Ophthalmoscopes, which act as an illuminated microscope for the eye, have changed little in design in the last century. As a result the effective operation of the device is constrained by the skill, expertise and eyesight of the eye specialist.
The new digital ophthalmoscope (developed from a three-year research partnership bringing together the University of Warwick, ophthalmoscope manufacturer Keeler Optics, City University, & UCL) uses a combination of specialist lens digital imaging and lighting technology which for the first time allows a high quality digital image to be captured and recorded by an ophthalmoscope.
University of Warwick research Professor Peter Bryanston-Cross has also been able to apply software used to stitch together detailed map images to assemble the captured images from the digital ophthalmoscope. This produces a highly detailed single picture of medical significance and usefulness. It provides a map of the eye equal to the field of view and resolution of the large “Fundus” cameras typically used in hospital settings to examine eyes. The new digital ophthalmoscope would also be around 10 times cheaper than a Fundus camera.
This technology will be a powerful tool in the hands of specialist eye doctors, but it will also revolutionize eye care on the high street. Previously high street opticians have had to rely on notes and hand drawn sketches when referring customers to eye clinics. This new technology will allow them to create and email detailed eye images to hospital specialists cutting patient referral and diagnosis times and massively easing the burden on expensive and overstretched hospital eye equipment.
Warwick Hospital consultant eye surgeon Gary Misson has been working with Professor Peter Bryanston-Cross’s digital ophthalmoscope research digital programme for several years. He says:
“This is an exciting development as it makes an instrument that is traditionally difficult to use much easier to handle and therefore available for use to a wider range of health care workers. It will allow digital images of disease such as the potentially blinding complications of diabetes and glaucoma to be accurately and quickly sent to specialists who will then be able to arrange appropriate treatment. I foresee a relatively inexpensive instrument that is about the size of a mobile phone in common use in the near future”

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
