Abstract
A flat panel detector is provided, which includes a base substrate and a plurality of detection regions arranged in an array on the base substrate, where each detection region is successively provided with a photosensitive sensor and an optical structure along a direction away from the base substrate; the optical structure includes a condensing unit and a light filtering unit, where the condensing unit is used for receiving the near-infrared light and ambient light emitted by the laser light source and performing condensing, and the light filtering unit is configured to shield the ambient light and transmitting the near-infrared light; a photosensitive sensor which includes an amorphous silicon photodiode and a thin film transistor, where the amorphous silicon photodiode is configured to convert the near-infrared light transmitted by the light filtering unit into an electrical signal.
