unreferenced date January 2012 For the cult film publication see Phantom of the Movies Videoscope A flexible Videoscope or Video Borescope is an advanced type of borescope that houses a very small Charge coupled device CCD chip embedded into the tip of the scope. The video image is relayed from the distal tip and focusable lens assembly back to the display via internal wiring. This is unlike a traditional borescope and fiberscope . Borescopes use hard optical relay components to transfer the image from the tip to an eyepiece and Fiberscopes use coherent image fiberoptics to relay the image to one s eye through an eyepiece. The image quality of a videoscope is superior to a fiberscope and could be compared to that of a high end Video Camcorder. Videoscopes are normally 10 mm or less in diameter and come in lengths up to 50 ft. Several integral features include the insertion probe section, the articulated tip, articulation controls up down left right on the control handle, lighting bundle, high intensity external light source and cable interface with outputs to the display LCD or CRT and external media recording device such as computer hard disk or compact flash card. The system normally will record either live video or still photos. As either an AC or DC portable visual inspection system, the components are designed to be compact and be hand carried without shipping cases on wheels or large boxes.

Orphan date December 2010 unreferenced date December 2009 Remote Visual Inspection , also known as RVI, refers to a specialty branch of nondestructive testing NDT . RVI is commonly used as a predictive maintenance or regularly scheduled maintenance tool to assess the health and operability of fixed and portable assets. The remote portion of RVI refers to the characterization of the operator not entering the inspection area due to physical size constraints or potential safety issues related to the inspection environment. Tools Common tools used for RVI are as follows Video borescope s Rigid borescope s Flexible fiberscope s Pan Tilt Zoom cameras Push cameras Applications Typical applications for RVI include Aircraft engine s turbofan , turbojet , turboshaft Aircraft fuselage Turbines for power generation Steam turbine steam and Gas turbine gas Process piping oil and gas, pharmaceutical, food preparation Category Nondestructive testing Category Maintenance Category Tests ... more details
Image Fiberscope view inside clock .png thumb 240px right A low quality fiberscope observing the inside of an antique clock mechanism. Note how individual fibers are discernable, as each fiber only relays one general color. A fiberscope is a flexible fiber optic bundle with an eyepiece at one end, and a lens at the other. It is used for inspection work, often to examine small components in tightly packed equipment, when the inspector cannot easily access the part requiring inspection. The lens is often a wide angle lens, and the eyepiece is occasionally instead connected to a camera. Some fiberscopes use an additional fiber to carry light from an external source to illuminate the material being inspected, for clearer viewing. All fiberscopes introduce a certain amount of image distortion much of this is similar to the distortion of modern night vision equipment. br Quartz fiberscopes can reach lengths of up to about 90 m 300 ft ref http www.qualitymag digital.com qualitymag ndt supp200706 ?pg 26 quartz fiberscope info from NDT magazine dead link date January 2011 ref Fiberscopes are used in medicine , machining , computer repair, espionage , locksmithing , safecracking , and computer forensics , among many other uses. In popular media Perhaps one of the first exposures the public had to the fiberscope s use in counter terrorism was the 1982 film Who Dares Wins film Who Dares Wins , about the Special Air Service SAS .

Infobox media name Video Floppy logo image Image Video Floppy Disk front gabbe .jpg thumb A Video Floppy disk caption type encoding NTSC , PAL capacity read write standard owner Sony use extended from extended to A Video Floppy is a analog recording storage medium in the form of a 2 magnetic floppy disk used to store still frames of composite video composite analog video . A video floppy, also known as a VF disk , could store up to 25 frames either in the NTSC or PAL video standards, with each frame containing 2 field video field s of interlaced video . The video floppy also could store 50 frames of video, with each frame of video only containg one field of video information, recorded or played back in a skip field fashion. Video floppies were first developed by Sony with name Mavipack in 1981 for their Mavica still video camera not to be confused with their later line of Mavica digital cameras introduced in the mid 1990s, which stored JPEG images to standard 3.5 floppy disks readable by computers instead . The video floppy format was later used by Minolta , Panasonic , and Canon company Canon for their still video cameras introduced in the late 1980s, such as the Canon Xapshot from 1988 also known as the Canon Ion in Europe and the Canon Q PIC in Japan . Besides still video cameras, stand alone recorders & players were also available for the VF format, that could record from or output a composite video signal, to or from an external source such as a video camera , VCR , video capture card , or computer graphics output . Some VF recorders also had the feature of recording a couple of seconds of audio that accompanied each video frame. Uses of the Video Floppy The video floppy saw a lot of uses during its heyday in the 1980s and 1990s, besides being used for still video cameras. Many medical endoscopy and dentistry video systems, as well as industrial video borescope s & fiberscope s, used VF disks for storing video images for later playback and study.

Image NDT test of an V2500 engine blade route.jpg thumb right 400px An example of Ultrasonic Testing UT on blade roots of a V2500 International Aero Engines IAE aircraft Turbofan engine . br Step 1 The UT probe is placed on the root of the blades to be inspected with the help of a special borescope tool video probe . br Step 2 Instrument settings are input. br Step 3 The probe is scanned over the blade root. In this case, an indication peak in the data through the red line or gate indicates a good blade an indication to the left of that range indicates a crack. Unreferenced date December 2009 In ultrasonic testing UT , very short ultrasound ultrasonic pulse waves with center frequencies ranging from 0.1 15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement , which tests the thickness of the test object, for example, to monitor pipework corrosion. Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is a form of non destructive testing used in many industries including aerospace , automotive and other transportation sectors. How it works In ultrasonic testing, an ultrasound Ultrasonic sensors transducer connected to a diagnostic machine is passed over the object being inspected. The transducer is typically separated from the test object by a couplant such as oil or by water, as in immersion testing. There are two methods of receiving the ultrasound waveform, reflection and attenuation. In reflection or pulse echo mode, the transducer performs both the sending and the receiving of the pulsed waves as the sound is reflected back to the device. Reflected ultrasound comes from an interface, such as the back wall of the object or from an imperfection within the object. The diagnostic machine displays these results in the form of a ... more details
