The present invention relates to a method for detecting an image in an image detector to obtain a clear image having reduced distortion. For this, the shape of the edge part of the image input aperture of a 2D image detector used in a terahertz band lower than the frequency of an infrared ray is processed with a preset shape. So, a diffraction pattern is not shown on a photographed image or contrast is weaken. |
