Through the Lens: A Look at Two Conflicting Mediums

Chapter 1 Introduction Photos have various uses throughout the course. Whether it is art, hobby, passion or homework, many people encountered digital cameras in their lives. These numbers will increase dramatically if you clearly contrast the frequency with which people use their cell phone camera. Why are these two shooting devices very different? This is the focus of my advanced project. Along with the continuous development of technology, many people predict that photos will soon be the past.

Last night when I sat at the corner of the sofa and reply to comments and e - mails, I stopped and saw the moon outside the window. Previously it was beautiful. I tried to take a picture with a camera, but it looks like a headlight. The lens is not as complicated as to capture the shadow of the surface of the Earth's heavenly partner, but it can be seen with my eyes. Ancient masters are deep and subtle. Their wisdom is immeasurable. There is no way to explain it; we can only explain its appearance. When someone crossed the cold flow, they were very cautious. Please beware of soldiers who are in the enemy's territory. Be polite as a guest. Liquid melts like ice. It can be molded into wood pieces. It was recognized as a valley. Transparent like a glass of water. Lao Tzu

In another aspect, the lens is part of a transparent refractive medium (ie glass) defined by two surfaces, at least one of which is spherical. It helps to form an image as it passes through the medium. In the excerpt of this article, we will explain the difference between the mirror and the lens in detail. Convex mirror: The mirror reflecting from the surface is a convex mirror. In such a mirror, the inside is painted and the outside is polished, which reflects the image. It is a divergent mirror that forms a virtual upright image of the object placed before it

The parallel rays are focused when passing through a lens having a convex spherical surface or when reflected from the surface of a spherical concave mirror. The distance from the lens (or mirror) to the focal point is called focal length f. This is a single number characterizing the optical properties of the lens or mirror in question. The optical path does not depend on the light propagation direction. Thus, for example, since parallel rays are focused by a convex lens at a distance f from the lens, the light emitted from a distance f away from the lens will be converted into a parallel beam. The lens used in this way is called a collimator, and the generated collimated beam is called collimated light.
