| titleOfInvention | Methods for detecting particulate radiation |
| abstract | The present invention discloses a method for detecting particulate radiation. When particle radiation such as electrons is detected with a pixelated detector, a cloud of electron/hole pairs is formed in the detector. Using the signal caused by this cloud of electron/hole pairs, the location of the impact is estimated. The inventors found that when the size of the cloud is comparable to or much smaller than the pixel size, the estimated position shows a strong bias to the center and corner of the pixel, and to the middle of the boundary. This hinders formation of an image with super-resolution. By shifting position or by assigning electrons to several sub-pixels, this bias can be counteracted, resulting in a more realistic representation. The inventors also found that by expanding the image, the Moire effect and interference in the image can be canceled out. This expansion is a reversible process as long as the image is sparse (nearly all pixels represent a bump or no bump). After expansion (effectively, spatial low-pass filtering), high-pass filtering can be used to homogenize the image. |
