Abstract: Optical systems that provide for simultaneous images and spectra from an object, such as a tissue sample, an industrial object such as a computer chip, or any other object that can be viewed with an optical system such as a microscope, endoscope, telescope or camera. In some embodiments, the systems provide multiple images corresponding to various desired wavelength ranges within an original image of the object, as well as, if desired, directional pointer(s) that can provide both an identification of the precise location from which a spectrum is being obtained, as well as enhancing the ability to point the device.

Two colors are separately imaged by the detector in two imaging regions. The imaging system for each color includes a color filter positioned between the scene and the respective region of the detector, an optical train that forcuses filtered color scene energy, and an optical fiber bundle having an input end that receives the respective color scene energy from the optical train and an output end that directs the color scene energy onto the respective region of the detector using a nonlinear mapping. The optical fiber bundle is formed of a plurality of optical fibers wherein each of the optical fibers has an input shape and size at its input end and an output shape and size at its output end.

Abstract: Raman spectrometer for analyzing the chemical composition of sample streams using an external cavity laser light source is disclosed. The laser (12) provides an effective light source useful in continuously analyzing a sample stream containing petroleum products, aqueous or biological fluids, or solid slurries. The light is introduced into a bundle of optical fibers (16) connected to a Raman sample cell (20). The Raman sample cell (20) is configured to allow continuous sample flow therethrough. Scattered light from the sample cell (20) preferably exits the optical fibers (18) as a linear optical signal. A Raman spectrometer (36) passes the optical signal through an excitation wavelength filter (40), an optical slit (42), and an aberration correction device (54) before transmitting the optical signal to a charge coupled device array (44) which converts the optical signal into an electronic signal. The electronic signal is analyzed and converted by computer (46) into a representation of the chemical analysis of the sample stream.

Abstract: An optical system having a first order spectral range that is usable in an optical spectrum analyzer receives an broadband optical test signal and a optical calibration signal and couples the optical signals via two optically isolated paths to separate optical detectors. First and second pairs of optical fibers, with each pair having an input fiber and an output fiber, are positioned in a focal plane of a collimating optic that has an optical axis. The fiber pairs are symmetrically positioned on either side of the optical axis with the input fibers positioned on one side of the optical axis and the output fibers positioned on the opposite side of the optical axis. The input fibers receive the optical test signal and the optical calibration signal. The output optical fibers are coupled to first and second optical detectors. An optical calibration source generates second order or greater spectral lines that fall within the first order spectral range of the optical system. A diffraction grating receives the optical test signal and the optical calibration signal from the collimating optic and separates the first order spectral components of the broadband optical test signal and passes the second order or greater spectral lines of the optical calibration signal. The first optical detector that is responsive to the first order spectral components of the optical test signal receives the optical test signal from the collimating optic and converts the optical test signal to an electrical signal. A second optical detector that is responsive to the second order or greater spectral lines of the optical calibration signal concurrently receives the optical calibration signal from the collimating optic and converts the calibrations signal to an electrical signal.

Abstract: A spectrophotometric instrument including light signal sources, a detector, a processor/controller, a probe and a calibration device. The light signal sources have measurement light wavelengths and a calibration detection wavelength. The probe has one or more send fibers coupled to the measurement and calibration light signal sources for transmitting the light signals into tissue, and one or more receive fibers for receiving light including the measurement light signals and the calibration light signal. The calibration device is adapted to receive the probe and has an optical filter for transmitting the measurement light signals but not the calibration light signal. The detector is coupled to the receive fibers to generate electrical signals representative of the light received at the receive fibers. The processor/controller is coupled to the detector and initiates a calibration procedure when the calibration light signal is not detected.

Abstract: A spectrum analyzer providing an integrated calibration function and for providing that calibration function automatically. The injection of light to be analyzed through a central aperture (14) of a scanning grating (12) onto a focusing reflector (16) provides in combination four traversals of the space therebetween. The spectrometer thus is used to separate wavelength information spacially and receive it back at the same or adjacent aperture(s) (14) to be analyzed by a processing system (50) to establish the spectra for the incident light. The light is typically injected from and received back into optical fibers (42, 46) or other light carrying elements. Calibration light is also applied through the same or adjacent apertures (14) in the grating (12) from a known source and spectra such as Argon to use as a calibration reference by detecting the known spectra peaks and correlating it to grating scan angle. The same structure is also used as a telecommunications channel router.
