Imaging and Displays Group

  1. 1. The Imaging & Displays Research Group Dr Ian Sexton, Group Leader [email_address]
  2. 2. About the I.D.R.G. <ul><li>Our work involves a wide variety of application domains including: </li></ul><ul><li>computer graphics, </li></ul><ul><li>virtual reality, </li></ul><ul><li>telepresence, </li></ul><ul><li>as well as 3-Dimensional display systems. </li></ul>
  3. 3. About the I.D.R.G. <ul><li>The IDRG has been active at DMU for over 10 years, with many successful PhD students working with us, and we are happy to enjoy an excellent research reputation. </li></ul><ul><li>The research group is led by myself and currently has a staff of three Research Fellows. Historically we have always enjoyed wide and diverse support both at home and abroad. </li></ul>
  4. 4. Funding the I.D.R.G. <ul><li>Recent major projects: </li></ul><ul><li>European: </li></ul><ul><ul><li>‘ ATTEST’ (€6.0 million) </li></ul></ul><ul><ul><li>‘ 3D-TV’ (€6.2 million) </li></ul></ul><ul><ul><li>‘ COGAIN’ (€2.9 million) </li></ul></ul><ul><ul><li>‘ MUTED’ (€4.5 million) </li></ul></ul><ul><li>UK: </li></ul><ul><ul><li>‘ SRIF3’ (£500K) </li></ul></ul><ul><ul><li>‘ KTP’ (£120K) </li></ul></ul>
  5. 5. Our current work… <ul><li>Our current work primarily involves 3-D displays: </li></ul><ul><li>These are ‘autostereoscopic’ displays that show the viewers one image for their left eye, and another image for their right eye - without the use of specialised eye wear. </li></ul><ul><li>By showing a different image to each eye the image on the display looks 3-dimensional, more ‘real’ and more ‘involving’, and more like the real world. </li></ul>
  6. 6. Our current work… <ul><li>Our research aim is to produce a 3-D display that is: </li></ul><ul><li>Autostereoscopic (no glasses). </li></ul><ul><li>Multiple viewer (more than one viewer can see 3-D). </li></ul><ul><li>Mobile viewer (no fixed viewing position). </li></ul><ul><li>This makes our display well suited for television. </li></ul>
  7. 7. Our current work… <ul><li>The next few pages very briefly describe our prototypes of these displays... </li></ul>
  8. 8. Multi-viewer 3D display… <ul><li>Our display is based on projecting left and right eye images into space at the left and right eye positions of viewers. </li></ul><ul><li>Multiple projections can be made to cater for many viewers, and the projections can be steered to follow the eyes of viewers as they move. </li></ul>3D display Steerable projections Multiple viewers Right eye image projection Left eye image projection
  9. 9. MUTED project display… <ul><li>Our MUTED project display employs an RGB laser light source. </li></ul><ul><li>The optics of the display are coupled to a head tracker and direct the RGB illumination through a front LCD to the eyes of the viewers. </li></ul><ul><li>Mobile viewers are accommodated by steering the direction of the illumination. </li></ul>RGB LASER LCOS LCD OPTICAL ARRAY MOBILE VIEWERS HEAD TRACKER
  10. 10. Front panel… <ul><li>The video shows a camera moving between the left and right eye positions on our prototype. </li></ul><ul><li>You can see the transition between green (right eye) and red (left eye) illumination – showing that two images are being generated, one for each eye, from the same screen. </li></ul>
  11. 11. Smart optics… <ul><li>Viewer movement is facilitated by a novel array of lenses and light sources that produce steerable beams of light. </li></ul><ul><li>Each lens is illuminated by the RGB laser (shown here with LEDs for clarity). As a viewer moves, so does the position of the light source. </li></ul><ul><li>The light beam follows the viewer’s eyes. </li></ul>
  12. 12. Miniature light array… <ul><li>We have also developed novel miniature high-brightness light arrays for evaluation before we move to RGB laser illumination. </li></ul>
  13. 13. Miniature lens array… <ul><li>We have also developed novel miniature lens arrays. </li></ul>
  14. 14. Miniature lens array with laser light source… <ul><li>We are now evaluating using the light array with a laser light source. </li></ul><ul><li>The picture shows illumination for a left and right eye being generated from one light array element and a single laser. </li></ul><ul><li>The two separate beams of illumination are clearly defined. </li></ul>
  15. 15. Miniaturised light steering… <ul><li>Many miniature lenses are combined to form an array to illuminate the full width of the screen. </li></ul><ul><li>Here the video shows the illumination being steered. </li></ul><ul><li>Viable commercial solution? </li></ul>
  16. 16. Next steps… <ul><li>The next step in our work is to combine our front screen with our novel light steering array… </li></ul><ul><li>This will form the World’s first 3-Dimensional, autostereoscopic television display, that allows freedom of movement to multiple viewers. </li></ul><ul><li>You are welcome to see our prototype screen and light steering array, as well as a range of other 3-dimensional displays in the I.D.R.G. laboratory this afternoon. </li></ul>
  17. 17. The Imaging & Displays Research Group <ul><li>Thank you for your time. </li></ul><ul><li>Please come and visit us in Gateway House Room 5.81 </li></ul><ul><li>Or contact me, Dr Ian Sexton: </li></ul><ul><li>[email_address] </li></ul>
