In charge of the development and sale of polarization and conventional imaging systems for the cosmetic industry (mainly hair care) for the measurement of gloss, volume, alignment, abrasion/cracking, color, etc.My main activity revolves around :- mechanical / optical development of the product with the rest of the team- testing of camera, motor and sensor controls via Labview / Arduino- complete development of the acquisition, processing and analysis software including user interface via LabViewMy secondary activities include :- sales manager in the US and internationally (Japan, Europe, Brazil, China, Korea, etc.)- technical support for all our systems (including installation, remote support, training, etc.)- website development and maintenance (https://www.bossanovavision.com/)

As a product manager in a small company, I was in charge of all the systems related to cosmetic testing, most of all the development of new systems, including the development (hardware + software) of the SAMBA Hair 3.X version and TANGO in Labview + Labview Vision. On the side, I also had to work on drafting specifications, client relation, technical support, product marketing, scientific communication and created from scratch a brand new website for the company.BOSSA NOVA Technologies became BOSSA NOVA Vision in 2018

Subject : Development of new strategies for laser ignition : application to aero-space propulsionLaser ignition is one of the most promising ignition technology for the next generation of combustion chambers. The concept is to focalise a short duration (~ns) laser pulse to induce a plasma (optical breakdown) at the focal point. It will act as a spark and can lead, in favorable conditions, to a stable flame kernel [1,2].The main objective of my thesis was to caracterize the spatial expansion of the plasma, the shockwave it induced, and measure the temporal evolution of the temperature and electronic density of the plasma using the LIBS technic [3], to have a better understanding of the phyisical processes leading to the optical breakdown and the ignition. A single-pulse configuration was compared to a dual-pulse configuration which showed encouraging resultats for the ignition in harsh conditions [4]. I also undertook optical breakdown tests in non-reactive monophasic and diphasic conditions.References :[1] Ronney, P.

Simulation of the excitation and fluorescence spectrum of the NO molecule using Matlab. The program included a graphic interface.Those calculation were to be used for the detection and NO concentration measurements for LIF (Laser-induced fluorescence) diagnostic in combustion.

Development of a CO2 detector. The device used the infrared absorption of the CO2 molecule to detect its presence. I had to caracterize the performance of existing detectors, and optimize the optical path for a better detection in Mitsubishi detector using ZEMAX.
