There were a number of continuous projectors using mirror systems; the Mechau was probably the best known, but there were others going back at least to the '20s. None were very widely used.
The BBC used the Mechau for telecine at one time, and also did basically the same thing in reverse for film recording. This continued into the early '50s. The BBC recently released a 3 DVD set of everything that survives of 'Quatermass'. It seems that, so far as anyone can tell, of the first series only the first two episodes were ever recorded, but these were done on a Mechau, so it is possible to see what the results looked like. The second series was recorded on a suppressed field recorder, and the third one on a stored field recorder, so it is possible to see the results from three generations of recording equipment.
There's a picture of the Mechau recorders towards the bottom of this web page , and a frame of the main titles from the output can be seen just above. The results on the DVD actually look rather better than this frame does. There was a considerable improvement in each generation of equipment, though the vertical resolution of the supressed field recorder is somewhat lacking; British television in those days was only 405 lines, so discarding half of them was not really a good idea. I need to try to find some examples from partially stored field and fast pull down recorders.
Moving into the colour era, some of the best 16mm transfers I saw were from the Rank 'Laserscan' system.
Unfortunately, not much early television equipment seems to have been preserved.
