Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference. Thus, these measurements can be performed substantially simultaneously with minimal interference from each other. The pulse oximetry measurement system correlates the measured light intensities using pseudo-random noise generation and phase division multiplexing, and computes the measured and correlated peak- to-peak detected light amplitudes to obtain a ratio between these light amplitudes for determining oxygen saturation in the blood, and may also be used for heart rate monitoring.

Abstract: The averaged pulse energy (J) of a Pulsed Type Laser Source can be measured by several types of commercial laser energy meters, such as pyroelectric detector or thermopile sensor, the spectral responsivity and the time/frequency related response properties of which are compatible with those of the Pulsed Type Laser Source. These Commercial Laser Energy Meters, regardless of sensor/detector type, should be calibrated against the working standards calibrated in a national (or an international) traceability chain relying on primary standards on the highest level having the lowest uncertainty in realizations of the fundamental SI units. FCIS based-LEMCS designed in this invention accomplishes both of the above proficiencies of measuring the averaged pulse energy of the Pulsed Type Laser Source and calibrating the Commercial Laser Energy Meters, which are traceably to primary level standards. FCIS based-LEMCS contains an integrating sphere having a novel port and an interior design and a series of mechanical choppers having separate Duty Cycles, each of which is rotated by an electrical motor in FCIS based-LEMCS, used for generating a chopped type laser, called as Chopped Type Laser Source, in order to provide the reference and averaged pulse energy for traceable calibration of Commercial Laser Energy Meters. With this invention, in addition to generating the reference and averaged pulse energy to be used during the calibration of Commercial Laser Energy Meters to be performed by means of FCIS based-LEMCS, the peak pulse energies of the Pulsed Type Laser Source and the Chopped Type Laser Source, which is a strict part of FCIS based-LEMS and which is used for producing the reference averaged pulse energy in the calibration of Commercial Laser Energy Meters, are also measured by FCIS based-LEMCS, traceable to Electrical Substitution Cryogenic Radiometer (ESCR) in primary optical watt scale (W), to 133 Cs (or 87 Rb) Atomic Frequency Standard in time scale t (s), and to direct current unit (A) realized with Quantum Hall - primary resistance standard (ohm) and DC Josephson primary voltage standard (V). With this configuration presented as a preferred embodiment, the averaged pulse energy measurements are performed and achieved for a range extending from 16.5 p J to 100 mJ.
