Pierre Jacquinot (18 January 1910 – 22 September 2002) was a French physicist.

Jacquinot was a PhD student of Aimé Cotton.

[2] In the mid-1940s, Jacquinot noticed that a Michelson interferometer could be modified by removing the need of a slit to achieve a higher resolution.

[3] In Laboraotire Aimé–Cotton, he advised the work of Pierre [fr] and Janine Connes who developed the Fourier-transform infrared spectroscopy between 1954 to 1966.
