On the other hand, the preset observation range represents a range of the sample band 3 irradiated by the light source 10 and observed by the microscopic device 11, and the preset observation range is located within the first region.

The CCD sensor is a new type of photoelectric conversion device that can store signal charges generated by light.

The photoelectric conversion optical fiber laser mainly comprises a photosensitive unit, an input structure, an output structure and the like, has the functions of photoelectric conversion, information storage, time delay and the like, has high integration level, low power consumption and low running cost, and has been widely applied to the fields of camera shooting, signal processing, storage and the like.

In a preferred embodiment, the image sensor 12 is a CMOS sensor.

CCD and CMOS sensors are two types of image sensors 12 that are commonly used, both of which convert an image into digital data by photoelectric conversion using photodiodes, and the main difference is the manner of transferring the digital data.

The main advantage of CMOS over CCD is that it is very power efficient, CMOS circuits have little static power consumption, and only when the circuit is turned on does power consumption, which makes CMOS power consumption only about 1/3 for a normal CCD. In addition, the image data scanning methods of CMOS and CCD are very different. For example, if the resolution is 300 ten thousand pixels, then the CCD sensor can scan 300 thousand charges in succession, the method of scanning is very simple as if a bucket were passed from one person to another, and the signal can only be amplified after the last data scan is completed. Each pixel of a CMOS sensor has an amplifier that converts charge into an electronic signal. Thus, the CMOS sensor can amplify signals on a per pixel basis, and any inefficient transfer operations can be saved by this method, so that fast data scanning can be performed with a small amount of power consumption, and noise is reduced. The operating costs of the device can thus be further reduced.

As can be seen from the above, in the present embodiment, the automatic online observation device for air-borne pollen has at least the following technical effects compared with the prior art: the operation difficulty and the working strength of observers are reduced, the cost is reduced, the observation efficiency and the accuracy are improved, and the user experience is improved.
