An embodiment of the invention relates to a device comprising an array of optical magnetometers. The magnetometers comprise se a light source, a container having a chamber filled with an atomic vapor, and a photo detector capable of detecting optical properties of the atomic vapor. The substrate and the array of the magnetometers are designed such that the magnetometers are able to detect weak magnetic fields. Also, the magnetometers are capable of detecting distinct portions of a magnetic field, such as a non-uniform magnetic field, using a single or a plurality of the magnetometers in the array simultaneously. Other embodiment of the invention include methods of making a device that comprises an array of magnetometers and methods of detecting a magnetic field using the device. The device and method can be used in medical diagnostics, such as detecting biomagnetic activities of the human's heart and brain.
