interferometry...

Only because it gets no atmospheric interference, which most of the ground based telescopes do.
The atmosphere blocks and distorts light. Telescopes in space don't have that interference. This allows them to see farther and to get clearer, more detailed images.
Echoes of sound and images in a mirror involves sound waves and light waves respectively being reflected off a surface.
For the study itself the patient lies very still for approximately 30-60 minutes. A camera is moved across the patient's body to detect and capture images of concentrations of the gallium. The camera picks up signals.
Interferometry
Eye Q works by showing you a series of images and graphics training you to pick up signals to the brain quicker. After you do the images for a while, you can learn the words.
Laser interference
The way in which the information is encoded is the difference between a digital and an analog television signal. Traditional television signals are prone to fading, ghost images, and static. A digital television signal produces a crystal-clear picture and sound without fading or interference.
NON-interference. Recommended timing belt replacement is every 60,000 miles. See this website: > http://www.familycar.com/CarCare/Images/GatesTBR.pdf <
Form images from sensory signals.

It is called the RETINA
Because of the atmosphere. The atmosphere distorts light (this is also why stars 'twinkle'), where as the HST, free from this, faces no interference.
The optic nerve carries signals (images) from the retina to the brain.
Astronomers improved radio images by connecting telescopes. If two radio telescopes are separated by distance but are connected electronically, their signals can be combined using a computer. The resulting images are as good as if one telescope were used that was as big as the distance between the two. This method is called interferometry.
Viewing high quality images of sunsets from around the world can be found on the web. Sites that host these images include Improve Photography, Gizmodo, and Photography Blogger.
