Analysis of prismatic reflective film’ s technology

With the rapid development of society and technologies, traffic, costumes and billboards and other fields have a great increasing demand for the prismatic reflective material. However,the Chinese manufacturer doesn’t attain the crucial technologies because of the difficulties to produce and their small size. With the target of bridging the gap of technologies between China and other aboard markets,it is the time to research the structure of prismatic reflective material’s optical function and processing.

Let’s focus on the following paragraph about the way to research the prismatic reflective material.

This passage will take the structure of prismatic reflective material as the object of research. And we will investigate the normal-incident optical properties of prismatic reflective sheeting, the oblique-incident optical properties as well as the optical properties of its array. What’s more, the improved structure of the prismatic reflective film also will be analyzed. At the same time, an ultrasonic bending vibration planning test system is built to study the processing of its structure.

So now, we come to the contents of this examination.

The main contents are as follows:

(1)First of all, we adopted geometric optics and mathematical analysis methods to analyze the normal incidence optical trajectory of a cubic corner cube. And then we could utilize this model to analyze the way the invalid light was emitted and the reason why the invalid light was produced. Next, we studied the effect of failure on the bottom surface of the prismatic reflective sheeting, which showed that the side area close to the vertex has a greater impact on the effective area of the cone than the outer edge area.

(2)With the intention of knowing the reflection effects of the prismatic reflective sheeting when the light was incident at a certain angle, we took advantage of mathematical analysis and software simulation methods. Frankly speaking, we classified the refracted light of the prismatic reflective sheeting at first and then we were trying to comprehend the restrictions of the total reflection condition on the reverse vector of the refracted light.

(3)In order to grab the correct and exact data of prismatic reflective film’s reflection angle, our team used optical software simulation to analyze how the retroreflectivity of obliquely incident light on a specific plane changes with the incident angle, which demonstrated that when the incident angle of light that can be retroreflected on a specific plane is in the range of 50°to 70° or in the range of 67 to 69°, a secondary peak would appear in the retro-reflectivity.

(4)Secondly, our group utilized the optical simulation software to analyze how the reflectivity of a single invalid area‘s reflectivity changed with the thickness of the layer in order to illustrate the great connection between connecting layer and array reflectivity. After the communication among us, we got the reflectivity curve with connecting layer thickness, which would assist us to obviously know the connection between them.

(5)Finally, we established a cubic corner cube array codel so as to figure out the cause of the growth of invalid light in prismatic reflective arrays. Then, we analyzed the rules of the invaild lights in the array of connected layers after we understood the characteristics of light arrangements. The examination showed that invalid light in the array can be reflected back in the direction opposite to the incident direction.
All these are all about the results of prismatic reflective sheeting technologies. Wish the readers could get inspiration from this passage.

EXCERPT:

Prismatic reflective sheeting plays a more and more important role in our daily life.With the purpose of exploring its capability and applications, we have a research its angle of incidence, knowing the different effects of reflection according to the different angles, which will be a great assistance to our production and processing.
