What are the precautions for choosing a scientific camera sensor?

The emergence of machine vision systems has greatly increased the automation of production and expanded the scope of research in the field of science. Machine vision can quickly acquire a large amount of information, simple automatic image processing, and easy system integration of information. Therefore, it has been widely used in various fields. In the field of product inspection, quality control, industrial measurement, etc., the machine vision system is mainly based on industrial cameras, while in the fields of biological science, astronomy, and chemical imaging, it is a system led by scientific cameras. The most important part in the machine vision system is the camera, and the most important part of the camera is the sensor. For the field of science , the importance of the scientific camera sensor is self-evident.

Whether it is industrial measurement or scientific research, the choice of machine vision system is critical, especially the choice of scientific camera sensor is the first problem to be solved. After the sensor selection is completed, the matching equipment and solutions can be determined. Therefore, the success of the detection of scientific research projects is largely related to the choice of sensors. So, what are the considerations for choosing a scientific camera sensor ?

The choice of scientific camera sensors depends on stability, dynamic range, responsiveness, sensitivity, cost of the machine vision system, and application requirements.

Stability . The reason why machine vision is favored is that its stability is far higher than artificial vision, which guarantees the effectiveness of scientific research. Therefore, stability is a major influence factor of sensor selection. In addition to the structure, sensor stability is mainly affected by the use environment, that is, scientific camera sensors must have strong environmental adaptability. Then, if you can't reduce the impact of the environment when choosing, you should try to choose the right sensor according to the use environment.

Dynamic range . The dynamic range of the scientific camera sensor determines the quality of the image. The wider the dynamic range, the finer the details of the image. When choosing, you should choose the appropriate dynamic range according to your needs. Don't be small, not too wide. There are different dynamic range sensors available on the market. When it comes to dynamic range, speed is linked to speed, and speed and dynamic range are interrelated, because in order to transmit images more quickly, the sensor needs to quickly form a stable output.

Sensitivity . In general, the higher the sensitivity of a scientific camera sensor , the more favorable it is for signal processing, and therefore the sensitivity is also required. However, the higher the sensitivity, the greater the influence of noise, which easily affects the accuracy of the detection. Therefore, it is also required that the sensor should have a high signal to noise ratio.

In addition, the detection distance, the experimental requirements for the sensor volume, the measurement method is contact or non-contact, the source of the sensor is domestic or imported, and the range of price tolerance is a matter of concern when selecting a scientific camera sensor .
