Problems solved by technology

[0002] Optical scattering includes three types of forward scattering, backward scattering, and side scattering. In the current teaching and research devices for light scattering, each device can only perform one form of scattering, or only forward scattering. Scattering, or only backscattering, the existence of this device has led to a lot of waste of money and time, for example, when purchasing scientific research or teaching equipment, it is necessary to purchase a set for forward scattering and backscattering, if it is used For students' experimental learning, it may be necessary to purchase dozens to hundreds of units separately. If the school purchases parts by itself, and the teacher or students assemble the experimental device by themselves, it is necessary to assemble different experimental devices for different directions of scattering, which is too expensive. time, and in many cases, students are often required to observe both forward and backward scattering at the same time. This comparison can be more vivid and specific, which is easy for students to understand and master, but the existing devices obviously cannot meet this demand

Embodiment Construction

[0013] The forward scattering and back scattering compatible device of the present invention will be described in detail below with specific embodiments.

[0014] Attached figure 1 Among them, 1 represents continuous laser, 2, 3, 4 represent the same scattering medium, 5 represents beam splitter, 6, 7, 10, 11 represent polarizing beam splitter, 14, 15 represent total reflection mirror, 8, 13, 16, 18 indicates a quarter wave plate, 12 indicates a small aperture diaphragm, 9 indicates a polarization rotation device, and 17 indicates a controller.

[0015] The continuous laser 1 emits a continuous linearly polarized laser beam, which passes through the polarization rotating device 9 and is incident on the beam splitter 5. After passing through the beam splitter 5, it is divided into two laser beams, one of which passes through the polarization beam splitter 6, four The half-wave plate 16 enters the scattering medium 2 and generates relatively weak forward scattered light beams and ba...

Abstract

The invention discloses a forward scattering and backward scattering compatible device based on continuous laser beams. The device is characterized in that forward scattering and backward scattering can be realized simultaneously, or single forward scattering or single backward scattering is realized optionally.

Description

Technical field [0001] The invention relates to a light scattering experiment device, which belongs to the technical field of optoelectronics. Background technique [0002] Optical scattering includes three types of forward scattering, back scattering, and side scattering. In the current teaching and scientific research devices used for light scattering, each device can only perform one form of scattering, or only forward scattering. Scattering, or only backscattering, the existence of this kind of device has caused a lot of waste of money and time. For example, when purchasing scientific research or teaching equipment, you need to purchase a set of forward and backscattering. If it is used For students’ experimental learning, it may be necessary to purchase dozens to hundreds of units. If the school purchases parts by itself and the teacher or student assembles the experimental device, it is necessary to assemble different experimental devices for scattering in different directi...
