[origin: US5631459A] PCT No. PCT/FR93/01120 Sec. 371 Date May 12, 1995 Sec. 102(e) Date May 12, 1995 PCT Filed Nov. 16, 1993 PCT Pub. No. WO94/13005 PCT Pub. Date Jun. 9, 1994A device for selecting a remanence of output screens of radiological image intensifier tubes. A luminescent screen (ES1) utilizes two phosphor materials (A, B) exhibiting different remanences and different emission spectra. Wavelength-selective optical filters (Fo) are associated with the luminescent screen ES1 in order to select a remanence chosen by transmitting the corresponding spectral band.
