A night vision scope. We know about it from American action movies, for example. We have often watched a special agent point this device into a dark space, and silhouettes of criminals appear on the screen. "Capable" device, a necessary device that commands respect for the one who invented it.
You will be surprised, but the night vision sight owes its existence to Mikhail Vasilyevich Lomonosov. It was him who first came up with the brilliant idea to create a device "to condense light". He called his invention "night vision tube". And it was in 1758. In his article "The Physical Problem of the Night Vision Tube", describing this device, he wrote that it serves to "distinguish at night rocks and ships". That's it and no other way!
Modern "night vision tubes" are now called "night vision scopes". PULSAR Digisight N750 digital night vision sight is considered to be the best of them. It is a short tube with a special display. On the display a person sees a mark in the form of a cross with a dot in the middle. The color of the dot can be changed from red to green or vice versa. However, the shape of the marker can be changed at will by downloading the necessary form from the site of the device manufacturer, and then simply load the file into the sight's memory.
But if it weren't for World War II, it's unlikely that the night vision device would have changed its original purpose of tracking ships and rocks. After all, war doesn't have a lunch break or a nap. Sometimes the attacks took place at night. And in order that the equipment could move freely in conditions of zero visibility, without colliding and not crushing each other, in Germany in 1936 was invented a special night vision device, which were equipped with tanks. From the family of night vision devices, the night vision sight was soon separated. In 1944, the first batch of infrared sights was produced.
