Title: Electron beam profile measuring apparatus for crt
Inventor: KATO MAKOTO
IPC: G01R31/24
Filed: 1992-08-26
Abstract: PURPOSE:To measure true profile of electron beam by removing high band cut-off frequency components from two-dimensional power spectrum of an electron beam image and then performing two-dimensional inverse Fourier transform. CONSTITUTION:A deflecting coil 7 in a CRT 1 to be measured is controlled through a deflecting circuit 3 to perform raster scan and an image data 2 picked up through a camera 8 is binarized by a binarization circuit 12 and stored in a memory 13. An FET operating section 14 subjects the image data to two-dimensional Fourier transform while a cut-off frequency determining section 15 determines cut-off frequency fcut which is then fed to a filter section 16. Horizontal and vertical constant current sources 4, 5 control the deflection coil 7 to still an electron beam which is then imaged through the camera 8. The binarization circuit 12 does not encode the image data but stores the image data, as it is, in the memory 13 and the FET operating section 14 subjects the image data to two-dimensional Fourier transform. The filter section 16 determines the product of a transfer function Z(s) set at the cut-off frequency fcut and power spectrum F1(s) and an inverse FFT operating section 18 subjects the product data to inverse Fourier transform thus producing a data Q representative of the profile of electron beam.
