Title: Automatic focusing method for scanning type microscope
Inventor: FUKUHARA SATORU
IPC: H01J37/21
Filed: 1993-03-15
Abstract: PURPOSE:To perform automatic focusing with high accuracy by focusing a charged particle beams or light with an objective lens and stepwise changing the focusing condition of a lens when a sample is scanned to obtain a secondary scanning image, storing a scanning obtained image into an image memory and controlling a focal position by the signal of the image. CONSTITUTION:When automatic focusing is performed, a signal of large contrast is used as a secondary signal from a sample to differentiate and cumulatively add it. For that reason, an objective lens control circuit 14 is newly provided so that the arbitrary current region of an objective lens 13 may be increased and decreased with arbitrary steps, and it is controlled with a computer 17. Thereby, a scanning image corresponding to each current is stored into an image memory 16 to find out such a current of lens that the cumulative additional value of a difference corresponding to each scanning image to be obtained becomes maximum. Thereby, the large locus of an amount of signal can be set to speed up the automatic focusing.
