Abstract: Method and system (300, 600, 800, 900) are disclosed for de-embedding optical component characteristics from optical device measurements. In particular, the invention uses frequency domain averaging of the RBS on both sides of an optical component to determine one or more of its optical characteristics. Where the RBS has a slope (e.g., as in the case of a lossy fiber), a frequency domain least square fit can be used to determine the optical component characteristics. In addition, the invention uses a reference DUT (604) to correct for variations in the frequency response of a photoreceiver (332). A reference interferometer (808) is used in the invention to correct for sweep non-linearity of the TLS (322). The optical component characteristics are then de-embedded from optical device measurements to provide a more precise analysis of the optical device.

Abstract: The invention describes systems and methods to obtain and present imaging data in absolute units. The systems and methods convert relative image data produced by a camera to absolute light intensity data using a compensation factor. The compensation factor accommodates for hardware and specific imaging conditions in the imaging system that variably affect camera output. The present invention determines the compensation factor based on assessing the output of the camera against a known light source for a specific set of imaging conditions in the imaging system. The compensation factor is then stored in memory corresponding to the specific set of imaging conditions. Upon subsequent imaging with the set of imaging conditions, the corresponding compensation factor is called from memory and applied to the camera output. A compensation factor may be determined and stored for each hardware state and imaging condition available to the imaging system.

Abstract: Bei einem Messverfahren zur Bestimmung der optischen Transmission oder Reflexion sowie davon abgeleiteter Messgrößen, wobei die Messstrahlung ausgehend von einer modulierten Strahlungsquelle nach der Wechselwirkung mit einem Messobjekt, vorzugsweise in einer Messküvette, von einem Detektor erfasst, in ein elektrisches Signal umgewandelt, frequenzselektiv verstärkt und einer Auswerteeinrichtung zugeführt wird, ist zur Verbesserung des Signal/Rauschabstandes ein Halbleiterlaser oder eine LED vorgesehen, dessen bzw. deren Leuchtstärke sinusförmig moduliert wird. Die sinusförmige Modulation der Leuchtstärke kann durch Stromeinprägung und/oder Modulation der Versorgungsspannung der Lichtquelle oder durch eine elektrooptische Modulation der Messstrahlung erfolgen.

Abstract: A light source (12) emits radiation which is maintained at a desired intensity by use of a photodetector which views the radiation and has a fixed relationship between incident radiation and output photodetector (18) current. Intensity of the radiation is established by varying electric current applied to the source, via a feedback loop (42, 24, 22, 34), to attain a reference value of the photodetector current, the photodetector current being representative of the desired value of radiation intensity. This procedure may be performed first in an air environment with a specific optical assembly of source and photodetector to establish the reference value of photodetector current for a desired value of radiation intensity. Thereupon, the optical system may be operated in a vacuum environment, and a monitoring of the photodetector current establishes the desired value of radiation intensity. Alternatively, the source is operated at a fixed value of excitation current, and an iris (44) or other radiation attenuator is operated to produce the reference value of photodetector current.

Abstract: System using uses a single channel light meter to measure the actual red, green and blue light output response curves of a CRT monitor to the range of possible input monitor code values for each color. A computer is used to transform a desired corresponding tone scale through the corresponding response curve to obtain a look-up table or video shaper that calibrates the monitor to the desired corresponding tone scale. The transformation includes obtaining a tone scale intensity value for each possible input value and searching the actual response values for a closest match. The input monitor code value used to obtain the actual response matching intensity for the possible input value is the calibrated value displayed by the monitor when an image includes the possible input value. The system is used throughout the life of the monitor to bring the monitor back to calibration as it changes.
