[0004] In the above case, there is a problem that the adjustment parts are worn out due to long-term operation, which affects the adjustment accuracy. Therefore, a dispersive multifunctional Hadamard transform microscopic imaging spectrometer is proposed to solve the problem. Summary of the invention

[0005] In order to overcome the problem that the adjustment parts are worn out after long-term operation, which affects the adjustment accuracy, the purpose of the present invention is to provide a dispersive multifunctional Hadamard transform microscopic imaging spectrometer, which has the function of reducing wear and maintaining stable operation.

[0006] The present invention adopts the following technical scheme to achieve the technical purpose: a dispersive multifunctional Hadamard transform microscopic imaging spectrometer, comprising a base, the top of the base is fixedly connected to a light adjustment device, a Y-direction adjuster and a grip wall, the side of the Y-direction adjuster is slidably connected to the X-direction adjuster, the top of the X-direction adjuster is slidably connected to the Z-direction adjuster, the top of the Z-direction adjuster is fixedly connected to the stage, the top of the grip wall is clamped to the imaging stage, the top of the imaging stage is fixedly connected to the eyepiece, the bottom of the imaging stage is rotatably connected to the objective lens, and a stabilizing mechanism is arranged on one side where the X-direction adjuster, the Y-direction adjuster and the Z-direction adjuster are connected.

[0007] As an optimization, the stabilizing mechanism includes a slide groove provided on a connecting side of the X-axis regulator, the Y-axis regulator and the Z-axis regulator, the interior of the slide groove is slidably connected to a slider, a power device is fixedly connected between the slider and the slide groove, an inner cavity is provided inside the slider, a controller is fixedly installed inside the inner cavity, and control blocks are movably installed on both sides of the controller;

[0008] An installation groove is provided on the outer side of the sliding block, a stabilizing wheel is movably installed inside the installation groove, and two sides of the stabilizing wheel are movably connected to a control rod extending into the inner cavity.

[0009] As an optimization, the X-axis regulator, the Y-axis regulator and the Z-axis regulator are connected via a sliding groove and a sliding block.

[0010] As an optimization, the control block is divided into a protruding state and a standby state, and the two groups of states are cross-distributed, the control rod is in contact with the control block, and the two are adsorbed by magnetic force.

[0011] As an optimization, the installation groove is divided into a push-out shape and a storage shape. The push-out shape installation groove corresponds to the protruding state control block, and the storage shape installation groove corresponds to the standby state control block. The stabilizing wheel in the push-out shape installation groove is in close contact with the inner wall of the slide groove.

[0012] As an optimization, a pressure sensing module is installed on the surface of the control block, and a change module is arranged inside the controller;

[0013] A pressure sensing module, used to sense the pressure between the control block and the control rod;

[0014] The change module is used to bind the adjacent protruding state control block and the standby state control block. When the pressure between the protruding state control block and the control rod is insufficient, the standby state control block is pushed out, and the corresponding control rod pushes out the stabilizing wheel.

[0015] As an optimization, an aperture adjustment module is fixedly installed at the bottom of the objective lens, and a laser positioning module, a coordinate establishment module, and an image processing module are arranged in the imaging platform;

[0019] The image processing module is used to process the data of the laser positioning module and the coordinate establishment module to produce a complete map.

[0020] The present invention has the following beneficial effects:

[0021] 1. The dispersion-type multifunctional Hadamard transform microscopic imaging spectrometer sets a stabilizing wheel between the slider and the slide groove, thereby changing the sliding friction into rolling friction, reducing the wear between the slider and the slide groove, and making the X-direction regulator, the Y-direction regulator and the Z-direction regulator more stable under long-term working conditions.

[0022] 2. The dispersion-type multifunctional Hadamard transform microscopic imaging spectrometer controls the alternation of the stabilizing wheels through a controller. When the stabilizing wheels in the push-out shaped mounting groove are excessively worn after working for a long time, the diameter of the stabilizing wheels becomes smaller, which causes the control rod to exert insufficient pressure on the convex state control block. The pressure sensing module sends a signal, and the change module starts the corresponding standby state control block. The control block pushes out the stabilizing wheel in the storage shaped mounting groove through the control rod to replace the excessively worn stabilizing wheel, thereby extending the service life of the regulator and making it work more stably.

[0023] 3. The dispersion-type multifunctional Hadamard transform microscopic imaging spectrometer can adjust the size of the display aperture by observing the state, so as to prevent the light scattered from the periphery of the spectrum from affecting the clarity of the spectrum. At the same time, it can avoid the distraction of the observer, thus improving the work efficiency to a certain extent.

[0024] 4. The dispersive multifunctional Hadamard transform microscopic imaging spectrometer uses a beam of light to determine a point on the spectrum and always keeps this point in the middle of the observation field of view. This facilitates the adjustment of the spectrum position and allows for rapid zooming in and out without losing the observation target, thus achieving the freedom of rapid capture.

[0025] 5. The dispersive multifunctional Hadamard transform microscopic imaging spectrometer ensures the accuracy of the position of the observed spectrum on the complete spectrum and the accuracy of the detailed display on the complete spectrum by continuously establishing, identifying and analyzing coordinate information during the adjustment process, thereby preventing data errors or equipment wear and tear from causing missing spectral imaging.

DETAILED DESCRIPTION

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figure 1-4 The dispersive multifunctional Hadamard transform microscopic imaging spectrometer comprises a base 1, the top of the base 1 is fixedly connected to a light adjusting device 2, a Y-axis adjuster 3 and a grip wall 7, the side of the Y-axis adjuster 3 is slidably connected to an X-axis adjuster 4, the top of the X-axis adjuster 4 is slidably connected to a Z-axis adjuster 5, the top of the Z-axis adjuster 5 is fixedly connected to a stage 6, the top of the grip wall 7 is clamped to an imaging stage 8, the top of the imaging stage 8 is fixedly connected to an eyepiece 9, the bottom of the imaging stage 8 is rotatably connected to an objective lens 10, and a stabilizing mechanism 11 is arranged on one side where the X-axis adjuster 4, the Y-axis adjuster 3 and the Z-axis adjuster 5 are connected.

[0034] The stabilizing mechanism 11 includes a slide groove 111 provided on a connecting surface of the X-axis regulator 4, the Y-axis regulator 3 and the Z-axis regulator 5, a slider 112 is slidably connected inside the slide groove 111, a power device 113 is fixedly connected between the slider 112 and the slide groove 111, an inner cavity 114 is provided inside the slider 112, a controller 115 is fixedly installed inside the inner cavity 114, and control blocks 116 are movably installed on both sides of the controller 115;

[0035] An installation groove 117 is formed on the outer side of the sliding block 112 , and a stabilizing wheel 118 is movably installed inside the installation groove 117 . Both sides of the stabilizing wheel 118 are movably connected to a control rod 119 extending into the inner cavity 114 .

[0036] The X-axis regulator 4, the Y-axis regulator 3 and the Z-axis regulator 5 are connected via a slide groove 111 and a slider 112, and the X-axis regulator 4, the Y-axis regulator 3 and the Z-axis regulator 5 control the stage 6 to move freely in the X, Y and Z directions.

[0037] The control block 116 is divided into a protruding state and a standby state, and the two states are cross-distributed. The control rod 119 is in contact with the control block 116, and the two are attracted by magnetic force.

[0038] The mounting groove 117 is divided into a push-out shape and a storage shape. The push-out shape mounting groove 117 corresponds to the protruding state control block 116 , and the storage shape mounting groove 117 corresponds to the standby state control block 116 . The stabilizing wheel 118 in the push-out shape mounting groove 117 is in close contact with the inner wall of the slide groove 111 .

[0039] The surface of the control block 116 is provided with a pressure sensing module, and the controller 115 is provided with a change module inside;

[0040] A pressure sensing module, used to sense the pressure between the control block 116 and the control rod 119;

[0041] The changing module is used to bind the adjacent protruding state control block 116 and the standby state control block 116. When the pressure between the protruding state control block 116 and the control rod 119 is insufficient, the standby state control block 116 is pushed out, and the corresponding control rod 119 pushes out the stabilizing wheel 118.

[0042] By arranging a stabilizing wheel 118 between the slider 112 and the slide groove 111, sliding friction is changed into rolling friction, thereby reducing the wear between the slider 112 and the slide groove 111, making the X-direction regulator 4, the Y-direction regulator 3 and the Z-direction regulator 5 more stable under long-term working conditions.

[0043] The alternation of the stabilizing wheel 118 is controlled by the controller 115. When the stabilizing wheel 118 in the push-out shape mounting groove 117 is excessively worn after working for a long time, the diameter of the stabilizing wheel 118 becomes smaller, which causes the control rod 119 to exert insufficient pressure on the protruding state control block 116. The pressure sensing module sends a signal, and the change module starts the corresponding standby state control block 116. The control block 116 pushes out the stabilizing wheel 118 in the storage shape mounting groove 117 through the control rod 119 to replace the excessively worn stabilizing wheel 118, thereby extending the service life of the regulator and making it work more stably.

[0045] See also Figure 1The dispersive multifunctional Hadamard transform microscopic imaging spectrometer comprises a base 1, the top of the base 1 is fixedly connected to a light adjusting device 2, a Y-axis adjuster 3 and a grip wall 7, the side of the Y-axis adjuster 3 is slidably connected to an X-axis adjuster 4, the top of the X-axis adjuster 4 is slidably connected to a Z-axis adjuster 5, the top of the Z-axis adjuster 5 is fixedly connected to a stage 6, the top of the grip wall 7 is clamped to an imaging stage 8, the top of the imaging stage 8 is fixedly connected to an eyepiece 9, and the bottom of the imaging stage 8 is rotatably connected to an objective lens 10.

[0046] An aperture adjustment module is fixedly installed at the bottom of the objective lens 10, and a laser positioning module, a coordinate establishment module, and an image processing module are arranged in the imaging platform 8;

[0047] Aperture adjustment module, used to control the size of the spectrum entering through the objective lens;

[0048] By adjusting the size of the display aperture according to the observation status, the scattered light from the periphery of the spectrum can be prevented from affecting the clarity of the spectrum. At the same time, the observer's attention can be avoided from being distracted, thus improving work efficiency to a certain extent.

[0049] The laser positioning module is used to determine a point on the map through a beam of light and always keep this point in the middle of the observation field;

[0050] This makes it convenient to adjust the position of the map, and allows for quick zooming in and out without losing the observed target, thus enabling the freedom of quick capture.

[0051] A coordinate setting module is used to randomly set coordinates on the spectrum and record the spectral pattern at the coordinates as a reference for adjusting the position of the spectrum;

[0052] When such a spectrum is large and needs to be constantly adjusted for observation, the coordinate information is continuously established, identified, and analyzed during the adjustment process to ensure the accuracy of the position of the observed spectrum on the complete spectrum and the accuracy of the details displayed on the complete spectrum, thereby preventing data errors or equipment wear and tear from resulting in missing spectral imaging.

[0053] Image processing module, used to process the data of laser positioning module and coordinate establishment module to produce complete maps;
