    • A spectral image acquiring apparatus includes an optical filter on which light is incident; an image sensor including a two-dimensionally disposed pixel array for detecting the light via the optical filter; and a signal processing unit generating a difference-value image based on a detection signal from the image sensor. The optical filter includes a diffraction grating having a lattice pattern corresponding to one or more pixels on the image sensor. The signal processing unit calculates a difference value in an amount of received light between two adjacent pixels based on the detection signal from the image sensor, and generates the difference-value image based on the difference value. The difference value between the two adjacent pixels is varied depending on a difference in an interference point on the image sensor corresponding to a diffraction angle of the light that has passed through the diffraction grating.
    • 光谱图像获取装置包括光入射的滤光器; 图像传感器,包括用于经由滤光器检测光的二维布置的像素阵列; 以及信号处理单元,其基于来自图像传感器的检测信号生成差值图像。 光学滤波器包括具有对应于图像传感器上的一个或多个像素的格子图案的衍射光栅。 信号处理单元基于来自图像传感器的检测信号计算两个相邻像素之间的接收光量的差值,并基于差值生成差值图像。 两个相邻像素之间的差值取决于对应于已经通过衍射光栅的光的衍射角的图像传感器上的干涉点的差异。
