1. A full spectrum recognition image sensor, comprising: a sensor substrate, photosensitive parts set on the sensor substrate and arranged in a straight line, a lens set on an upper portion of the sensor substrate, a light source set beside the lens, a framework for accommodating said sensor substrate, said lens and said light source, and an upper portion of the framework having a light-transmitting plate for carrying an original object, wherein the light source is a full spectrum light source for emitting light including ultraviolet light, visible light and infrared light, and the photosensitive parts on the sensor substrate consist of two parts, in which one of the two parts is a reflected light photosensitive part for receiving reflected light information generated by irradiating the original object with the light source, and other of the two parts is an exciting light photosensitive part for receiving exciting light information generated by irradiating the original object with the light source.
