EVENT PREVIEW PHOTONEX & VISION UK MULTIPIX STAND D11
In 2015, the University of Bath completed a refurbishment of the 50m swimming pool used to train top athletes. Part of the re-fit included an imaging system commissioned by British Swimming and UK Sport for the purpose of advanced training, which is used to improve swimming techniques, including those competing at the Rio 2016 Olympics. The vision hardware was supplied by Multipix Imaging whilst the bespoke software was written by Dr Simon Goodwill, a research engineer in Sports Engineering at Sheffield Hallam University. He has developed a range of customised software applications which link data acquisition hardware with camera systems which are being used to help improve an athlete’s performance. The vision hardware is mainly based on Basler acA2000-50gc, running
2,048 x 1,000pixels @ 50fps. There are 12 cameras along the length of the lane and one camera each end of the lane where the swimmer enters the water. In addition, there are three cameras placed high above the pool for an overhead view of the lane. Each camera is using Kowa LM5JCM, 5mm megapixel lens, as it was important to achieve the widest field-of-view possible due to the change in refraction index from air to water. To ensure camera protection, each is housed in a AutoVimation ORCA IP67 enclosure. All cameras must be synchronised which, until very recently, would have
required additional trigger cabling to run to each camera and a common trigger source. For installation, where space is constrained, the thought of running multiple cables over 50m+ distances is not ideal. However, this was simplified greatly with the use of Basler GigeVision cameras supporting PTP
and PoE. The extremely neat solution means only the CAT6e cable is required to run from each camera back to a NETGEAR switch which is connected to the 19in rack PC for image capture, analysis and replay. PTP (Precision Timing Protocol) was introduced to GigeVision 2.0 and is a way to synchronise cameras using the GigE cable interface and eliminates the needs for traditional triggering via a dedicated hardware port on the camera. This is a great example of where industrial vision components are being
used in sport analysis and the growing trend of non-industrial imaging solutions. Find out more on the Multipix Imaging stand at Photonex 2016.

Three leading scientists in the field of hyperspectral imaging will be speaking at HSI 2016, which takes place alongside Photonex and Vision UK on 12th and 13th October at the Ricoh Arena in Coventry. The conference is opened by Martin Whitworth
from Campden BRI (UK), an organisation deeply involved in research and support to the food industry. His talk is entitled “Mapping composition in food samples by NIR hyperspectral imaging” and follows, amongst others, more papers on food applications including; early detection of fungal infection in strawberry fruits, rapid detection and visualisation of organic spelt flour adulteration and the differentiation of pathogenic bacteria. In the second session attendees can hear how
neurosurgeons are now using hyperspectral imaging in the fight against cancer, it assists in the identification of healthy brain tissue to avoid
STEMMER IMAGING
STEMMER IMAGING will be showing its new hyperspectral imaging capabilities at Photonex. This technique utilises the near infrared absorption behaviour of organic objects to reveal chemical composition information. Also on show will be a multi-camera packaging inspection system. Hyperspectral imaging opens up innovative new inspection possibilities for
machine vision users. Based on an intuitive, configurable data processing software platform from Perception Park that makes the scientific methods of hyperspectral analysis readily accessible to everyone, STEMMER IMAGING’s hyperspectral systems allow the identification and separation of substances based on chemical information. This is not possible using conventional colour or monochrome imaging. Hyperspectral imaging has applications in industries as diverse as pharmaceutical, medical, food processing, recycling, mining and wood processing and for document inspection. A multi-camera packaging inspection system will also be shown to determine print quality, read
alphanumeric and barcode data and check fill-level as boxes pass underneath. This demonstration will show how cameras with different interfaces (USB3 Vision and GigE Vision) and varying resolutions can be combined to meet different inspection needs.

unnecessary injury during operations to remove tumours. Keynote speaker Dr Himar Fabelo from the Universidad de Las Palmas de Gran Canaria will be talking about the “The HELICoiD project: A comprehensive framework for real-time detection of human brain tumours using hyperspectral images”. Visiting from the Center for Imaging Science,
Rochester Institute of Technology in the USA, is Professor Vodacek a specialist in remote sensing. He will be speaking on the HSI activities at their centre and giving insight into phenomenology, algorithms, modeling and simulation and applications for hyperspectral imaging. The conference comprises 24 speakers over the
two days and includes a ‘Poster Session’ which will be a chance to meet early career scientists who are researching novel and exciting new techniques and unique applications. Go to:

STAND C20
Alrad Imaging and Alrad Photonics will again be exhibiting at Photonex a wide range of industrial vision cameras and photonic components. Alrad Photonics will display laser
diode modules (including high performance structured light models) laser protection products, photodetectors and laser optics - with a particular emphasis on diffraction gratings and Circular Variable Neutral Density (CVND) filters. Alrad Imaging will display the latest
analogue and digital cameras for machine vision as well as frame grabbers, image sensors, lenses and industrial lighting systems. Of special note are the New Sentech fast USB3Vision camera with Pregius sensor and the short wavelength infrared camera (WiDy) from NIT which also has a fast USB3.0 interface. A high dynamic range InGaAs SWIR
camera will be featured. Megapixel lenses and high Intensity LED lighting will complete the Imaging products offer.
