Jean-Claude Perrin Consultant - Engineering in Optics and Optronics

About Us

Jean-Claude Perrin is graduated from Ecole Supérieure d'Optique (1970) , with a specialization in coherent optics (DEA 1971) and PhD (1974) .

He then spent five years at the Brown Boveri (ABB) research center in Paris and Zürich.

En 1977, he integrated the French company Télécommunication Radioélectrique et Téléphonique (TRT) business center of the Philips company .

The PhD thesis was conducted at the Institute of Optics (Orsay) with Professor Serge Lowenthal. G.W Goodman and L. Mertz where members of the jury, with A. Marechal and P. Bouchareine.
The subject was coherent image processing applied to the Fourier transform spectrography. It consist in recording an interferogramm on a photographic plate and then to extract the information.
Signal to noïse ratio and dynamic where also compared to what is obtained with the classical slit spectrograph.
A prototype of this instrument has been constructed.

Themas of the team of the research center, which was directed by Professor René Dändliker, where non destructive technics using holography, speckle and Moiré technics applied to deformation and strain measurements and also to dimensionnal metrology of large structures.
Several publications have been made, and especially the booklet: "Perspectives et applications de l'holographie en métrologie", still available at the French Bureau National de Métrologie.

Worse noting is the first introduction in Europe of commercial applications of holographic displays in 1975.
.

In 1991, he moved to the French company Société Anonyme de Télécommunications (SAT), part of the Sagem group.

TRT has developed and produced the first thermal imagers in 8 to12 microns for the needs of the French army. Also a speciality of TRT was night intensification equipments (googles, episcopes), laser guidance and aerial photography.
In 1987, Philips decided to desengage from this field and sold this business group of TRT to the THOMSON company to form a new entity which is now the Optronic part of THALES.
Jean Claude Perrin expertise extended then to laser designating and navigation pod's.

Fields of interest where second generation themal imagers using focal plane arrays, seekers, optronic surveillance and civil applications (Lidar, spectroscopy ATR, CO2 laser ).
SAT has been integrated to SAGEM in 1997 and then to SAFRAN in 2005.

En 1995, he founded JCPC.

Jean Claude Perrin Consultant provides consultancy and optical design services based on it's experience and expertise. The company is using the most efficient softwares which are available today. JCPC experience is now covering a large scope in the spectral range from 157 nm to 1mm, with projects made in the fields of optronics, medical, photolithography, lidar, photography, space...
