Example Embodiment
[0036] In order to better understand the present invention, specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0037] Such as figure 1 As shown, the in-vivo electric field measurement device based on the quantum coherence effect disclosed in this embodiment includes a semiconductor laser and its control unit, a laser control optical path, a fiber-coupled atomic gas cell electric field probe, and a photoelectric detection unit. The detection light laser and its control module emit a weak detection light with a wavelength of 780nm, which passes through the frequency control module, the polarization state control module and the power control module successively to make it become the detection light with stable frequency, horizontal linear polarization state and stable power. At the same time, the coupled optical laser and its control module emit a strong coupling light with a wavelength of 480nm. Similarly, it passes t...
