The utility model relates to a realize helium optical pump magnetometer probe of scalar vector simultaneous measurement. Include: magnetic sensor and coil total, magnetic sensor includes dumbbell shape helium lamp, concavees lens, inclined to one side vibration -damping sheet, lambda / 4, helium absorption chamber, convex lens that set gradually in the probe casing and the light -sensitive device who is located the convex lens rear on same straight line, the coil total is including the RF coil who is located helium absorption chamber, through helmholtz coil production radio frequency field, make the atom take place to go the orientation effect, the coil total is still including using helium absorption chamber as optimal power flow, three mutually perpendicular's first coil, second coil and tertiary winding. The utility model provides a measurement to the vector sum scalar in magnetic field has been realized through three orthogonal coil to helium optical pump magnetometer probe, has changed the mode that traditional helium optical pump magnetometer can only the measurement probe volume, this application that will extend helium optical pump magnetometer.
