    • A millimeter wave imaging apparatus includes: an imaging device including a plurality of millimeter wave sensors that are arranged in a planar manner and receive millimeter waves radiated from a subject to detect signal levels thereof; and an image data generation device that generates image data of the subject based on an output from each of the millimeter wave sensors constituting the imaging device. The millimeter wave imaging apparatus also includes: a temperature sensor that detects a temperature of the imaging device; and a storage device that stores, with respect to the each of the millimeter wave sensors constituting the imaging device, temperature characteristics data indicating a relationship between the temperature detected by the temperature sensor and the output from the millimeter wave sensor. The image data generation device obtains a deviation of the output from the each of the millimeter wave sensors from reference temperature characteristics based on the temperature detected by the temperature sensor and the temperature characteristics data stored by the storage device, corrects the output from the each of the millimeter wave sensors based on the deviation, and thereby generates the image data.
    • 毫米波成像设备包括:成像装置,包括多个毫米波传感器,所述多个毫米波传感器以平面方式布置并接收从对象辐射的毫米波以检测其信号电平; 以及图像数据生成设备,其基于构成成像设备的每个毫米波传感器的输出来生成对象的图像数据。 毫米波成像装置还包括:温度传感器,其检测成像装置的温度; 以及存储装置,其针对构成成像装置的每个毫米波传感器存储表示由温度传感器检测到的温度和来自毫米波传感器的输出之间的关系的温度特性数据。 图像数据生成装置基于由温度传感器检测到的温度和由存储装置存储的温度特性数据,获得每个毫米波传感器的输出与参考温度特性的偏差,校正来自每个毫米波传感器的输出 基于该偏差的毫米波传感器,从而生成图像数据。
