摘要： The present invention relates to a method for measuring blood flow in living tissue and a device for performing the method. The device comprises a laser and a photo sensor. The laser is arranged to illuminate (10) the tissue in such a way that a portion of the light beam, scattered by the tissue, re-enters the laser in order to obtain a self-mixing effect. The resulting light, that is registered (11) as an electric signal by the photo sensor, contains a speckle pattern that is depending on blood cell movement in the tissue. A Fourier transform is applied (12) to this signal and an exponential fit is applied (13) to the resulting frequency domain spectrum. Thereby parameters corresponding to the amount of blood cells and the average velocity of these cells may be obtained.

摘要： A relative movement sensor for measuring movement of an object (15) and the sensor relative to each other, the sensor comprising a plurality of lasers (3,5) for generating respective measuring beams and illuminating the object (15) therewith, and a plurality of respective photodiodes (4,6) for measuring changes in operation of each laser cavity caused by reflected measuring beam radiation re-entering the respective laser cavity and the optical wave in the laser cavity. The plurality of lasers (3,5) are operated in a time-multiplexed manner such that only a subset (i.e. one or more) of the lasers is operated at any one time, the remaining lasers being idle. This reduces peak power dissipation and prevents erroneous interference caused by measuring beam radiation from one laser entering the cavity of another laser.
摘要翻译：一种用于测量物体（15）和传感器相对于彼此的运动的相对运动传感器，所述传感器包括用于产生相应测量光束并且与其对照的物体（15）的多个激光器（3,5），以及多个用于测量由反射的测量光束辐射重新进入相应的激光腔和激光腔中的光波引起的每个激光腔的操作变化的各个光电二极管（4,6）。多个激光器（3,5）以时间复用的方式操作，使得只有一个激光器的子集（即一个或多个）在任何一个时间被操作，剩余的激光器是空闲的。这降低了峰值功率消耗，并防止了通过测量来自一个激光器进入另一激光器的腔体的光束辐射引起的错误干扰。

摘要： A method is proposed for investigation of or ascertaining pulse or heartbeat. The method first comprises directing illuminating radiation to illuminate a body part such as a finger. The illuminating radiation is of a wavelength or wavelength band substantially in the blue light region of the light spectrum. Then, an optical speckle pattern of the illuminated body part resulting from the illumination of the body part is obtained and imaged. The optical speckle pattern is representative of the heartbeat and by correlation of frames extracted from the speckle pattern, the pulse or beat extent of the body part may be ascertained.

摘要： The present invention relates to a method and a device for verifying identity of an individual by employing biometric data derived from a physical feature of the individual. A basic idea of the invention is that, rather than determining peak locations in cyclic signals such as ECG or PPG signals when using these signals as a representation of biometric data for verifying identity of an individual, shape or morphology of the signals is considered.
