A light intensity modulator includes an input optical fiber; an output optical fiber; an optical arrangement having a lens, where the optical arrangement is configured to receive light from the input optical fiber, pass the light through the lens, and direct the light to the output optical fiber; and a piezoelectric device coupled to the lens, where the piezoelectric device is configured for moving the lens to alter overlap of the output optical fiber and the light directed to the output optical fiber to modulate intensity of light in the output optical fiber.

A magnetic field measurement system includes a magnetometer having at least one vapor cell, at least one light source to direct at least two light beams through the vapor cell(s), and at least one detector; at least one magnetic field generator to modify an external magnetic field experienced by the vapor cell(s); and at least one processor configured for: applying a first modulation pattern, b(t), to the magnetic field generator(s) to modulate a magnetic field at the vapor cell(s), where b(t)=[ccos(&#x3c9;t)+ssin(&#x3c9;t), ccos(&#x3c9;t)+ssin(&#x3c9;t), ccos(&#x3c9;t)+ssin(&#x3c9;t)], where c, s, c, s, c, and sare amplitudes and &#x3c9; is a frequency; directing the light source(s) to direct the light beams through the vapor cell(s); receiving signals from the detector(s); and determining three orthogonal components of the external magnetic field using the received signals. Multi-frequency modulation patterns can alternatively be used.
