G'day all.
Whilst I've been thinking a lot about my solid state iconoscope camera project and the possibility of DIY iconoscope tubes having the right equipment handy and I've had an interesting idea flashing in my head and I wonder if it might work.
I was pondering on the possibility of making a vacuumless iconoscope type camera tube which instead of having a cathode ray gun scanning its beam across the photosensitive mosaic target inside a vacuumed tube, there will be a laser scanning its beam across across a photosensitive mosaic target made of material that will discharge to the laser beam hitting it converting the image projected on it into electrical impulses in the same fashion as the traditional iconoscope. This idea will eliminate the need of a vacuum in the tube and also eliminate the need of horizontal/vertical deflection coils. Of course I am guessing there will still be keystone trapezoidal distortion due to the 30 degree offset of the laser beam and it requiring variable horizontal scanning width from top to bottom. I have made a diagram of the tube to visually represent this idea which can be seen below.
Anyways those who read this thread I would love to hear your opinions of this idea and if it can work any knowledge you can provide to make it practical as my knowledge of designing the circuitry is very limited.
