A telescope is a tool that uses the display of refraction of the reflected light or radiation safety and the image can be closer. The capture of light is a component, is the goal. The goal is a part of the telescope, seized by the light, offers an image of the object that is right. In general, the objective is either from a series of lenses or a concave mirror.
Now think of the possibility of using liquid mirror reflections return to our vision. The concept of a liquid mirror is comparable to the experience from the perspective of your image in a pool of water. However, a liquid mirror telescope, which is used to peer into the depths of the universe. At first glance, the concept of the telescope seems like something that is pulled by a large and very futuristic.
But the future is how astronomers recognize the potential employees of the telescope in place of a concave mirror in nature, usually in a reflecting telescope.
A History of liquid mirror telescope
Isaac Newton in the 17th century, the individual was the first to go on record opportunities for these telescopes. In his studies, he noted that the liquid is woven shell makes it a natural concave shape. This spinning, the liquid for the same type of concave mirror with a reflective surface through the telescope.
Unfortunately, his idea was ahead of their time. This is because the electric motor has not yet been invented. The electric motor would have been needed to give the rotation, the fluidity of its concave shape.
The first documented case of a telescope was set up in 1909. But it was not until 1982, a physicist by the name Ermanno Borra changed the design to improve the performance of the telescope. Such a telescope is located in British Columbia, Canada.
Structure of a Liquid Mirror Telescope
Fortunately, today, all technologies are available, and, in fact, the implementation of telescope mirror in practice. In particular, the liquid that is used, is 30 litres of mercury. Mercury is a shell concave segments. The Court itself is made of a hard plastic with polyester. The framework of the skin is a light metal.
The process
From the shape to the form required to secure the best reflection necessary for the antenna starts to spin. The rotation speed is about 7 revolutions per minute. This speed is maintained, as well as the proper distribution of mercury occurs.
Advantages and disadvantages
The only drawback, it was found that in the case of the use of a telescope mirror of the need that food to stay in parallel. This is obviously due to the fact that when the liquid is inclined gravitativ would sink at the end, tilted downward.
The advantage is that the field of thinking is extremely important. This section offers a greater ability to collect a larger, more visible light complete the main object. This larger space for reflection allowing greater distances in the galaxy.
