COI synopsis: London Line saw a queue outside London’s Royal Academy announcing an exhibition under the title "Light Fantastic". So went in to find out what was going on and discovered an exhibition of...
The principle of holography is studied with the aid of a progression of optical demonstrations and laboratory experiments. Shows types of holograms, explains holographic interferometry, and illustrates the...
Examines the three-dimensional images produced by holograms. The programme is chiefly concerned with the possibilities of holography as a medium for display and illustration. Begins with an experiment which...
Support video for course ST291, comprising four older programmes. [See synopses of individual programmes for details of content.]
Explains what a hologram is and shows the step-by-step construction of a transmission master camera. Explains how we see in three dimensions and how that relates to holography, and how a flat plate gives a...
The difference between the incoherent nature of normal light sources and the coherent light from a laser is explained. Animated diagrams show the essential parts of a laser and how the energy of stimulated...
This video explains what laser light is, how it originates, and how it is used. Shows how lasers are widely used today in industral applications as well as in medical and surgical procedures. The video also...
Shows how the linear diode array camera and fibre optics are used to measure fine holes in combustion chambers and turbine blades of aero-engines. Also shows the use of laser holography to check...
Shows the use of holographic interferometry to record minute surface deformations on objects, particularly to study vibrating objects. Shows interference fringes in real time produced by a hologram....
Shows the basic notions of time coherence and space coherence by means of simple models such as coupled pendulum circuits. Various types of laser and some of their applications, including the hologram...
