Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrared probe technology, and in particular to a near-infrared single probe. Background Technology
[0002] Currently, most infrared thickness measurements are installed using a through-beam method. The disadvantages are: 1. Frequent adjustments are required during installation to ensure the accuracy and stability of the optical path; 2. Sufficient space is needed to ensure a suitable optical path; 3. For irregularly shaped or uneven surfaces, it is difficult to find a suitable installation location to ensure the accuracy of the optical path. Therefore, a near-infrared single-probe design is needed to solve these problems. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a near-infrared single probe.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A near-infrared single probe includes a probe and a detection material. A transmitter body and a receiver body are fixedly installed inside the probe. A plano-concave mirror is connected and installed inside both the transmitter body and the receiver body. An infrared transmitter and an infrared receiver are respectively connected and installed on the top of the transmitter body and the receiver body.
[0006] Preferably, a reflector needs to be placed at the bottom of the detection material. Whether to place a reflector behind the material depends on the specific material requirements and can be chosen to improve the reflection efficiency.
[0007] Preferably, both ends of the transmitter body and the receiver body are provided with a fine-tuning screw to fine-tune the deflection angle of the transmitter body and the receiver body to achieve the best reflection effect.
[0008] The beneficial effects of this utility model are:
[0009] This invention employs a single-probe near-infrared structure, which is simple and lower in cost; it is easy to install and use; it offers better convenience; it requires less space; and the single probe allows for more flexible adjustment of angle and position, making it easier to adapt to the measurement needs of objects of different shapes and enabling more accurate acquisition of object information.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: Refer to Figure 1-2 A near-infrared single probe includes a probe 1 and a detection material. A reflector needs to be placed at the bottom of the detection material. Depending on the material requirements, it is necessary to choose whether to place a reflector behind the material to improve the reflection efficiency. A transmitter body 2 and a receiver body 3 are fixedly installed inside the probe 1. A fine-tuning screw 5 is provided at both ends of the transmitter body 2 and the receiver body 3 to fine-tune the deflection angle of the transmitter body 2 and the receiver body 3 to achieve the best reflection effect. A plano-concave mirror 4 is connected and installed inside the transmitter body 2 and the receiver body 3. An infrared transmitter 6 and an infrared receiver 7 are respectively connected and installed on the top of the transmitter body 2 and the receiver body 3.
[0015] Working principle: The infrared emitter 6 emits near-infrared light, which is converted into a parallel beam by the plano-concave mirror 4 inside the emitter body 2. This parallel beam hits the material and is reflected back to the receiver body 3 inside the probe 1. The receiver body 3 is also equipped with a plano-concave mirror 4, which can focus the near-infrared parallel beam into a point and hit the infrared receiver 7. Depending on the different material requirements, a reflector can be set behind the material to improve the reflection efficiency.
