We’ve all used thermometers to measure temperature but
sometimes we need to measure temperature in places you can’t put 【S1】______
a thermometer — for example, inside a rocket engine. One of the
best methods for those really hard-to-get-to place is based on laser 【S2】______
spectroscopy. Light from a laser pointing at the region of interest 【S3】______
is absorbed by molecules and some of it are re-emitted back 【S4】______
towards the source where it can be measured. The re-emitted light
is shifted in frequency (changed in wavelength) by amounts that
depend on the molecule and also the temperature and pressure of 【S5】______
the surrounding gas because of collisions among the molecules.
The single, sharp frequency from the laser is thus smeared out in
to a whole spectrum of frequency whose shape can be used to 【S6】______
determine the temperature provided so that the molecular
transitions and line shapes are known. Because it ’is the main 【S7】______
component of the air, it is convenient to use nitrogen since its
molecular properties are known from room temperature to 【S8】______
temperature of about 1,200 degree Celsius from experimental
measurements. Although this is a large range, it is far short of 【S9】______
what it is needed for some applications. 【S10】______
【S7】
