Actinography

Actinograph (from the Greek aktis, aktinos - ray and graphо - write, depict) is a device for recording changes in the intensity of solar radiation.

The actinograph consists of a sensitive element that senses solar radiation, an amplifier, a writing device and a clock mechanism for moving the chart tape. A thermoelectric converter (thermopile) is usually used as a sensitive element, heated by solar radiation incident on it. The thermo-EMF is converted by the amplifier into a voltage proportional to the intensity of solar radiation. This voltage is applied to a recording device, which draws a curve of solar radiation intensity on a moving chart tape.

Actinographs are widely used in meteorology for continuous recording of solar radiation intensity, as well as in solar activity studies.

Of course, here is a possible article on the topic "Actinograph" with a description: What is an actinograph? An actinograph is a device that is capable of visualizing asteroids and other bodies in the Kuiper belt based on their gravitational effect, forming a gravitational well inside which the braking of cosmic bodies occurs.

At the heart of the actinograph is a telescope connected to a system of mirrors and polarizing filters, which allows you to record the gravitational field of the atmosphere and its particles, as well as study celestial objects located in Earth orbit. It can be used both to detect asteroids and to study the overall influence of other planets in our solar system on its orbit. ***What can Actinograd do?*** The actinometer contains the following parts: - Signal input and digital processing module; - Input module; - Analog signal processing module; - Measuring device.

__An actinograph is a__ apparatus for studying the structural and functional characteristics of protein solutions by recording scattered light. This device records the intensity distribution of scattered laser light along the axis of the sample. By changing the operating mode of the device, it is possible to study the static and dynamic properties of biopolymers and conduct qualitative and quantitative analyses.

Actinographs are instruments that are used to study the electrical properties of gas discharges. They are often called actinometers because they use acts of light to measure the electrical characteristics of gases.

The actinograph is one of the main instruments of astrophysics and can be used to study the structure of the universe. In the past, actinographs were used to analyze planetaries
