Patent ID: 10928374

Abstract:
A measurement system comprises a pulsed, near-infrared array of laser diodes, the laser diode array comprising Bragg reflectors, and wherein laser diode light is configured to penetrate tissue comprising skin. A detection system comprising a camera is synchronized to the laser diodes, and the camera is configured to receive some of the laser diode light reflected from the tissue. The detection system is configured to non-invasively measure blood within the skin, the detection system is configured to measure absorption of hemoglobin in the wavelength range between 700 and 1300 nanometers, and the processor is configured to compare the absorption of hemoglobin between different spatial locations of tissue and over a period of time. Physiological parameters are measured by the system. The measurement system is configured to use artificial intelligence in making decisions, and the system is further configured to use regression signal processing, multivariate data analysis, or component analysis techniques.
