How does a grating work?



Grating technology combines digital technology with traditional print technology to create different special effects. It can display lifelike three-dimensional worlds, smooth animated sequences, and stunning transformation effects on a flat surface.

A grating is a thin sheet made up of strip-like lenses, and its working principle is based on the refraction and diffraction of light. When we observe from one side of the grating, we can see an image on a fine line on the other side of the sheet, and the position of this line is determined by the viewing angle.

If we arrange multiple images printed on the back of the grating sheet according to the width of each lens and in a sequential order based on the position of the lenses, we will see different images when observed through the lenses from different angles. This effect is achieved by utilizing the diffraction of light and the optical properties of the lenses, creating a sense of depth, flow, and change.

This technology is similar to the principles used in movies, but different. Movies create animation effects by quickly playing consecutive still frames. Grating technology, on the other hand, presents different images by changing the viewing angle, giving a sense of three-dimensionality and dynamism.

Based on this, due to the spacing between our own eyes, known as parallax, when we observe a three-dimensional object, each eye will see the object from a different angle and position, forming different images. These different images are transmitted to our brain and processed through stereoscopic vision, allowing us to perceive depth and a three-dimensional effect.

According to the principles of stereoscopic vision, if we can allow the left and right eyes to respectively see two images taken from different positions, we should be able to perceive a three-dimensional space. This is why in 3D movies or stereoscopic images, by displaying different images to the left and right eyes, we can feel depth and a three-dimensional effect.

This principle extends to the application of gratings, where a sense of three-dimensionality can be created by the special design of the grating and the variation in viewing angles. If the grating is placed vertically, due to the different viewing angles of the left and right eyes, they will see two different images, resulting in a sense of depth. This effect is achieved by simulating parallax, allowing our brain to perceive a three-dimensional effect.

It is important to note that both grating technology and the principle of stereoscopic vision utilize the characteristics of the human visual system to create a sense of depth. However, in practical applications, grating technology may require more precise design and manufacturing to ensure image quality and visual effects. Additionally, the perception of stereoscopic vision by the human visual system is also influenced by other factors such as lighting conditions, depth information, and motion perception.
In summary, by utilizing the principles of stereoscopic vision in the human visual system and the design of grating technology, we can create a sense of depth and three-dimensional effects Gratings provide us with a rich and immersive visual experience.
