Electromagnetically induced grating-based electric field detection system and method

An electromagnetically induced grating-based electric field detection system comprising:

• a vapor cell;
• an irradiation light source configured to irradiate irradiation light to be incident on one end of the vapor cell;
• a combined light source configured to irradiate combined light to be incident on another end of the vapor cell;
• a reflector configured to reflect the combined light that has passed through the vapor cell and to direct the reflected combined light to be incident on the one end of the vapor cell;
• an electromagnetic wave generator configured to generate an electromagnetic wave to be incident on one side surface of the vapor cell;
• and
• a reflected light detector configured to detect reflected light released from the vapor cell,
• wherein the reflector is disposed such that the combined light that has passed through the vapor cell is reflected and the reflected combined light is incident on the vapor cell in a direction opposite to a direction of travel of the combined light before being reflected, thereby forming a standing wave of the combined light in the vapor cell, and
• wherein an angle at which the irradiation light is incident on the vapor cell is adjustable such that reflected light is released from the vapor cell.
