Welcome to the RTI Group 

The group consists of a range of personnel from various disciplines including computer science, archaeology, natural science, physics and chemistry who combined are attempting to:

  • increase the ability of reflectance transformation imaging (RTI) in terms of clarity and speed of acquisition, for example.
  • push the utility of RTI through production of more mobile and cheaper systems and education of the technique, to ultimately:
  • discover more through RTI!
This website went live as of January 2017 so please come back for regular updates.

  • Summer on campus with The RTI Group Talia Sullens is one of four Exeter Undergraduates choosing to spend their Summer with the RTI Group on an EPSRC Summer Vacation Bursary. Over the next ten weeks, each will write about their experiences, discoveries and challenges faced. Personally, I was initially attracted to the project by the remarkable variety of topographic results that have already been achieved. RTI can do some amazing things and this is only scratching the surface (if you’ll pardon the pun) of the technique. We were first shown the process with the most expensive piece of equipment the group owns and it’s an understatement to say we were nervous about being let loose on it! We carefully watched as the 80 LEDs flashed ...

  • Making a movie... Over the last 7 weeks, myself and two other undergraduate students, Talia Sullens and Thomas Archer, have been working with the RTI group. Alongside developing our own understanding of RTI, we were tasked with producing educational videos that will help us teach others what RTI is, and how we use it: Above is a video of the 'Large dome' set up in Hope Hall, this set up lets us look at archeological samples, ranging in sizes, at very high quality with a Cannon Camera. Below is the 'Small dome' set up, created by Robyn Doherty, to look into the use of RTI on a microscopic level.Making these videos was great fun, and will hopefully help us teach others about ...

  • NatSci Student Conference Last week The University of Exeter hosted the annual NatSci Student Conference. Kony, Alizee and Robyn were there with a poster in practice for their assessment next month.   Comments very much welcome!  A copy of the poster is included below.

  • A matter of scale Imaging a biological specimen in high detail at the cellular level can be a daunting task as undergraduate project student Casey Russell has discovered.  Typically, most imaging techniques are very intrusive to the sample, often providing external influence or even killing the sample. There is also the element of expense, computational as well as cost. An example of this is the use of an electron microscope which uses high energy electrons to create a mapping of the specimen structure depending on its energy absorbency, this process can rip apart the structures within the sample creating implications in repeating the imaging process of the same sample after an arbitrary amount of time. Being able to achieve this cheaply and effectively would ...
