| 摘要 |
The invention relates to a gastrointestinal electronic pill protected by a biocompatible outer capsule that is resistant to the environment of the digestive system, comprising: a light source (4); means (5) for dividing the light beam, directing same to the reference arm (6) and the sampling arm (9); a group delay element (24) that can be adapted according to the distance from the tissue to be analysed; optical movement means (7) that move the point at which the light beam (30) from the sampling arm (9) intersects the tissue; an optical system (8) that focuses the light beam (30) from the sampling arm (9) on the tissue; interference means (10) that produce an interference between the reflected light; a detector (11) that receives said interference; processing means (2) which process the information obtained by the detector (11); and power supply means (3) for powering the pill without a physical connection to the exterior. |
