An endoscope designed for visual inspection of narrow, difficult-to-reach spaces, when coupled with an Android-based smartphone, becomes a portable and versatile diagnostic tool. These devices typically consist of a long, flexible tube with a miniature camera and LED illumination at the distal end, which transmits live video to the phone. A practical application includes examining the internal components of an engine without disassembly.
The ability to visually assess confined areas without invasive procedures provides significant advantages across various fields. This facilitates preventative maintenance, reduces downtime, and minimizes the need for costly repairs. Its usage builds on the historical development of endoscopy, extending its accessibility and convenience through modern smartphone technology.
