Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
AN IMAGE INTENSIFIER DEVICE COMPRISING, A FIRST RADIATION RESPONSIVE SURFACE DISPOSED TO RECEIVE AN INCIDENT RADIATION IMAGE, A SECOND RADIATION RESPONSIVE SURFACE DISPOSED TO RECEIVE THE RESPONSE FROM THE FIRST RADIATION RESPONSIVE SURFACE, A RADIATION AMPLIFYING MEMBER BEING LOCATED BETWEEN SAID FIRST AND SECOND RADIATION RESPONSIVE SURFACES WITH THE INPUT END OF SAID AMPLIFIER MEMBER RECEIVING THE OUTPUT OF SAID FIRST RADIATION RESPONSIVE SURFACE AND THE OUTPUT END OF SAID AMPLIFIER MEMBER DIRECTING THE AMPLIFIED IMAGE TO SAID SECOND RADIATION RESPONSIVE SURFACE, AND RADIATION ATTENUATING MEANS DISPOSED ON THE OUTPUT SIDE OF SAID AMPLIFYING MEMBER AND HAVING SPATIAL DENSITY VARIATIONS DISPOSED SO THAT THE RESULTING ATTENUATION OCCURRING TO THE AMPLIFIED SIGNAL WILL PRESERVE SIGNAL FIDELITY AND EQUALIZE RADIATION CONVERSION AND TRANSFER MECHANISMS WITHIN SAID DEVICE.
