Oral self-examination has always been difficult. Deep within the teeth, between gaps, and on the chewing surfaces of molars—these areas are hard to see with the naked eye, and ordinary mirrors lack sufficient magnification. Smart dental mirrors have changed this: by connecting to a mobile app, users

Endoscope camera modules have evolved from niche medical tools into widely adopted imaging components across multiple industries. With continuous improvements in CMOS sensor technology, miniaturization, and optical design, these modules now enable visual inspection in environments that are otherwise

I. Introduction: When Inspection Space and Imaging Precision Evolve TogetherIn the fields of industrial pipeline inspection, heavy equipment maintenance, and municipal engineering exploration, an increasingly prominent technical challenge is emerging: the physical scale of inspection targets is grow

IntroductionMost endoscope cameras look straight ahead. Point the tip at what you want to see, and there it is. But what if what you need to inspect is off to the side—like the inside wall of a pipe, a cylinder bore, or a weld seam? That’s where a side-view endoscope camera module comes in. Instead
