| 摘要 |
The invention relates to an arrangement for the optical transmission of an MR signal from an MR receiving coil (6) to a detection unit (22). The light of a light source (21) is applied, by way of an optical fiber, to an electro-optical modulator which consists of an electro-optical material which is arranged between two crossed polarizers (3, 5). Thus, a light signal which is amplitude modulated around zero is generated, the intensity of said light signal being proportional to the voltage induced in the MR receiving coil (6). The modulated light signal is then conducted from the electro-optical modulator to the detection unit (22) by way of an optical fiber.
