Hi,
This is my first post here.
I like these sorts of scanning cameras.
Reminds me of stuff developed in South Africa by Eloptro for the military during the military sanction era when night vision devices were not available for import. They used a hollow rotating polygonal mirror. This scanned the view sideways across a bunch of sensors (perhaps 8-16 not sure) using the inside of the mirror. Each facet of the mirror was at an angle and they would sweep the gaps in between the sensors to multiply the scan lines by the number of facets (perhaps 6 to 16 of those). The outside of the mirror was used to image a row of leds into the view finder optics and used eye persistence to form an image. So it painted it in a comb fashion but used the angular and tilt alignment of the inside and outside of the hollow mirror to synchronise the sensing view with the observing view. The mirror could be spun as fast as the sensors could handle and you could use as many sensors as you could justify price and power for. They later went on to copy 2nd and 3rd generation channel plate image intensifiers as the night sight developments progressed.
Not sure if the following article has been mentioned here. I use Sci-hub to breach the paywall. doi:10.1117/12.958943
Dual Waveband Infrared Scanning Radiometer For Use With Rocket Motor Plumes
http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=1230080It has some nice details about the cameras. Mentions 235 kHz nominal max pixel rate. They chose 207ksamples/s for a 60 x 90 field. The dynamic range is or the order of 60 to 80 dB and they used a 10 bit ADC to quantise the data and save to high speed tape for later retrieval.
They mention that the fuzzy interlacing takes 6 frames to repeat and is not hard synchronised but I got the feeling that two frames would give a pretty full image.
The shutter (possibly optional) seems to be well synchronised to the vertical scanning and reflects the sensor back for a cold reference.
That is all for now.
EDIT:
I forgot to mention that I thought it might be possible with modern sound card and super software to decode the data with just the video signal. The slow scan TV , the HAM radio people have been doing it for a while and it might make these nice old cameras more usable if no special control box (besides PSU would be required to get data out.
