5 Parallel information processing and photon echo 5.1 Properties of the photon
echo effect The photon echo effect (or time domain four wave mixing effect) was
predicted in 1962 by Kopvillem and Nagibarov [6], and was experimentally
observed two years later by Kurnit, Abella, and Hartmann in a ruby crystal [7].
This is a nonlinear optical phenomenon, analogous to a spin echo effect, that
consists in the coherent response of optical inhomogeneously broadened
mediums (gases, ...

There will be as many repetitions of the echo as there are reflecting surfaces —
the regularity and distinctness of the answering voiee being dependent upon the
distance, &c. Travelers give accounts of many places in this and other countries
where the echo effect is very interesting — almost unaccountable. We have in our
younger days been highly entertained by the answering voiee from some large
building, — from some streets of particular construction, having high solid walls
on ...

This leaves very little of the "echo effect" mentioned earlier. The considerations
now put forward suggest, rather, that equipment installed during one surge of
investment demand will tend to be replaced whenever the next surge comes
along, rather than after some fixed and predictable time lag. 8. Changes in the
Price Level Decisions about replacement may be complicated by changes in the
general level of prices during the life of the equipment. An increase in the price of
capital ...

This limitation can be disguised to some extent using either echo or reverberation
. Echo can be introduced by using a continuous tape loop. This has a recording
head and three or more pick-up heads located at different positions round the
loop. When a sound is played into the echo unit the output consists of the original
sounds plus a number of repetitions of diminishing amplitudes, similar to the
echo effect produced in a large and very reverberant room. Many modern echo
systems ...

Everyone knows the “HELLO, Hello, hello” echo effect. In the early days ofaudio
recording, this was created using a tape recorder having separate heads for
recording and playback. A tape recorder with separate record and play heads
can play back while recording, and the playback is delayed slightly from the
original sound letting you mix the two together to get a single echo. The delay
time depends on thetape speed, as well as the distancebetween the record

... but on encountering the crack they are diffracted down it and up the other side.
The length of time a particular wave takes to travel between one probe and the
other can be used to calculate the crack's depth. At Harwell, researchers have
used the instrument to measure cracks one centimetre deep, with a normal
operating accuracy of between 025 and 0.5 mm. Most similar gauges use
ultrasound as well but work on the echo effect or the fact that the wave amplitude
is proportional to ...
