1. Introduction: When Probe Diameter Becomes the Critical FactorIn industrial pipeline inspections, automotive maintenance, and equipment servicing, one often overlooked but crucial parameter is probe diameter. When inspection channels narrow from above 5mm to below 5mm, most standard endoscope modu

IntroductionWhen a doctor needs to see inside a patient’s body without a large incision, they use an endoscope. At the heart of that endoscope is a camera system. A medical endoscope camera system is a complete imaging solution for diagnostic and surgical procedures. It combines a miniature camera,

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

1. Introduction: When Observation Direction Becomes a BottleneckIn industrial inspection, medical aesthetics instruments, and educational labs, a common technical challenge arises: the target of interest is often located on pipe sidewalls, narrow gaps, or hard-to-reach areas where a direct frontal a
