In general the reflecting optical telescope has a large-aperture concave mirror for gathering and focusing light from astronomical bodies. As you've known, larger the size of mirror becomes, more difficult making such mirror with sufficient accuracy. Here is an alternative method to avert such difficulty;

Hello square17320509
Would not the reduction in aperture of the "scanning beam" reduce the light gathering ability of the telescope?

That's it
As mentioned in my site, it would require the exposure time longer than that of ordinary reflecting telescope.

May I suggest multiple scanning beams with computer integrated image software as a solution. Something similar to a DLP projection system but only in reverse.

Oh, that's a nice idea! But I think ususal CCD is still available for the image sensor rather than using expensive devices such as DLP.
