space telescope design using artificial guide stars

Hi, I came across this article mentioning using cubesats or similar small satellites as a constellation of artificial guide stars for a next generation space telescope to have a laser feedback signal to maintain pointing accuracy on telescopes that don't necessarily have inherent pointing accuracy, ie cheaper telescopes: That reminded me of an idea I had before, in this thread from 2014: That is having a coded aperture between the telescope and the object(s) being imaged. I think the two ideas of artificial guide stars and coded apertures could be done by the same small satellite constellation around a large next generation satellite. cheers, Jamie

Hi,

A recently developed technology called COACH using coded apertures for optical telescopes (coded aperture correlation holography)

So you re-developed interferometry. Good job.

The huge mirrors are not there to increase resolution but to get more light to the sensor.
