Additionally, it comes with 24 months of updates for free, keeping the software completely up to date with all the newest vehicle information year after year. And while the tool will certainly get all the newest information each year if you pay for the subscription, you also don’t need to pay for it to keep using all the existing features. The anterior angle is the drainage channel for fluid inside the eye. If the drainage channel is not working properly, it can lead to an increase in eye pressure, and cause damage to the optic nerve and vision loss. Fig. 1 Full-field OCT optical setup. Components include: super-luminescent diode (SLD), convex lens (L1), 50/50 beamsplitter (BS), camera objective (CO), CMOS-DSP camera (CAM), reference (REF), and sample (SMP). The camera functions as a two-dimensional detector array, and with the OCT technique facilitating scanning in depth, a non-invasive three-dimensional imaging device is achieved.Next time you come in for an eye test, your optometrist can compare new scan results with old ones. This can help with early diagnosis by detecting the smallest changes to the retina. NatWest, Royal Bank of Scotland (RBS) and Ulster Bank, which are all part of the NatWest Group, will now shut at least 172 of their bank branches in 2023 and 2024. Overall it’s extremely compact, but the wired handheld portion is a bit larger than the BlueDriver scan tool. There’s nothing wrong with the handheld device, but it creates a scan tool that’s a bit clunkier and more cumbersome to use compared to the BlueDriver one that lets you do everything on the app. The principle of OCT is white light, or low coherence, interferometry. The optical setup typically consists of an interferometer (Fig. 1, typically Michelson type) with a low coherence, broad bandwidth light source. Light is split into and recombined from reference and sample arms, respectively. These updates put in the information for vehicles from the newest model years and provide more information about specific issues for older vehicles. However, these subscriptions are far from free. They typically cost hundreds of dollars each year, which can significantly add to the overall cost of the scan tool.

The tool reads codes, gives you live data streams, and even works when driving so you get all the information necessary to figure out what’s going on with your vehicle. It’s also easy to use and works with all OBD2 vehicles.

Scanning for OTC Breakouts

But while you’re spending a lot more for the Launch X431 V+ PRO, it also comes with tons of additional features that help justify the higher price tag. First, there are over 35 service functions you can use to complete and speed up repairs. The tool is extremely easy to use, and while it’s expensive, it also comes with a 5-year warranty so you don’t have to worry about anything happening to it any time soon. Moreover, it comes with two years of subscription-free upgrades so it can keep working on all the new vehicles that hit the market each year. The first US patents on OCT by the MIT/Harvard group described both a time-domain OCT (TD-OCT) system [6] [7] and a Fourier-domain OCT (FD-OCT) system of the swept-source variety. [6] These patents were licensed by Zeiss and formed the basis of the first generations of OCT products until 2006. Tanno et al. obtained a patent on optical heterodyne tomography (similar to TD-OCT) in Japan in the same year. [8]

This is the most basic feature, so any automotive scan tool should be able to do this. You don’t need a ton of information on each code though because you can always research further troubleshooting information on your own. Fig. 3 Spectral discrimination by swept-source OCT. Components include: swept source or tunable laser (SS), beamsplitter (BS), reference mirror (REF), sample (SMP), photodetector (PD), and digital signal processing (DSP) Identify most CAN vehicles (year, make, model, engine) in under 5 seconds - less time waiting and more time fixing When you’re shopping for the best automotive scan tool for car diagnostics, there’s no better choice than the BlueDriver Bluetooth Pro. It doesn’t look like much, but that’s part of the appeal. Fig. 4 Spectral discrimination by Fourier-domain OCT. Components include: low coherence source (LCS), beamsplitter (BS), reference mirror (REF), sample (SMP), diffraction grating (DG) and full-field detector (CAM) acting as a spectrometer, and digital signal processing (DSP)NatWest, RBS and Ulster Bank to close at least 172 branches in 2023/24 – here's the full list, plus alternatives The OCT scanner is CE marked and the low powered laser light is safe, and cannot harm your eye. The OCT scan is suitable for use with people fitted with pacemakers or metallic implants and you can wear your hearing aid throughout the procedure. Can I refuse to have an OCT scan? Add in the 10.1″ color touchscreen and it’s never been easier to navigate to the right screen and see all the information at once. It works with over 10,000 vehicle models, and each device comes loaded with 24 different languages so everyone in the shop can use it. Whether it’s abnormal performance specs or a faulty sensor, live data helps you narrow everything down without the need to tear a ton of parts of your vehicle and test a ton of individual components. The Scoop on Service Functions Still, while it’s an outstanding choice for DIY mechanics, it doesn’t have all the advanced features a professional would want, and you need a smart device to use it. Not only that, but because of the smaller size it’s easy to lose the device if you don’t have a secure spot for it.
