reflectance measurements of samples for identification of the sample materials is built into a steering wheel assembly. The spectrometer includes a window and optics on a bench adjacent the window, so that the optics will be aligned with the sample when the device is placed in optical alignment with or directly against the sample. The optics include a broad-band IR light source (ordinary lamp) shining onto an acousto-optic tunable filter (AOTF), which passes narrow-band IR light with a swept frequency; a lens focusing the IR through the window onto the sample; and a reflectance detector aligned with the window of the spectrometer to pick up reflected light. A computer, which may be mounted in the spectrometer, compares the detected reflectance spectrum with stored sample data spectra, and identifies the material or the components of the material and their proportions. When a control substance is detected an alarm signal is produced.

    Abstract: In an optical spectrum analyzer comprising a spectrograph and a photodevice array, and an optical spectrum detecting method, a wavelength deviation, from an assigned wavelength, of a light detected by a photodevice array which detects a wavelength of a diffraction light or a non-diffraction light from an acoustooptic device, is detected and a feedback control to a diffraction angle of the acoustooptic device is performed. Also, without using a feedback control, an exit light and a diffraction light from the acoustooptic device are respectively received by two photodevice arrays and the photodevices are arranged in order to mutually compensate gaps between the photodevices, whereby a center of each photodevice is similarly made coincide with a peak of an optical beam to be received.
