    摘要： A device detects multi-spectral imaging by using line scan elements. The device may include an illumination module and a detection module to detect light scattered from an object illuminated by the illumination module. The device may also include an array of light sources to produce light at a plurality of different wavelengths, and create a uniform line of illumination with each of the different wavelengths. The light detection may be applied to authenticate and validate documents, such as bank notes moving along a document conveyer.

    摘要： A method and apparatus for spread spectrum distance and for spread spectrum velocity profile measurement is provided where the short pulse of traditional ultrasonic and radar level gauges is replaced by low peak power direct sequence spread spectrum (DSSS) modulated energy. An echo sequence subtraction process is provided that increases the signal to noise ratio of each echo sequence thus increasing the dynamic range of the system. In addition to providing a higher signal to noise ratio (SNR), better precision and accuracy in ranging Doppler applications and the ability to use lower peak power transmissions, the system is more immune to interference from the environment and allows for less expensive and less bulky ultrasonic transducers.

    摘要： Disclosed is a functional NIRS imaging system including an elastomeric cap, a set of transmit optical fibers and a set of receive optical fibers terminating on the inside surface of the elastomeric cap. A pair of light sources combines to produce a collimated light beam at two wavelengths. An optical modulation system, converts the light beam into a plurality of probe light beams, modulates the plurality of probe light beams with a set of pseudo-orthogonal codes and directs each probe light beam into a transmit fiber. An optical detection system accepts scattered photons from subcutaneous tissue underneath the elastomeric cap as a plurality of collected light beams and converts them into a time series of electronic images, stores the electronic images into the memory and processes the electronic images using the pseudo-orthogonal codes. The system displays the resulting image on a display as a hemoglobin oxygen saturation map.
