However, radio telescopes and optical telescopes actually work very similarly, and sometimes radio telescopes do have secondary reflectors. tion of telescopes. The future large optical telescopes like TMT, are likely to ﬁll the major gap that is left by the current generation of optical telescopes. 2.

Receiver ○The interferometer samples V(u,v) in the spatial frequency and then such signal is transferred via optical fber to a super computer (IBM – Blue Gen
Radio waves have low frequency and long wavelength compared to other types of electromagnetic energy. To detect these wavelengths, a radio telescope is used
These long waves are in the radio region of the electromagnetic spectrum. Because radio waves are larger than optical waves, radio telescopes work differently
We introduce the most general types of radio telescopes and describe how these operate; starting from The signal amplitude V(t) is a stationary random variable, and The antenna is analogous to the lens of an optical telescope. It
6 Mar 2019 You've probably heard of radio telescopes, but do you know how they work and about some of the extreme radio technology involved? Most people know telescopes as optical instruments for looking at Vn = √(4kTBR).

To get comparable resolution to an optical telescope with wavelengths that are a million times longer we would need a telescope a million times larger. So we link radio telescopes together - to make a single telescope.
Only, instead of picking up visible light waves, they pick up the really short waves or the really long ones that are the radio waves or the X ray waves.

Unlike optical telescopes, which view a range of wavelengths, radio telescopes view one wavelength at a time, and build up a contour map of the intensity of each wavelength. Using radio telescopes, scientists connected optical atomic clocks across Earth Transportable radio telescopes could provide global high-precision comparisons of the best atomic clocks.

So. Why the fundamental difference? Radio telescopes that work with mm wavelength band now have multi-pixel detectors.
