[0002] With the widespread application of laser technology in industrial inspection, remote sensing, and medical fields, the demand for precise measurement of the reflectivity of target surfaces is increasing. Modern materials science requires more accurate tools for analyzing surface optical properties, especially for studying the diffuse reflectivity of rough surfaces, coatings, and composite materials.

[0003] An optical experimental instrument, as described in patent application CN201621206364.6, includes a semi-circular demonstration screen and a base. The demonstration screen has graduations and is connected to the base. A connecting hole is located at the center of the demonstration screen, through which it is rotatably connected to an optical base. The optical base can be a laser optical base or a solar optical base. A laser light source is mounted on the laser optical base, pointing towards the center of the demonstration screen. A solar mirror is mounted on the solar optical base and rotatably connected to it. The demonstration screen has a refractive mirror, or the base has a reflective experimental mirror, which can be a reflecting mirror or a diffuse reflecting mirror. The refractive mirror is a semi-cylinder, while the reflecting mirror and diffuse reflecting mirror are cuboids. This invention offers diverse functions, providing experiments on reflection, refraction, and diffuse reflection under laser and solar light sources; allowing dynamic observation of the experimental process; and the device is detachable and portable.

[0004] However, the aforementioned optical experimental instrument cannot effectively demonstrate the diffuse reflection of laser light on the surface of the workpiece specimen, resulting in poor observation results. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an observation box for laser diffuse reflection comparison; it solves the problem of poor observation effect of laser diffuse reflection of workpieces in the prior art, making the comparison more accurate and the observation effect more obvious.

[0006] This utility model discloses a laser diffuse reflection comparison observation box, comprising a box body; a top cover snapped onto the upper end of the box body; a control panel disposed on the upper end of the top cover; a mounting block fixedly connected to the box body; a colloidal particle box disposed on the outside of the box body; a material pump fixedly connected to the colloidal particle box; a material conveying pipe fixedly connected to the output end of the material pump; a nozzle fixedly connected to the material conveying pipe after passing through the side wall of the box body; a nozzle fixedly connected to the inside of the box body; a bracket fixedly connected to the upper end of the box body; a motor fixedly connected to the box body corresponding to the bracket; a high-speed camera fixedly connected to the output end of the motor; the high-speed camera rotatably connected to the bracket; and the high-speed camera electrically connected to the control panel.

[0007] Preferably, a black sponge is embedded on the inner side of the mounting block.

[0008] Preferably, a black rubber pad is fixedly connected to the lower end of the upper cover.

[0009] Preferably: a pair of electric cylinders are fixedly connected to the upper end of the cover; the output ends of the pair of electric cylinders are fixedly connected to the cover box; the cover box has an optical path channel; the cover box corresponds to the stage; and a resin plate coated with fluorescent material is attached to the inside of the cover box.

[0010] Preferably, the inner side of the box is coated with a black light-absorbing paint.

[0011] Preferably: the mounting block is threadedly connected to a screw; the upper end of the screw is rotatably connected to a slider; the lower end of the slider is slidably connected to the mounting block; and the upper end of the slider is fixedly connected to a clamping block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By setting up a high-speed camera, the diffuse reflection can be observed. At the same time, the inside of the chamber can be observed and recorded with the help of the high-speed camera, which can intuitively reflect the diffuse reflection of different specimens. By using the high-speed camera in conjunction with the colloidal particles sprayed from the nozzle, the Tyndall effect is utilized. The scattering phenomenon of light waves is more obvious when the diameter of the colloidal particles is close to the wavelength of the light wave, and the diffuse reflection of the laser can be recorded more intuitively. At the same time, by inputting colloidal particles of different diameters into the nozzle through the colloidal particle box, the wavelength of the diffuse reflection of the laser can be preliminarily determined, the comparison is more accurate, and the observation effect is more obvious.

[0014] (2) By setting up an electric cylinder, a housing, and an optical path channel, and by using a resin plate coated with fluorescent paint attached to the inside of the optical path channel, the light absorption of the resin plate can be compared to visually display the diffuse reflection, which improves the observation effect and reduces the difficulty of comparing the diffuse reflection of the laser.

[0019] Specific Implementation Example 1: Please refer to Figure 1-3 A laser diffuse reflection contrast observation box includes a box body 10; a top cover 15 is snapped onto the upper end of the box body 10; a control panel 16 is provided on the upper end of the top cover 15; a mounting block 11 is fixedly connected to the box body 10; it also includes a colloidal particle box 12 disposed on the outside of the box body 10; a material pump 13 is fixedly connected to the colloidal particle box 12; a material conveying pipe 14 is fixedly connected to the output end of the material pump 13; a nozzle 20 is fixedly connected to the material conveying pipe 14 after passing through the side wall of the box body 10; the nozzle 20 is fixedly connected to the inside of the box body 10; a bracket 22 is fixedly connected to the upper end of the box body 10; a motor 23 is fixedly connected to the box body 10 corresponding to the bracket 22; a high-speed camera 29 is fixedly connected to the output end of the motor 23; the high-speed camera 29 is rotatably connected to the bracket 22; and the high-speed camera 29 is electrically connected to the control panel 16.

[0020] Please see Figure 2 The mounting block 11 has a black sponge 18 embedded inside. A high-speed camera 29 is set up to observe the diffuse reflection. At the same time, the high-speed camera 29 can be used to observe and record the situation inside the box 10, which can intuitively reflect the diffuse reflection of different specimens. The colloidal particles sprayed by the high-speed camera 29 and the nozzle 20 utilize the Tyndall effect. The scattering phenomenon of light waves is more obvious when the diameter of the colloidal particles is close to the wavelength of the light wave, which can more intuitively record the diffuse reflection of the laser. At the same time, colloidal particles of different diameters are input into the nozzle 20 through the colloidal particle box 12, which can preliminarily determine the wavelength of the diffuse reflection of the laser, making the comparison more accurate and the observation effect more obvious.

[0021] Please see Figure 2 The lower end of the upper cover 15 is fixedly connected to a black rubber pad 26.

[0022] Please see Figure 2 The upper end of the cover 15 is fixedly connected to a pair of electric cylinders 17; the output ends of the pair of electric cylinders 17 are fixedly connected to the cover box 24; the cover box 24 has an optical path channel 25; the cover box 24 corresponds to the stage 21; and a resin plate coated with fluorescent material is attached to the inside of the cover box 24.

[0023] Please see Figure 2The inner side of the housing 10 is coated with black light-absorbing paint.

[0024] Please see Figure 3 The mounting block 11 is threadedly connected to the screw 19; the upper end of the screw 19 is rotatably connected to the slider 27; the lower end of the slider 27 is slidably connected to the mounting block 11; the upper end of the slider 27 is fixedly connected to the clamping block 28; by setting up the electric cylinder 17, the cover box 24, and the optical path channel 25, and by using the resin plate coated with fluorescent paint attached to the inner side of the optical path channel 25, the light absorption of the resin plate is compared to intuitively display the diffuse reflection situation, which improves the observation effect and reduces the difficulty of comparing laser diffuse reflection.

[0025] The control panel 16 is electrically connected to the high-speed camera 29. The data captured by the high-speed camera 29 is transmitted to the control panel 16, and real-time diffuse reflection images can be retrieved.

[0026] During operation, start the black rubber pad 26 and rotate the output end of the black rubber pad 26 to adjust the angle of the bracket 22 so that it is aligned with the specimen on the stage 21; first remove the black sponge 18, turn the screw 19 to lock the laser emitter between the clamps 28, then insert the wire into the hole of the black sponge 18, then put the black sponge 18 back on, and adjust the laser emission angle of the laser emitter so that the laser can irradiate the specimen;

[0027] After completing the preparation work, the high-speed camera 29 can be aimed at the laser irradiation point on the specimen, and the control panel 16 can be operated to control the exposure quantity and time delay of the high-speed camera 29 and other photographic data to capture the light spot generated by the laser diffuse reflection, which can be used as a reference for preliminary laser diffuse reflection comparison.

[0028] Because laser light produces diffuse reflection, the diffused light is difficult to observe clearly in ordinary air. At this point, the pump 13 can be activated to extract colloidal particles from the colloidal particle box 12 and spray them through the nozzle 20. These colloidal particles are a general term for fine colloidal particles that can be suspended in the air; this is a common substance in existing technology and will not be elaborated upon here. This creates moving colloidal particles in the air inside the box 10, artificially transforming the air inside the box 10 into a colloidal environment. Due to the Tyndall effect, colloidal particles in the air can form a bright path perpendicular to the light path when light passes through, which is then captured by the high-speed camera 29. By changing different specimens and observing the brightness of the path, the differences in diffuse reflection can be further revealed. By utilizing the Tyndall effect and different colloidal particle sizes, the wavelength of the diffused light can be determined using the size of the light spot captured by the high-speed camera 29, further improving the accuracy of diffuse reflection comparison.

[0029] When the requirements for contrasting the diffuse reflection of the laser on the specimen are not high, and only a visual representation of the test results is needed, a laser is emitted by a laser emitter. After the laser shines on the specimen on the stage 21, the electric cylinder 17 is activated. The output end of the electric cylinder 17 drives the cover box 24 to descend. After the cover box 24 descends, the laser shines on the specimen through the optical path channel 25. The resin plate coated with fluorescent paint, which is attached to the inner side of the optical path channel 25, absorbs the diffuse reflection generated by the laser on the specimen. After sufficient irradiation time, the resin plate inside the optical path channel 25 is removed and then replaced. The specimen is then replaced, and the same amount of irradiation time is applied. By comparing the light absorption of the fluorescent paint on the two resin plates, the diffuse reflection can be visually observed, providing a direct representation of the diffuse reflection on different specimens.
