As you know, the appointment of an optical telescope - to increase the angle under which the visible celestial body, and to collect as many rays of light coming from it. For nearly chetyrehsotletnyuyu history emerged and developed in accordance with the theory of two main types of construction: refraktornaya - and lens reflex - a mirror. This should add that in the first half of the twentieth century was invented radio telescope. Ask: is it possible to propose the following construction of the telescope through which significantly enhance our understanding of the appearance and structure of distant stars. Let us turn directly to the experience. Of Optics known that from any point on a visible body (stone reflecting light, or star), the rays of light are distributed at different angles and straightforward. These beams of light and transmit the information from each point of the object and the amount of it in general. If you start to increase the lens (lens) refractor or reflector mirror, then at their modern manufacturing is a technical limit, and thus there are errors, leading to a distorted picture of the investigated object. Way out of this difficulty, we vzgyad, is a telescoping design, the principle of which is based on the reception of information carried by parallel rays of light from the object. If you make a cylinder diameter of 5-7 cm and a height of 5-7 cm from the light absorbing solid (black) of the substance and then to do it fairly small (tubular) channels with diameter of about 10 photons (the smaller the better). Moreover, the channels will be sent from one end (the circle) to another, and strictly parallel to each and every height of the cylinder. It is necessary to achieve their maximum density. So we got a new lens. If the lens mounted into TV cameras, removing the pre-lens - we get the cameras telescope. The work of the telescope is as follows: light from the object will be taken by it in the form of parallel rays (which, let us have the information from his angle) beams under different angles gasyatsya in the process of light absorption by black-walled channels. Now, if you put this device in a remote star and taken to strengthen the signal and then submit it to the TV, we see the corresponding area (the diameter of the cylinder lens 5-7 cm) surface of the star on the screen. And it would be quite the same picture as if we saw a star in front of you and it is the same area. That is the scale of the reception facility does not change with distance from it and is 1:1. Then, to purchase optical information on the entire surface of the star, contacting us - you need to scan the entire visible surface of it. Received signal can be recorded. The device will be very sensitive to mechanical influences and so it is better to make the space. To achieve a similar effect to using bulky Polaroid, crossing close to 90 °, or direct transmission only parallel rays (the rest of the angles shown). The same principle applies to radio waves. Such an approach, only with a change in direction of the channels (radial) and applied to microscopy. And, as we have seen, described the application of the principles of optics can be very promising in the knowledge of the world material protected |
