Remote Visual Inspection (RVI) is a term that characterizes inspection in areas that would otherwise be visually inaccessible. RVI enables an inspector to visually inspect these inaccessible areas with a tool that allows this to be done remotely and view otherwise invisible parts of a pipe, engine, gear box, or similar part or assembly. Without RVI, the inspector would have to completely disassemble the entire unit to see to the area of interest.
RVI has a very wide array of applications. They range from the simple, such as pipe blockage inspection, to the advanced, such as jet turbine engine inspection, which can include measurement. RVI plays a crucial role in these fields by improving the safety of equipment used by millions of consumers. In addition, RVI can save an enormous amount of resources by not requiring disassembly or modification of the equipment in order to adequately inspect by eye.
