[0002] The pixel points of the image sensor in a digital microscope are fixed. During the microscopic imaging process, the larger the magnification, the smaller the field of view of the digital camera. When using a 40x magnifying glass, the area captured by the digital camera is approximately in the range of 0.2 mm wide and 0.3 mm long. If the height of the accommodation cavity for the detection chip is 0.2 mm, the volume captured in one picture is 0.012 cubic millimeters. In most detection scenarios, there are requirements for the sample volume of the detection object. Therefore, many pictures need to be taken at different positions or different focal planes. Many times, the number of pictures that need to be taken exceeds 1000, which takes a long time and seriously affects the timeliness of detection. Many times, for the target objects in the detection sample, such as cells, bacteria, etc., there are requirements for the detection duration.
