    摘要: Gas within a ventilation circuit (12) is analyzed by a spectrometer included in gas measurement module (16) that is inserted into the respiratory circuit. The gas measurement module includes an infrared source and a movable filter member comprising at least two filter elements. The optical path length of the spectrometer is reduced. This includes removing optical components configured to collimate or focus electromagnetic radiation within the spectrometer. However, path length of the spectrometer is reduced to the point that other enhancements associated with path length reduction outweigh losses to precision and/or accuracy caused by beam expansion in the spectrometer.

    摘要: An airway adapter that comprises a housing and a pressure transducer. The housing comprises a flow path having a first end and a second end, a first pressure port that communicates with the flow path, and a second pressure port that communicates with the flow path. The first pressure port is spaced apart from the second pressure port. The flow restriction is disposed in the flow path between the first and second pressure ports that creates a pressure differential therebetween. The pressure transducer generates a signal that reflects the differential pressure created by the flow restriction between the first and second pressure ports, wherein the pressure transducer comprises an optical interferometer.

    摘要: A compact optical memory is disclosed in which data are stored in an optical data layer capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data are illuminated by controllable light sources and an array of multi-surface diffractive imaging lenslets cause a data image to be projected onto an array of light sensors by multiple reflections of, hence folding the image rays, by surfaces that both reflect and optically modify the light rays to redirect them onto the sensor array. Data are organized into an annular array of patches (called pages). By selective illumination of each data page, one of the lenslets images the selected data page onto a central image plane where the sensor array is located. Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting information in the form of electrical data signals.

    摘要: An optical memory is disclosed in which data is stored in an optical data layer capable of selectively altering light such as by changeable transmissivity or polarization. The data is illuminated by controllable light sources and an array of multi-surface imaging lenslets project the image onto a common array of light sensors. Data is organized into a plurality of regions or patches (called pages) in which each page contains a field of data spots that encode multiple states or levels of data by the amount of transmissivity or polarization of that spot. By selective illumination of each data page, one of the lenslets images the selected data page onto the light sensors. Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting the multiple levels per spot in the form of electrical data signals that are A/D converted to digital. A special sensor array uses charge coupled devices (CCDs) that provide multiple storage buckets or levels for each photo sensor element to store and output reference level data along with signal data to quantify and normalize the sensor elements. By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer, correspondingly different data spot patterns are imaged by the corresponding lenslets onto the common sensor array, thereby enabling many stored data pages to be retrieved by multiplexing at electro-optical speed.

    摘要: A detector unit which is capable of outputting electrical signals proportional in magnitude to the intensity of that energy in a beam thereof which lies in two different wavelength bands. A beam splitter directs energy in those bands from the entire compass of the beam to a data detector and a reference detector, and bandpass filters and optical traps in front of those detectors ensure that only energy in the selected bands and from the beam reach them. The detectors are mounted in precisely aligned relationship with each other and the beam splitter on, and are electrically isolated from, a monolithic, conductive, isothermal support which allows them to be maintained at the same, selected temperature by a system including data and reference detector heaters and a temperature responsive controller.

    摘要: A transducer for nondispersive infrared gas analysis has heaters for the data and reference detectors to maintain the detectors at a selected temperature. A heater is also provided to heat the casing of an airway adapter associated with the transducer to a temperature high enough to keep condensation from forming. The detector unit is surrounded and electrostatically shielded by a boxlike component with barndoor extensions which are closed to shield the installed detector unit at that end of the shield through which the detector unit is installed. The detector unit, electrostatic shield, and a circuit board which carries power supply and preamplifier circuits are installed in the transducer housing which has separate end closures sealed thereto with a through fastener and internal guides for locating the shielded detector unit in the housing.

    摘要: A first or ranging light beam which functions as a carrier is amplitude modulated with a first radio frequency f.sub.1 ; a second amplitude modulated light beam source functions as a local signal at a frequency f.sub.2 for a heterodyne conversion of the first frequency f.sub.1 ; and an electro-optical detector receives both modulated light beams and functions as a mixer. Electro-optical heterodyning of the modulations on the ranging and local source light beams is accomplished by mixing RF modulations on the first light beam with RF modulation on the second light beam in the electro-optical detector to thereby produce a resultant, relatively lower difference frequency (f.sub.1 -f.sub.2) that is more readily processed by available electronic components. Distance measurement is represented by a phase shift of the relative low frequency difference of the heterodyned modulation signals when compared to a reference, unshifted phase of the same frequency.

    摘要: An optical system is provided implementing a field correction apparatus. The system includes a rotating support driven by a motor. A plurality of focussing lenses are circumferentially spaced about the axis of rotation of the support. As the support rotates, each focussing lens successively passes over a record medium in an arcuate path. The support is also provided with a pyramidal distributing mirror having a number of reflecting surfaces. Each reflecting surface of the disturbing mirror is associated with one of the focussing lenses. The pyramidal distributing mirror is mounted on the center of the support and receives an optical beam on one of its reflecting surfaces. The optical beam is conveyed to the reflecting surface associated with the focussing lens passing over the record medium in a plane that includes the axis of rotation of the support. The optical beam is also directed to the reflecting surface at an angle to the axis of rotation. A field correction lens receives the reflected beam from the reflecting surface and refracts the optical beam so that the optical beam after emerging from the field correction lens follows a path substantially coincident with a radial line extending from the axis of rotation of the support to the optical axis of the focussing lens during the entire pass of the focussing lens over the record medium. A method of aligning an optical beam to become incident on the optical axis of a focussing lens is also provided.
