With the development of medical care, there are quite a lot of related medical diagnosis and biochemical tests. Various instruments, especially in recent years, have become more and more important in the health of the oral cavity. The oral diagnostic equipment for detecting the oral state of the human body is widely used in dental and dental clinics of hospitals at all levels.

Traditionally, the detection and diagnosis of oral cancer is mostly carried out by visual inspection by a physician or by a related technique such as a section test. If the doctor's visual inspection technique is used to check the oral cavity, most of the detection devices are needed to assist the doctor to perform more detailed examinations. Most of the current techniques are directly projected onto the patient's target to be examined by ultraviolet light, and the operator observes the reaction through the observation window. However, the current technology must be judged directly by the operator on the spot to be able to store the image data, and the conventional detection device needs to set up the required filter on the observation window, filter the reflected detection light source, and cannot be easily replaced. Replacing the filter and observing the image of the fluorescence reaction of different spectra is therefore quite inconvenient to use. Furthermore, in the conventional oral detecting device, there is no mechanism for providing anti-fogging on the detecting device.
