Come join us – we will all learn something new!

October 7th & 8th 2010, The Royal Astronomical Society, Burlington House, Piccadilly, London W1J 0BQ

In October 1910 Professor Robert Wood presented his paper to the Royal Photographic Society in London  “Photography by Invisible Rays”, describing the use of an infrared plate to make a permanent image in the near infrared. Since that time significant advances have been made in infrared thermal imaging, with applications across a broad spectrum from medicine, industry and astronomy.

Two day seminars, the first on the development and general applications of infrared imaging, and the second on infrared imaging in astronomy will be held in London. The first will be organised under the auspices of The Royal Photographic Society, Imaging Science Group, and the second by the Royal Astronomical Society.

The identification of infrared rays is attributed to Sir William Herschel who presented his findings to the Royal Society in 1800. Sir William became the first president of the Royal Astronomical Society that was founded in 1820. In 2009, the Herschel Space telescope was launched carrying a multi-spectral infrared camera system. Some of the first observational images from this current mission will form part of the second day seminar.

As promised, the report and presentations are now on line – see http://www.rps-isg.org/DF2009_presentations.php .

The Low Frequency Radio Array (LOFAR – see http://www.lofar.org/ ) is a radio telescope utilising some fascinating imaging science. Unlike “traditional” radio telescopes such as Jodrell Bank it does not use large expensive dish aerials. Instead it uses large numbers of cheap dipole antennae spread over a wide area. Because this is low frequency imaging science (<100MHz) large diameters are needed to gain resolution.
The really clever bit is combining all these signals with the correct phase relationships to produce an image from a set direction in the sky. The imaging science here is not trivial but the LOFAR scientists believe that they can use their computing power to simultaneously image 8 different areas of the sky.
If you want a glimpse of the mathematics involved in this process it looks like this was covered in a recent paper in the Imaging Science Journal – check out pages 274 to 279 in Volume 57(5).
Think I will stick with optics – the maths looks easier!

To the British Library for their Points of View Photographic Exhibition – see http://www.bl.uk/pointsofview/. Eadweard Muybridge’s study of motion, Edward Sherrif Curtis on Native America and Roger Fenton all feature here. The section on The Search for Permanence is particularly poignant given the work still ongoing for ISO standards in this area!
There a lot of photographic processes featured here. I only had 1 hour – leave yourself longer!

Attended this meeting yesterday – see http://www.rps-isg.org/DF2009_registration.php for the agenda. A joint meeting between the RPS Imaging Science Group and the Institute of  Physics Printing and Graphics Science Groups it was once again a great event. It covered lots of ground around Image Physics and I am part way through writing a visit report so more to follow.

Hope you can join us again next year!

In London for the RPS Revealing The Invisible lecture given by Francis Ring, a contributor to this blog. The occasion was to celebrate Francis receiving the RPS Medical Group Medal, awarded jointly with the Royal College of Surgeons, Royal College of Physicians and Royal College of Obstetrics and Gynaecology. Lots more presented on IR imaging for fever screening and we hope to have more on this posted on http://www.rps-isg.org in the near future.

The event was held at the Royal College of Physicians in London, a wonderful venue – see http://www.rcplondon.ac.uk.
