BT-1800 Dynamic Image particle analysis system is a built-in distributed systems and high-speed camera loop image size and morphology analysis system. It is a micro-imaging technology, automatic control technology, image processing technology combined with the product. As long as the sample into the circulatory system, the system will automatically cycle, distributed, continuous shooting particle images, and particle image processing and analysis. The system has a visual image, accurate, and automatic recognition, statistical, quantification and other characteristics, not only can be used to observe the particle morphology, particle size distribution can also be obtained, aspect ratio and circularity, etc., for scientific research, production and add fields A new particle size measurement means. 

 First, the performance index: 
 1. Test range :1-3000μm. 
 2. Maximum magnification: 1600 times. 
 3. Maximum resolution: 0.1μm. 
 : Germany AVT high-speed cameras, imaging speed of 120 frames / sec. 
 5. Repeatability error: 3% (sample of factors does not contain the error.) 
 6. Results Distribution of species: particle size distribution, aspect ratio distribution, circularity distribution. 
 7. Interface: Control Interface for the USB, the interface mode for the 1394 image. 
 8. Circular pool volume: 300ml. 
 9. Circulation flow rate: 500ml / min. 

 Second, the image analysis principle: 
 1. Image particle analysis system works: for each particle by the number of pixels contained in the statistics, the so calculated circle area of each particle, resulting in area of a circle diameter of such particles, such as volume diameter and aspect ratio so the ball to obtain information such as particle size distribution. 
 2. Calibration method: the specific standard scales microscope images filmed 100μm distance by calculating the number of pixels occupied by a single pixel to calibrate the area, and then the share of each particle image to calculate the number of pixels the size of particles. 

 Main technical characteristics 
 1. Unique automatic circulation dispersion system: BT-1800 system, including automatic cycle scattered ultrasonic dispersion, mixer, circulating pump, imaging windows, and automatic water and drainage systems. Flow in the sample particle image continuous shooting mode, to overcome the static image analysis system cumbersome and representative sample of poor shortcomings. 
 2. Multiple images automatically processing functions: high-speed camera in continuous shooting mode particle flow particle image hundreds of sites, and automatically stores the captured images to your computer. After shooting the software will automatically handle these images, automatic segmentation of particles of different sizes will be used to distinguish between different colors, and then get size distribution. 
 3. High-speed CCD camera: BT-1800 using the German imports of high-speed camera, recording speed of 120 frames / sec, ensuring state of the particle in motion without smearing the image, the image effect of the dynamic and static the same effect. 
 4. AF system: BT-1800 precision stepper motor installed on the focal length adjusting device, with the sharpness of the image recognition software to achieve the auto-focus, to ensure that all have good and consistent image clarity.
