How does a message travel through a fibre?
The majority of the data transmitted across the Internet is carried using light. Come and find out how light pulses are carried using glass fibres that are the thickness of your hair.
Laser engraver and cutter
One of the most common uses of lasers is in manufacturing. Come and see a high powered laser engraver and cutter in action!
Demonstrating signal interruption
Everything from radio waves to light waves can be used to carry information. The air around us is filled with words. In this demo we will look at how to transmit our very own words through the air. By getting our hands into this experiment we can look at what affects optical communication systems that rely on this basic technology and discover what happens when you try and touch your own words!
Do you know why you were told not to drink dirty water? Grab a laser pointer and discover what lurks in Birmingham canal!
M-squared multicolour panel
A demonstration of high quality white light & multi colour panel operating with strips of light emitting diodes. Emitted light in the panel is controlled by the special electronic module, which is controlled through browser-based user interface from a computer.
Introduction to light: Learn how to bend, bounce and blend light with three high-tech light sources, lenses, mirrors and an activity guide full of fun and learning.
Fibre fuse effect or “Tiny Comet”
The fibre fuse effect is a problem in modern fibre optics telecommunication systems, however, it can make for a stunningly beautiful show!
If a fibre is locally heated to a temperature of 1000C, the laser radiation propagating through the fibre is strongly absorbed by the heated part, increasing its temperature to 104 K. This high-temperature region, seen as a bright white spot, which looks like a comet moving with a velocity of 1 m/s along the fibre.
Create your own laser show using laser diodes, diffractive elements and step motors.on!
This display shows the work of first year electronic engineering students at Aston University. It includes among other things an LED harp, a LED light cube, a mood lamp that demonstrates how different colours can be mixed together to give all colour shades, and a light display that monitors your email inbox.
Interactive LED wall
Did you know most motion sensing technologies use infrared lighting? This demonstration uses infrared sensors to track motion to allow you create beautiful patterns on a LED wall with your hands and body.
Virtual pottery wheel
This virtual pottery wheel allows users to create and adjust a spinning virtual cylinder by passing his or her hand through a laser. When satisfied with the final form, the user can save the customised model.
Diffraction on CD/DVD and smartphone
Ever wonder what the surface of a CD and your smartphone screen looks like? Come and see the wonderful patterns that are generated when a laser strikes these two surfaces.
Why are optical fibres so useful?
Part 1 – Light Refraction, Optics, TIR
Do you know what glass and the Internet have in common? Find out how fibres that are the width of a single strand of hair make the internet work.
Part 2 – Refractive Index; disappearing objects Behaviour of light travelling through an object is very much dependent on its refractive index. Sounds mysterious? Come and see what this really means and how a clever choice of refractive index can make objects disappear!
Part 3 – TIR, lightguiding Optical fibres have enabled high speed Internet communication. Are you aware how they work? Come and see the science behind modern telecommunication!
Fun with optics
Take some time out and enjoy a game with a friend. We have a wide selection of fun games to play and to challenge you!
Multicolor LED in integration sphere
Red, green and blue LEDs will be disposed inside a integration sphere. Each LED will be supplied with its own tuneable current source. The integration sphere will mix lots of colours of light to show the full visible spectrum.
Biophotonics for wellbeing and healthy life
Come and see a laser used for non-invasive monitoring of the human physiological parameters at the fingertip. Anyone can try her/himself for blood microcirculation, tissue oxygen saturation, and metabolism efficiency valuation spending just 3-5 min her/his time. In parallel we will demonstrate main principles of optical non-invasive diagnostic devices and their application for human wellbeing and health life support.
Phosphor light converters
Discover wonderful patterns that can be produced with phosphor light converters.
Light and textiles
Collection of art dresses with embedded light elements (luminescent materials, optical fibres, lasers, LEDS etc.) which are inspired by glowing deep sea inhabitants (jellyfish, deep sea fish, sea anemones, squids etc.) will be demonstrated.
Virtual reality with Google cardboard
See how a regular smartphone display can be used to trick your brain into seeing 3D images. We have a range of video demos that are quite simply amazing! (not recommended for people who suffer from epilepsy or prone to motion sickness).
Show us your musical skills on a laser harp. This exciting laser harp is played by blocking individual laser beams which triggers notes on a synthesizer. This project was sponsored by Hobgoblin Music in Birmingham.
Sound modulated onto a laser beam
How is data transmitted over laser beams? Come and see how you can play music from a phone over a laser beam and play this back using a solar panel and speaker.
