Embedded photomicroscopic hyperspectral imaging system

This creative department is related to the spectral imaging system; in particular, it is an embedded photomicroscopic hyperspectral imaging system.

The hyperspectral photography system integrates two systems, such as spectral analysis and image analysis, to obtain the spectral data and image data of the object to be tested in a non-destructive manner, and then perform qualitative and quantitative analysis through the above data.

Among them, the detection technology of hyperspectral photography system has been widely used in the fields of food science, medicine and biology, for example: it can help the quality control of agricultural products and classification; detect whether the appearance of agricultural products is damaged; Residue; detecting the sweetness of agricultural products, etc. Alternatively, the number of microorganisms on the surface of the meat can be detected to analyze the number of bacteria in the meat.

In the Juguan detection system, a hyperspectral camera is mounted on an adjustment bracket, and is matched with a storage platform, wherein the storage platform is placed with a side object. When the spectral image of the to-be-side object is to be taken by the hyperspectral camera, the relative movement of the adjustment bracket and the storage platform is realized by driving the adjustment bracket or the movement of the storage platform by a stepping motor, that is, A relative movement between the hyperspectral camera and the to-be-side object is achieved, by which a strip or a line scan is performed and the spectrum and image data of each part of the object to be tested are taken.

In addition, in the microscopic detection system, since the size of the object to be detected is very small, for example, in the measurement of the cell structure by a microscope, the size is almost in the order of micrometers or even nanometers, regardless of the moving hyperspectral camera. Perform strip or line scan without moving the object to be tested, or Carrying a strip or line scan in such a manner that the object to be tested is moved without moving the hyperspectral camera, and the relative movement of the moving distance is controlled by the driving motor to control the hyperspectral camera or the movement of the object to be tested, resulting in relative movement The amplitude is too large, causing problems such as incomplete image capture, image distortion, and the like. In particular, when an oil-mirror objective lens is used, the object to be tested is immersed in the pine oil, and it is impossible to take the image by a relative movement mechanism.

Therefore, in the prior art, a fine adjustment lens is additionally added between the hyperspectral camera and the image output end of the microscopic imaging of the object to be tested, thereby realizing the hyperspectral camera only by adjusting the position of the fine adjustment lens. The relative movement with the microscopic imaging of the object under test enables the hyperspectral camera to capture the spectrum and image of each part of the object to be tested step by step.

However, the conventional hyperspectral camera and the fine-tuning lens and the microscope are usually connected in a direct fixed manner, and the components are relatively fine in structure, and the relative positions of each other are required to be highly accurate in assembly or disassembly. The opposite. Therefore, when the user wants to exchange or replace the microscopic detection system with the hyperspectral camera in the macroscopic detection system; or when the microscopic detection system wants to replace different hyperspectral cameras (such as cameras of different specifications and different frequency bands) In the assembly/disassembly of the hyperspectral camera of the microscopic detection system, the loading and unloading requires high precision and has the problem of inconvenient assembly.

In view of this, the purpose of this creation is to provide an embedded photomicroscopic hyperspectral imaging system, which is easy to assemble when the hyperspectral camera is replaced between the giant observation system and the microscopic detection system.

In order to achieve the above object, the embedded photomicroscopic hyperspectral imaging system provided by the present invention is optionally disposed in a box or disposed on a bracket, and the bracket is moved relative to an object to be tested; Wherein, the box body has a first fitting portion; the embedded microscope microscopic hyperspectral photography system The system includes: a relay module and a hyperspectral camera module. The relay lens module is configured to pass an image beam; the hyperspectral camera module is disposed on an optical axis of the relay module to receive the image beam passing through the relay module, and Obtaining a spectral data and an image data according to the received image beam, the hyperspectral camera module has a second fitting portion and a joint portion; wherein the hyperspectral camera module passes through the second fitting portion The detachment method is fitted to the first fitting portion of the casing to be located in the casing, or is detachably connected to the bracket through the joint portion.

In order to achieve the above objectives, the present invention further provides an embedded photomicroscopic hyperspectral imaging system comprising a box, a relay module and a hyperspectral camera module. The box body includes a side plate having an entrance port communicating with the inside of the box body, and the box body has a first fitting portion; the relay mirror module is disposed in the box body, the relay mirror module An image beam passes through, and an optical axis of the relay lens module corresponds to an optical port; the hyperspectral camera module is disposed in the box corresponding to an optical axis of the photo mirror module, the hyperspectral camera The module acquires a spectral data and an image data according to the received image beam, and the hyperspectral camera module has a second fitting portion; wherein the hyperspectral camera module passes through the second fitting portion The detachment is connected to the first fitting portion.

In particular, in the microscopic detection system, the assembly precision is low, the loading and unloading means is simple, and the dual functions of assembly and precision positioning are combined.

In addition, if there is a need to use a plurality of different frequency band hyperspectral cameras, only one box 10 can be used, which is used separately with different hyperspectral cameras, and has a multi-purpose machine and cost-saving effect.

In addition, if the projection distance between the slit 34a of the hyperspectral camera module 30 and the relay mirror 24 needs to be adjusted, the adjustment plate 18 is passed through three long slots 18b by three screws (not shown). Corresponding to the screw holes 11a locked in the base 11, and the long slots 18b are designed in a long strip shape, so there are still some tolerances for pre-adjustment adjustment, in other words, the adjustment board 18 It is movably disposed on the base 11. Therefore, when the projection distance is to be adjusted, only the screws of the fixed adjustment plate 18 need to be loosened, and the front and rear focusing strokes can be used after adjusting the direction of the long groove 18b. To drive its projection distance.
