Abstract:
A detection device is provided. The detection device includes a sensor base; a plurality of photoelectric conversion elements that are provided in a detection area of the sensor base and are configured to receive light incident thereon and output signals corresponding to the received light; a plurality of switching elements provided in the respective photoelectric conversion elements; a plurality of gate lines that are coupled to the switching elements and extend in a first direction; a first light source configured to emit first light having a first maximum emission wavelength; and a second light source configured to emit second light having a second maximum emission wavelength.
