In fig. 1, the AR display device body 1 is an AR glasses device, and in practical application, the AR display device body 1 of the augmented reality display device is not limited to the AR glasses device, and may also be similar to an AR helmet or other similar AR head-mounted devices, which is not specifically limited in this application.
In addition, the fluid velocity measurement device 2 in the augmented reality display device in this embodiment is a device capable of measuring both the gas velocity and the liquid velocity.
In an embodiment of a specific application of an augmented reality display device, the augmented reality display device may be goggles, such as mountain-climbing goggles, which may be worn by a wearer during riding, mountain climbing.
The mountaineering goggles worn by the wearer during riding can detect the wind speed in the environment, so that the environmental resistance overcome by the wearer is indirectly reflected, and the amount of exercise of the wearer is more accurately reflected.
If the wearer is in mountaineering, especially in severe environments such as snowclimbing, the goggles with the AR display function can display wind speed information to the user in time, even the fluid speed measuring device on the goggles can be a device capable of detecting wind speeds in different directions, so that the environment information is provided for the wearer in time, more comprehensive information is provided for activities such as snowclimbing of the wearer, and the wearer is facilitated to make safety measures in time.

In practical applications, the augmented reality display device having a function of measuring a fluid flow rate may be configured to only configure the fluid velocity measuring device 2 capable of measuring a wind speed, for example, configure an anemometer on the augmented reality display device, or configure a fluid velocity measuring device, for example, a water velocity meter, for measuring a water velocity, for a specific application scenario, for example, measuring a wind speed in a mountain. Certainly, the fluid speed measuring device 2 capable of measuring both water speed and wind speed can be selectively arranged, so that diversified applications of the augmented reality display device are realized, for example, a laser doppler speed measuring device can be adopted.
Further, considering that when the flow rate of the fluid in the environment is detected, the flow rate of the fluid relative to the wearer can be detected, and when the wearer uses the augmented reality display device, if the wearer is in a motion state, it is obvious that there is a large difference between the measured flow rate of the fluid relative to the wearer and the actual flow rate of the fluid, therefore, in an alternative embodiment of the present application, the fluid speed measuring device in the augmented reality display device may include two parts, one part is a first speed measuring device for detecting the motion speed of the wearer, and the other part is a second speed measuring device for detecting the flow speed of the fluid relative to the wearer.

As for the second velocimeter, as mentioned above, it may be an anemometer, a water velocimeter, or a laser doppler velocimeter.
Based on any of the above embodiments, the fluid velocity measuring device will be further described in detail below by taking a laser doppler velocity measuring device as an example.
As shown in fig. 2, fig. 2 is a schematic perspective view of a laser doppler velocity measurement device provided in an embodiment of the present application, where the laser doppler velocity measurement device includes:
a light source part 22 for generating two beams of coherent light, a photoelectric detector 23 for detecting optical signals, and a fluid channel 24 for accommodating fluid in the environment to flow through;
the two beams of coherent light output by the light source 22 may interfere with each other to form an interference measurement interval, and the interference measurement interval is located in the fluid channel 24.
The laser doppler technique measures the velocity of a particle to be measured by using laser as a means by using the doppler principle. The laser Doppler velocity measurement technology judges the flow velocity of fluid and gas by detecting solid particles in the fluid or the gas, the Doppler frequency and the velocity are in a linear relation, and the Doppler frequency and the velocity are unrelated to the temperature and the pressure of a measurement point, so that the measurement precision is improved to a great extent.
The basic working principle of the laser Doppler technology is that two coherent laser beams interfere with each other in space to form an interference interval, and a detector is arranged, wherein a light source of the coherent laser beams and the detector are respectively positioned at two sides of the interference interval. When the magnetic particles pass through the interferometric measuring interval, the detector can detect corresponding optical signals, and the speed of the detected particles can be determined based on the optical signals.
Therefore, as shown in fig. 2, the laser doppler velocity measuring device is generally disposed in a loop-shaped housing 21, a through hole in the middle of the loop-shaped housing 21 is a fluid channel 24 for fluid to flow through, a light source 22 and a photodetector 23 capable of emitting two coherent laser beams are disposed on two sides of the fluid channel 24, two hole walls of the through hole in the middle of the loop-shaped housing 24, which are close to the light source 22 and the photodetector 23, are transparent hole walls, and a direction indicated by an arrow in fig. 2 is a flowing direction of the fluid passing through the loop-shaped housing 21.
In fig. 2, in order to avoid the lines from interfering with each other, two different dotted lines are shown in fig. 2 to respectively represent the invisible edge profile of the clip-shaped housing and the invisible profile of the components enclosed inside the comet housing.
Further, the wall of the through-hole-shaped fluid channel in the laser doppler velocity measurement device packaged by the rectangular housing 21 has a certain influence on the flow of the fluid, so that in the practical application process, the light source 22 and the photodetector 23 can be packaged by using mutually independent housings, so that the fluid channel belongs to an open channel.
As shown in fig. 3, fig. 3 is a schematic view of an optical path structure of a light source unit according to an embodiment of the present application, where the light source unit 22 may include:
a laser light source 221, a beam splitter 223, a mirror 224, and a condenser lens 225;

the reflector 224 is disposed on the reflection outgoing light path or the transmission outgoing light path of the beam splitter 223, and is configured to reflect one of the two transmitted light beams and the reflected light beam, so that the two light beams enter the condenser lens 225 in parallel, and are condensed and interfered by the condenser lens 225.
As shown in fig. 3, the laser beam output by the laser source 221 in fig. 3 is reflected twice at 45 degrees by the reflecting element 222, and the laser beam is translated in parallel by the distance h, where the reflecting element 222 may be two mutually parallel reflectors or an oblique prism; the laser beam outputted by the light reflecting element 222 is incident to the beam splitter 223 and is split into a beam of reflected light and a beam of transmitted light which are transmitted perpendicularly to each other by the beam splitter 223; a reflecting mirror 224 is disposed on the optical path of the reflected light, the reflecting mirror 224 deflects the transmission direction of the reflected light by 90 degrees, so that the reflected light and the transmitted light are incident to a condenser lens 225 in parallel, wherein the distance between the reflecting mirror 224 and the beam splitter 223 is 2h, and the laser light source is located on the optical axis of the condenser lens 225, so that the reflected light and the transmitted light are incident to the condenser lens 225 in parallel and symmetrically at a height h from the optical axis, and further the reflected light and the transmitted light which are parallel to each other interfere with each other in the space behind the condenser lens 225 to form an interference measurement interval.
It is understood that, as for the light reflecting element 222, the main function is to modulate the position of the light path in space, in practical applications, the light reflecting element 22 is not necessarily required to be disposed, and the light beam output by the laser light source 221 is directly split by the beam splitter 223 to implement the technical solution of the present application. In addition, the reflecting mirror 224 is to modulate the transmission direction of the reflected light to be parallel to the transmission light, and in the practical application process, the reflecting mirror 224 may also maintain the straight propagation of the reflected light and deflect the propagation direction of the transmission light by 90 degrees, so as to realize the parallel transmission of the reflected light and the transmission light, and the distance between the reflected light and the transmission light is not necessarily required, so long as the reflected light and the transmission light are ensured to be parallel and symmetrically incident to the condenser lens 225.
As the laser light source 221 in this embodiment, a VCSEL light source, an EEL light source, or the like having a strong light condensing ability may be used.
For the photo detector 23 in this embodiment a PMT detector or other detector capable of detecting the velocity of the moving particles in the interferometric measuring region may be used.
In practical application, for more accurate fluid data that surveys, can set up a plurality of these laser doppler speed measuring devices in with augmented reality display device, for example, can set up respectively and measure the fluid velocity of flow in the three not equidirectional of direction from top to bottom, left and right directions and fore-and-aft direction, and then promote the comprehensiveness that augmented reality display device measured data.
