What is the principle of bow and arrow physical sight?

The principle of bow and arrow physical sight is that light travels along a straight line. The eye, the standard instrument and the target are on the same line, which is commonly known as the three-point line.

In addition, there is now a holographic sight with a built-in red dot sight.

Internal red dot sight: A new generation sight, also known as the red dot sight manual, projects a aiming point or a line of sight on the mirror surface of the sight through electronic imaging. When the shooter aims from the sight, the aiming point (usually red or green) can directly hit the target, which is mainly used in modern entertainment shooting projects.

Holoscope: Holoscope, the full name of which is laser holographic diffraction mirror, is a revolutionary fast sight that directly observes the impact point and takes the impact point as the aiming sign. Aim fast and shoot accurately. Holographic sights aim at two points and one line, not the traditional concept of three points and one line.
