Default Re: Colour mixing in mechanical television

The mirror will not be perfect, leading to a backgound light. This is not a contrast ratio as we know it ,as it is the modulated source so might be distracting in intended black areas of the 'screen'.
Assuming the mirror is set in a blackened box, it is possible the optimal light level may not be that difficult to achieve...
all the best Peter
