Dual channel self-oscillating optical magnetometer
We report on a two-channel magnetometer based on non-linear magneto optical rotation in Cs buffered glass cell. The Cs atoms are optically pumped and probed by free running diode lasers tuned to the D2 line. A wide frequency modulation of the pump laser is used to produce both synchronous Zeeman optical pumping and hyperfine repumping. The magnetometer works in an unshielded environment and spu...
متن کاملMulti-channel atomic magnetometer for magnetoencephalography: A configuration study
Atomic magnetometers are emerging as an alternative to SQUID magnetometers for detection of biological magnetic fields. They have been used to measure both the magnetocardiography (MCG) and magnetoencephalography (MEG) signals. One of the virtues of the atomic magnetometers is their ability to operate as a multi-channel detector while using many common elements. Here we study two configurations...
متن کاملA 19-Channel d.c. SQUID Magnetometer System for Brain Research
A lPchanne1 d.c. SQUID magnetometer system for neuromagnetic investigations is under constuction. The first-order gradiometers for sensing the signal are placed in a hexagonal configuration. D.c. SQUIDS based on niobium/aluminium technology have been developed, leading to a field sensitivity of about 5 fT/JHz. SQUID read-out is realized with a resonant transformer circuit at 100 kI-Iz. The mult...
متن کاملMulti-channel UART Controller with Programmable Modes
In the recent years the development in communication systems requires the data transmission to be performed faster and faster. To meet this demand the paper presents a high speed multi channel UART controller based on FIFO (First In First Out) technique . An Asynchronous FIFO is designed with dual port ram array and with read and right pointers. The structure of controller is designed with UART...
