Abstract

Magnetic encephalography is currently the most informative method of functional study of the brain, since, unlike other methods, it allows one to localise deep sources of biosignals and perform three-dimensional mapping of neuronal activity. The main factors hindering the development and spread of this method are the complexity and high cost of diagnostic tools, as well as the rigidity of the requirements they impose on the spatial and temporal uniformity of the magnetic field. The prospects for desinging a device capable of largely overcoming these limitations are considered. A review of studies aimed at developing an optical sensor applicable to magnetic encephalography is presented. The all-optical single-beam nonzero-field sensor proposed by the authors earlier is separately considered.
用于新一代神经诊断系统的量子光磁场传感器
脑磁图是目前信息量最大的脑功能研究方法,因为与其他方法不同,它允许人们定位生物信号的深层来源,并对神经元活动进行三维映射。阻碍该方法发展和推广的主要因素是诊断工具的复杂性和高成本,以及它们对磁场时空均匀性的刚性要求。展望了设计一种能够在很大程度上克服这些限制的装置的前景。本文对脑磁成像光学传感器的研究进展进行了综述。本文对前人提出的全光单光束非零场传感器进行了单独讨论。
