How work a DVOR?

The Doppler VOR DVOR is the second generation VOR, providing improved signal quality and accuracy. The REF signal of the DVOR is amplitude modulated, while the VAR signal is frequency modulated. This means that the modulations are opposite as compared to the conventional VORs. The frequency modulated signal is less subject to interference than the amplitude modulated signal and therefore the received signals provide a more accurate bearing determination.

The Doppler effect is created by letting the VAR signal be «electronically rotated», on the circular placed aerials, at a speed of 30 revolutions per second. With a diameter of the circle of 13.4 meters, the radial velocity of the VAR signal will be 1264 m/s. This will create a Doppler shift, causing the frequency to increase as the signal is rotated towards the observer and reduce as it rotates away with 30 full cycles of frequency variation per second. This results in an effective FM of 30 Hz. A receiver situated at some distance in the radiation field continuously monitors the transmitter. When certain prescribed deviations are exceeded, either the IDENT is taken off, or the complete transmitter is taken off the air.

How were cameras back then?

It is believed that the camera was invented during the early 1500's. And I'm not talking about the high technology, snapshot camera we have today lol. The first unsophisticated camera was called the camera obscura, which meant dark chamber. Artists were the only people who used the camera as a tool mostly to help them sketch scenery. They would trace the shapes and lines, and then color the picture they took.

The camera worked by light entering a tiny hole on one side of the dark box that was big enough to fit a grown human being. The light formed an image on the opposite wall. The picture was an upside-down image of the scenery outside the box. .-.

During the 1660's the length of the camera was reduced to around two feet. A lens placed over the holes made the image larger and sharper. A mirror inside the camera reflected the image onto a piece of ground glass at the top of the camera. The camera obscura provided a way to project an image on a wall or a screen, but this procedure wasn't permanent. Artists still had to trace the image to preserve it. THX :D
