A typical parameter which governs the signal in this case is the " thermal diffusion length ", which depends on the material and the modulation frequency and ordinarily is in the order of several micrometers.
32.
By varying the modulation frequency and wavelength of the probing radiation one essentially varies the probed depth, which results in the possibility of depth profiling and photoacoustic imaging, which discloses inhomogeneities within the sample.
33.
These FM systems are unusual, in that they have a ratio of carrier to maximum modulation frequency of less than two; contrast this with FM audio broadcasting, where the ratio is around 10, 000.
34.
With the introduction of light-emitting diodes ( LEDs ) in 1968 1970, the manufacturers replaced incandescent and neon lamps with LEDs and achieved response times of 5 milliseconds and modulation frequencies up to 250 Hz.
35.
The upper sideband will experience a positive phase-shift, whilst the lower sideband sees a negative phase shift . When these two signals are beat together, the beat frequency will be lower than the modulation frequency.
36.
Generally photodiode detectors are preferred, and are essential for the higher modulation frequencies, whereas slower calibration table, applicable for a particular gas, type of gas, or gas mixture, and sometimes configurable by the user.
37.
Consequently, the spatial resolution achieved by the early AFM-IR approaches was around one micron or more, due to the low modulation frequencies of the incident radiation created by the movement of the mirror in the interferometer.
38.
The turn-on and turn-off lag of an incandescent bulb lies in hundreds of milliseconds range, which makes the bulb an effective low-pass filter and rectifier but limits the practical modulation frequency range to a few Hertz.
39.
In the case of minimal Purcell effect in a classical cavity with small F = Q / V mode, only the first term of equation 1 is considered, and the only way to increase modulation frequency is to increase photon density P 0 by increasing the pumping power.
40.
Polarization modulated ENDOR ( PM-ENDOR ) uses two perpendicular rf fields with similar phase control units to CP-ENDOR . However, a linearly polarized rf field which rotates in the xy-plane at a frequency less than the modulation frequency of the rf carrier is used.
