light phaser

[Martin Czech]

While we are on the phasing subject...  Are there any machines that use
LDR for voltage controlled phasing.  

This light stuff is new to me, i know only basic theory.

It is said that LDRs offer low noise, so this would be interesting.
The LED for the light controll could be connected in series, one
current generator (linear?) should be sufficient for ~8 stages (15V).
It is said that LDR circuits have a bit slow response towards the "off"
state, well it takes some time to get rid of all carriers.  Is this a
problem for moderate modulation , say 1:1000 ?  It needn't be so fast
for a phaser anyway.

There must be a kind of saturation effect, if the light is increased to
some point the resistance won't drop any more. Has anybody any
experienced with this?
