1. Working mode: 360-degree rotary scanning and microscopic photo collection. The whole machine is directly driven by notebook or flat USB 3.0 interface. There is no need for external control box or power supply, and external charging treasure can extend the working time of notebook for more than 10 hours;
 
2. Photographing light source: independent white light, ultraviolet light, red light and green light source, software controls the switching of light source, the type and intensity of light source can be programmatically adjusted, and the type and intensity value of light source can be automatically retrieved and saved;
 
3. Scanning light source: independent white light, ultraviolet light, red light and green light, and the switching of light source is controlled by software;
 
4. Photo image parameters: the imaging range is 50mm*40mm, the resolution is 4800DPI, and the photo speed is not less than 1 second;
 
5. Scanning image parameters: the scanning range is 22cm*21cm, the resolutions are 300DPI, 600DPI and 1200DPI, and the scanning speed of 360 degrees at 1200DPI resolution does not exceed 15 seconds;
 
6. Extension rod: stainless steel, using segmented link mode, each section is 20cm long, with millimeter scale, and the positioning hole can lock the depth infinitely;
 
7. Control software: The control system scans and photographs, and has the real-time correction function of lens distortion and color balance; (The two-dimensional code automatic identification function is added in the later stage, which can automatically identify the two-dimensional code information on the root canal for naming the root image);
 
8. Temperature water inlet module: detect the root canal temperature, detect whether the system is soaked, and if it is soaked, give an alarm prompt and cut off power protection;
 
9. The digital earth magnetic field azimuth module can calibrate the earth magnetic field azimuth corresponding to the photographed image in real time, which is convenient for long-term dynamic tracking and positioning;
