In one lecture, Tyndall demonstrated the propagation of light down through a stream of falling water via total internal reflection of the light.
32.
Such fiber uses diffraction effects instead of or in addition to total internal reflection, to confine light to the fiber's core.
33.
Slight differences in the index of refraction between the two layers causes total internal reflection, trapping a light beam inside the inner core.
34.
The core of the waveguide has a higher index of refraction than its surrounding and the light is guided due to total internal reflection.
35.
In optical tweezers, a continuous evanescent field can be created when light is propagating through an optical waveguide ( multiple total internal reflection ).
36.
The Philips type prism includes an air gap with total internal reflection in one light path, while the other prism shown above does not.
37.
:: : : At extremely high frequencies, such as fiber optics, total internal reflection can be described as a form of insulation.
38.
These new assemblies used the property of total internal reflection, within the prisms, to direct the light to the pick-up tubes.
39.
Other optical biosensors are mainly based on changes in absorbance or fluorescence of an appropriate indicator compound and do not need a total internal reflection geometry.
40.
As light travels down an optical fibre, it undergoes total internal reflection allowing for essentially no light to be lost over the length of the cable.
