[0030] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] Figure 1 is a schematic top view of a laser testing device according to an embodiment of the present disclosure. Figure 1 The laser testing device of the embodiment of the present disclosure is used to test the laser emitted by the laser emitter 900. Optionally, the laser emitter 900 includes an optical fiber capable of transmitting and emitting laser. It is understandable that the laser emitter 900 of the present disclosure includes but is not limited to this, and other devices capable of emitting laser, such as laser emitting lamps, are also applicable to the present disclosure. The laser testing device includes a first optical information detection component 10 and a reflected light detection component 20.

[0035] Figure 2 Schematic diagram of the structure of some components of the laser testing device according to the embodiment of the present disclosure. Figure 2 The first optical information detection element 10 includes a light receiving portion 11 for receiving and reflecting optical signals, and is used to detect first optical information. Thus, when laser light is irradiated onto the surface of the light receiving portion 11, a portion of the laser light is received by the light receiving portion 11, and the first optical information of the laser light is detected, and a portion of the laser light is reflected by the surface of the light receiving portion 11 to form Fresnel reflection, so that the laser light is reflected and propagated.

[0036] Optionally, the first optical information detection element 10 is an optical power detection element, which may include a laser power meter. The laser power meter can receive the laser emitted by the laser transmitter 900, thereby detecting the power information of the laser, i.e., the first optical information, and forming a Fresnel reflection on the laser, thereby reflecting the laser. It can be understood that Fresnel reflection refers to the phenomenon that a portion of the light will be reflected when light is incident on the interface between two media with different refractive indices (such as the air-light receiving surface of the laser power meter). Ordinary laser power meters can detect the power information of the laser and Fresnel reflect a portion of the laser. The first optical information detection element 10 of the present disclosure includes but is not limited to this. Other devices that can detect laser information and Fresnel reflect laser are also applicable to the present disclosure.

[0037] The reflected light detection component 20 is disposed on a reflection path of the laser beam by the light receiving unit 11 to detect at least second light information based on the reflected light.

[0038] Optionally, the reflected light detection assembly 20 includes a time domain detection element 21 and / or a spectrum detection element 22. The time domain detection element 21 and / or the spectrum detection element 22 are arranged on the reflection path of the laser by the light receiving part 11 to detect the spectrum information and / or time domain information of the received laser.

[0039] That is to say, the laser reflected by Fresnel can be received by the time domain detection element 21 and / or the spectrum detection element 22, so that the time domain detection element 21 and / or the spectrum detection element 22 can obtain the second light information of the laser, such as the spectrum information and / or time domain information of the laser.

[0040] In some examples, the reflected light detection assembly 20 includes a time domain detection component 21. The time domain detection component 21 includes a photoelectric probe 231 and an oscilloscope.

[0041] It is worth mentioning that when the photoelectric probe 231 receives the reflected microwatt-level power of the laser, the oscilloscope can display the time domain information of the received laser. Therefore, the photoelectric probe 231 (i.e., PD probe) is arranged on the reflection path of the laser. The oscilloscope is connected to the photoelectric probe 231 to display the time domain information of the laser.

[0042] In some other examples, the reflected light detection assembly 20 includes a spectrum detection component 22. The spectrum detection component 22 includes a spectrum detector.

[0043] It is worth mentioning that when the jumper probe 232, i.e., the jumper head of the spectrum detector, receives the reflected microwatt-level laser, the spectrum detector can provide the spectrum information of the laser. Therefore, the jumper probe 232 of the spectrum detector is arranged on the reflection path of the laser so that the spectrum detector can obtain the spectrum information of the laser.

[0044] In other examples, the reflected light detection assembly 20 includes a time domain detection component 21 and a spectrum detection component 22. The time domain detection component 21 and the spectrum detection component 22 are respectively arranged on opposite sides of the laser emitter 900. The time domain detection component 21 includes the above-mentioned photoelectric probe 231 and the above-mentioned oscilloscope. The spectrum detection component 22 includes the above-mentioned spectrum detector.

[0045] As a specific example, when the first optical information detection element is implemented as an optical power detection element, the distance H1 between the reflected light detection component 20 and the first optical information detection element 10 is 5-10 cm, and the distance H2 between the time domain detection element 21 and the spectrum detection element 22 is 5 cm.

[0046] Thus, when the laser is irradiated to the light receiving part 11, and part of the laser is reflected by Fresnel on the surface of the light receiving part 11, the time domain detection element 21 and the spectrum detection element 22 located on opposite sides of the laser emitter 900 can both receive the reflected laser, and test the spectrum information and time domain information of the laser according to the reflected laser. It can be understood that the time domain detection element 21 and the spectrum detection element 22 of the present disclosure include but are not limited to this, and the above specific examples are only simple examples made to facilitate those skilled in the art to understand the present disclosure.

[0047] Therefore, when the present invention detects multiple parameters of the laser, such as power and spectrum, power and time domain, and power, spectrum and time domain, it only needs to irradiate the laser to the first optical information detection element 10 to test and obtain multiple parameter information of the laser, such as corresponding power and spectrum information, power and time domain information, and power, spectrum and time domain information. The present invention can test multiple parameters of the laser in one test, and the testing efficiency of multiple parameters of the laser is high.

[0048] In some embodiments of the present disclosure, the reflected light detection component 20 is arranged with adjustable height. For example, the time domain detection component 21 and / or the spectrum detection component 22 are arranged with adjustable height on a mounting seat 30. Thus, the height of the time domain detection component 21 and / or the spectrum detection component 22 can match the height of the light receiving part 11 of the first light information detection component 10, ensuring that the time domain detection component 21 and / or the spectrum detection component 22 can receive the laser reflected from the light receiving part 11.

[0049] Of course, it is understandable that the first optical information detection element 10 can also be arranged to be height-adjustable, so that the height of the light receiving part 11 of the first optical information detection element 10 matches the height of the time domain detection element 21 and / or the spectrum detection element 22, thereby fully ensuring that the time domain detection element 21 and / or the spectrum detection element 22 can receive the laser reflected from the light receiving part 11.

[0050] Optionally, the laser testing device further includes a height adjustment seat 40 and a telescopic column 50. The height adjustment seat 40 is arranged above the mounting seat 30 and is installed with the laser receiving probe 23 (i.e., the photoelectric probe 231 and / or the jumper probe 232). The telescopic column 50 can be arranged between the mounting seat 30 and the height adjustment seat 40 in a vertically telescopic manner to adjust the height of the height adjustment seat 40 during telescoping, so as to adjust the height of the laser receiving probe 23.

[0051] Therefore, when the telescopic column 50 is extended vertically, the height of the height-adjusting seat 40 increases, so that the laser receiving probe 23 installed on the height-adjusting seat 40 is also correspondingly raised. When the telescopic column 50 is shortened vertically, the height of the height-adjusting seat 40 decreases, so that the height of the laser receiving probe 23 installed on the height-adjusting seat 40 is also correspondingly lowered, thereby the height of the laser receiving probe 23 can be increased or decreased accordingly, so that the height of the laser receiving probe 23 can be adjusted.

[0052] Optionally, the telescopic column 50 includes an outer cylinder 51, an inner cylinder 52 and a locking screw 53. The outer cylinder 51 is provided on one of the mounting seat 30 and the height adjustment seat 40. The inner cylinder 52 is provided on the other of the mounting seat 30 and the height adjustment seat 40 and is relatively movably sleeved in the outer cylinder 51. The locking screw 53 passes through the outer cylinder 51 and abuts against the inner cylinder 52 to lock the inner cylinder 52 in the outer cylinder 51.

[0053] Figure 3 FIG. 5 is a schematic diagram of the structure of a telescopic column 50 according to an embodiment of the present disclosure. Figure 3 The inner column 52 is connected to the mounting seat 30 and is located above the mounting seat 30. The outer cylinder 51 is connected to the height adjustment seat 40 and is located below the height adjustment seat 40, and the inner column 52 is relatively movably sleeved in the outer cylinder 51. The locking screw 53 passes through the outer cylinder 51 and abuts against the inner column 52 to lock the inner column 52 in the outer cylinder 51.

[0054] Figure 4 FIG. 5 is a schematic structural diagram of a telescopic column 50 according to another embodiment of the present disclosure. Figure 4 The outer cylinder 51 is connected to the mounting seat 30 and is located above the mounting seat 30. The inner column 52 is connected to the height adjustment seat 40 and is located below the height adjustment seat 40, and the inner column 52 is relatively movably sleeved in the outer cylinder 51. The locking screw 53 passes through the outer cylinder 51 and abuts against the inner column 52 to lock the inner column 52 in the outer cylinder 51.

[0055] Thus, the inner column 52 moves relatively in the outer cylinder 51, so that when the inner column 52 extends in the outer cylinder 51, the telescopic column 50 can be shortened. And the inner column 52 moves relatively in the outer cylinder 51, so that when the inner column 52 extends in the outer cylinder 51, the telescopic column 50 can be extended.

[0056] In some embodiments of the present disclosure, see Figure 1 and Figure 2The reflected light detection assembly 20, that is, the time domain detection component 21 and / or the spectrum detection component 22 is arranged on a mounting seat 30 in an adjustable direction, and the direction is in the horizontal direction and / or the pitch direction.

[0057] As a specific example, the laser receiving probe 23 (ie, the photoelectric probe 231 and / or the jumper probe 232 ) of the time domain detection element 21 and / or the spectrum detection element 22 is adjustably disposed on a mounting seat 30 .

[0058] Specifically, the adjustable orientation of the laser receiving probe 23 in the horizontal direction can be achieved by rotating the laser receiving probe 23 around the vertical axis. The adjustable orientation of the time domain detection element 21 and / or the spectrum detection element 22 in the pitch direction can be achieved by rotating the laser receiving probe 23 around the horizontal axis.

[0059] Therefore, before or during detection, the orientation of the reflected light detection component 20 can be adjusted to a position where it can receive as much reflected laser light as possible, based on the reflection of laser energy by the first optical information detection element 10, thereby ensuring that the reflected light detection component 20 can receive sufficient laser light during detection and ensuring the detection effect of the reflected light detection component 20.

[0060] Optionally, the first optical information detection component 10 can also be set in an adjustable direction, the direction being the horizontal direction and / or the pitch direction. Specifically, by way of example, the adjustable direction of the first optical information detection component 10 in the horizontal direction can be achieved by rotating the first optical information detection component 10 around the vertical axis. The adjustable direction of the first optical information detection component 10 in the pitch direction can be achieved by rotating the first optical information detection component 10 around the horizontal axis. Thus, before or during detection, the direction of the light receiving portion 11 of the first optical information detection component 10 can be adjusted to a position where the reflected light detection component 20 can receive as much of the reflected laser as possible, based on the reflection of the laser energy by the first optical information detection component 10, thereby ensuring that the reflected light detection component 20 can receive sufficient laser light during detection and ensuring the detection effect of the reflected light detection component 20.

[0061] Optionally, the laser testing device further comprises a direction adjusting member 41 and a fixing screw 42. The direction adjusting member 41 is used to fix the laser receiving probe 23. Optionally, a through fixing hole 4101 is formed in the direction adjusting member 41, and the laser receiving probe 23 can be fixed in the fixing hole 4101. The direction adjusting member 41 is placed above the mounting seat 30. The fixing screw 42 passes through the threaded hole 401 of the height adjusting seat 40 and is connected to the direction adjusting member 41 to fix the direction adjusting member 41.

[0062] Therefore, when adjusting the orientation of the laser receiving probe 23, the fixing screw 42 can be removed first, and then the adjustment member 41 can be rotated by a predetermined angle, so that the orientation of the laser receiving probe 23 in the horizontal direction is changed, and then the fixed screw 42 can be used to fix the rotated laser receiving probe 23 again after the orientation is adjusted.

[0063] Optionally, the direction-adjusting member 41 may also be rotated around a horizontal axis so as to change the orientation of the laser receiving probe 23 fixed to the direction-adjusting member 41 in the pitch direction.

[0064] According to some embodiments of the present disclosure, the laser receiving probe 23 is mounted on the mounting seat 30 in an adjustable position, especially in an adjustable horizontal position, relative to the mounting seat 30. Specifically, the laser receiving probe 23 is mounted on the height adjustment seat 40 in an adjustable horizontal position, so that the horizontal position of the laser receiving probe 23 relative to the mounting seat 30 is adjustable.

[0065] Optionally, there are a plurality of threaded holes 401, and the plurality of threaded holes 401 are horizontally spaced apart on the height adjustment seat 40. Thus, when the fixing screws 42 pass through different threaded holes 401 and fix the direction adjustment member 41, the direction adjustment member 41 is fixed at different horizontal positions, so that the horizontal position of the direction adjustment member 41 is adjustable, thereby making the horizontal position of the laser receiving probe 23 fixed to the direction adjustment member 41 adjustable.

[0066] In some embodiments of the present disclosure, see Figure 1 and Figure 2 The laser testing device further comprises an inserting seat 60. The inserting seat 60 is arranged on the height adjustment seat 40, and the inserting seat 60 forms an inserting slot 601 suitable for inserting the laser emitter 900.

[0067] Therefore, the laser emitter 900 can adjust the height of the height adjustment seat 40 so that the height of the laser emitter 900 in the insertion seat 60 matches the height of the light receiving part 11, so that the light receiving part 11 can receive the laser emitted by the laser emitter 900.

[0068] Optionally, the socket 60 is made of a metal material, such as an iron material. Therefore, during the process of the laser emitter 900 emitting a laser, when the temperature of the laser emitter 900 is high due to operation, the socket 60 can quickly conduct the heat dissipated by the laser emitter 900 to the external environment, thereby achieving the effect of quickly dissipating heat and cooling the laser emitter 900, thereby ensuring that the laser emitter 900 can be at a more suitable working temperature.

[0069] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
