Description

TECHNICAL FIELD

[0001] The present application relates to the field of microscopes, in particular to a short light path digital microscope for optimizing human-computer interaction process and a control method thereof. BACKGROUND

[0002] In the prior art, the light source of a digital biological microscope generally adopts an LED light source. The light emitted by the LED light source is converged into a condenser lens, focused in the condenser lens, and finally focused on an object platform. The light passes through the observed object, is refracted by an objective lens, enters a binocular, and is restored by a microscope binocular head to form an image for a user to observe. The user adjusts a focusing hand wheel to control the height of the object platform, so that the object and the focal point of the condenser lens are focused on the focal point of the objective lens.

[0003] The power of the LED light source of the digital biological microscope in the prior art is about 2-3W, which is relatively high.

[0004] Moreover, the structure of the biological microscope in the prior art needs a higher space because the condenser lens and the condenser lens are needed at the lower part, so that the overall height of the microscope is high, the eye point for observation is high, and therefore the display components such as the display screen are not in line with the habits of the operators if they are arranged on the two sides, and it is inconvenient to use for long-term observation with the head on the side. If the display screen is arranged at the upper end, the operator needs to look up to use, which is easy to cause discomfort of the neck and deviation of the observation angle. Similarly, because the condenser lens and the condenser lens are arranged at the bottom end, the focusing hand wheel needs to be staggered with the above-mentioned components and can only be arranged at the rear, which is inconvenient to use. The condenser lens and the condenser lens are optical components and need optical assemblies, which have a certain difficulty in processing and adjustment and are high in cost. Because the optical path is long and more optical glass pieces are passed through, the light loss is also large, and a large amount of energy is consumed to achieve the brightness for use. There is no more space for integrating multimedia or computer parts in the structure.

[0005] CN210923497U is a newly applied patent, which has a complex structure and uses a conical lens, a compound eye lens, and two pieces of optical glass. It does not have a variable diaphragm structure and cannot meet the control of depth of field and clarity. According to the principle diagram, it is inferred that the illumination effect is not good and cannot meet the use requirements of general microscopes, not to mention special requirements for special machines.

The housing includes an upper housing 23, a lower housing 20, and a bottom cover 29. The condenser lens 21 is fixed to the upper end of the upper housing 23 by a condenser lens 21 mount. The variable aperture 24 is inserted between the lower end of the upper housing 23 and the upper end of the lower housing 20. The conical lens 26 is placed below the variable aperture 24.

The variable aperture 24 is equipped with an aperture lever 25, which extends out of the housing. The aperture lever 25 is used to adjust the variable aperture 24 to adapt to different observation needs.

[0028] In this embodiment, the ratio of the distance from the LED lamp 27 to the upper surface of the conical lens 26, the distance from the upper surface of the conical lens 26 to the upper surface of the variable aperture 24, the distance from the variable aperture 24 to the upper surface of the condenser glass 21, and the distance from the condenser glass 21 to the upper surface of the stage is 26:(5~7):(65~69):1.

The camera assembly 9 comprises a camera and a camera adapter lens 6, which is installed on the front side of the camera.

[0037] More specifically, the computer component 13 is connected with the lens body 12 by screwing, the screwing connector inside the lens body 12 is connected with the extension cylinder 8 by screwing, the camera adapter lens seat 7 is connected with the five-sided prism seat 4 by screwing, the five-sided prism 5 is connected with the five-sided prism seat 4 by screwing and gluing, the five-sided prism seat 4 is connected with the horizontal arm 10 by screwing, and the binocular interface 3 is connected with the five-sided prism seat 4 by screwing. The camera adapter lens seat 7 is connected with the five-sided prism seat 4 by screwing, the camera component 9 is connected with the extension cylinder 8 by screwing, and the extension cylinder 8 is connected with the camera adapter lens seat 7 by screwing. The horizontal arm 10 is connected with the lens body 12 by screwing, and the focusing base 16 is connected with the lens body 12 by screwing. The object platform component 14 and the light source structure 15 are connected by screwing, the light source structure 15 is connected with the up-and-down bracket 17 by the annular dovetail interface, and the up-and-down bracket 17 is connected with the rack 18 by screwing.

[0039] When the focusing hand wheel 191 is rotated, the rack 18 is driven to move up and down, thereby driving the up-and-down bracket 17, the object platform component 14 and the light source structure 15 to move up and down, and the focusing action is completed.

[0040] The short light path digital microscope for optimizing the human-computer interaction process in the embodiment has the specific control method, which includes the following steps: Step S1, placing the observation sample slide above the object platform component; Step S2, selecting the appropriate objective lens 112, and rotating the objective lens converter 111 to rotate the objective lens 112 to the working position; Step S3, rotating the focusing hand wheel 19 to control the object platform component 14 to ascend and descend, so that the observation sample is located at the focal point position; Step S4, adjusting the variable diaphragm 24 to the position corresponding to the magnification of the objective lens 112, and adjusting the brightness to an appropriate degree; Step S5, adjusting the picture position according to the image presented by the display screen 1, and controlling the picture zooming as needed, to specifically observe the image and apply it to other multimedia demand scenarios.

[0041] It should be noted that in step S4, the brightness adjustment can be realized by using the physical brightness adjustment knob or other physical adjustment structure in the prior art, or by setting the corresponding brightness adjustment function through the computer component 13.

[0042] Effect example 1 The observation is performed by using the short light path digital microscope for optimizing the human-computer interaction process in the above embodiment 1, and the image is as shown in (a) of Figure 4 At the same time, the comparative observation is performed by using the ordinary biological microscope, and the image is as shown inFigure 4 As shown in (b) of the diagram.

[0044] As can be seen, the short-path digital microscope of the present invention, which is designed to optimize the human-computer interaction process, can still perform imaging clearly and maintain the required brightness under low energy consumption conditions.

[0045] like Figure 5 As shown, the optical path design principle of the short-path digital microscope for optimizing the human-computer interaction process disclosed in this invention is as follows: Light emitted from LED 27 passes through the conical lens 26, then is collimated and focused onto the object platform 14 by the condenser lens 21. Next, after passing through the object, the light is refracted by the objective lens 112, restored by the tube diameter 30, and then split and redirected by the pentagonal prism 5. One beam is corrected by the camera adapter lens 6 and falls onto the camera assembly 9, while the other beam leads to the binocular interface 3. This microscope, because it allows for the simultaneous installation of binocular lenses at the binocular interface 3, enables multi-mode observation.
