Abstract
A sensing apparatus adapted to detect samples is provided. The sensing apparatus includes a light source, a light-penetrating medium, a metal thin film, and a plurality of sensors. The light source is adapted to provide a light beam. The light-penetrating medium has an optical surface. The metal thin film is disposed on the optical surface of the light-penetrating medium. The samples are adapted to be placed on the metal thin film. After the light beam enters the light-penetrating medium from a side away from the optical surface, the light beam is adapted to be totally internally reflected at the optical surface, such that surface plasmon resonance occurs at a surface of the metal thin film to excite the samples. The samples are adapted to emit signal light beams after being excited. The plurality of sensors are adapted to sense the signal light beams. The metal thin film is disposed between the plurality of sensors and the light-penetrating medium.
