Spectrometry
Context:
La spectrométrie synchrone permet de détecter uniquement la composante alternative du spectre d’un rayonnement optique émis par une source modulée. Cette technique a notamment pour avantage de permettre de s’affranchir d’un rayonnement optique ambiant parasite ou de la lumière du jour, lors des mesures.
Editing task and this has been translated as:
Lock-in spectrometry makes it possible to detect only the alternating component of the spectrum of optical radiation emitted by a modulated source. One of the advantages of this technique is that it allows measurements to be made without the need for ambient optical radiation or daylight.
I read it as a means to overcome the ambient light pollution.
Am I correct?
TIA Chris.

I see it more like this with the precise choice perhaps depending on the mechanism behind this effect.

Johannes Gleim
: The proposal should have been supported with appropriate references. As it is, the translation appears vague and unsure.

eliminates (the need for)
One of the advantages of this technique is that it eliminates the need for ambient optical radiation or daylight during measurements.
Note from asker:

Synchronous fluorescence spectrometry (SFS) has been extensively used in multicomponent analysis. The spectra are obtained through the simultaneous scanning of the excitation and the emission monochromators of a spectrofluorimeter, with a fixed wavelength difference (Δλ) between them. In the synchronous spectra, the sensitivity associated with fluorescence is maintained while offering several advantages: narrowing of spectral bands, an enhancement in selectivity by spectral simplification and a decrease of measurement time in multicomponent analysis

Detection of BaP using conventional fluorescence spectrometry suffers from interference from the homologues of BaP. Synchronous fluorescence spectrometry can simplify spectra, promote selectivity and reduce light scattering interference, making it particularly suitable for analysis of trace PAHs in the environment.

It is up to the questioner to choose the most appropriate translation for the context; incidentally, I had only given one translation variant and implied others.

Annette Fehr
: I think the key idea here is that this microsopy technique eliminates or lessens the risk of ambient light causing interference with the measurements.

Discussion
Apart from the obvious "to free yourself from/to escape", how about "to ignore", as in "not to pay attention to/to take notice of" ? Isn't ignoring something like not letting yourself be bothered by/freeing yourself from its consequences?
