Abstract

La presente divulgación proporciona un sistema de exploración de rayo de energía dual, un método de exploración de rayo de energía dual, y un sistema de inspección de rayo de energía dual, y se refiere al campo de la detección de generación de imagen de exploración de radiación; el sistema de exploración de rayo de energía dual comprende una fuente de rayo y un filtro, en donde la fuente de rayo se utiliza para emitir un rayo de alta energía y un rayo de baja energía; el filtro comprende una porción de filtración de baja energía y una porción de paso de baja energía; cuando la fuente de rayo emite el rayo de alta energía, la porción de filtración de baja energía del filtro queda alineada con una dirección de salida de la fuente de rayo, de manera que una parte de baja energía del rayo de alta energía es filtrada, y una parte de alta energía del rayo de alta energía es penetrada; y cuando la fuente de rayo emite el rayo de baja energía, la porción de paso de baja energía del filtro queda alineada con la dirección de salida de la fuente de rayo, de manera que el rayo de baja energía es penetrado; por lo tanto, se puede mejorar una capacidad de transmisión del rayo de alta energía sin afectar una capacidad de resolución de cable espacial del rayo de baja energía, garantizando tanto un índice de capacidad de transmisión como un índice de capacidad de resolución de cable espacial, de manera que el rayo de energía dual puede utilizar de manera suficiente la diferencia de sus características de penetración para identificar un objeto inspeccionado para lograr los propósitos de la inspección de seguridad.
