In this study, a dual-band hybrid filter that achieves high excitation light rejection performance in a lensless imaging system was fabricated and incorporated into an imaging device. The hybrid filter consisted of interference and absorption filters, and a fiber optic plate (FOP). The interference filters were attached to both sides of the FOP, wh...

We demonstrate a hybrid “package-less” polydimethylsiloxane (PDMS)–complementary metal–oxide–semiconductor (CMOS)-FR4 system for contact imaging. The system embeds the CMOS image sensor directly in a PDMS layer instead of the standard chip package to support microfluidic structures much larger and more complex than those in prior art. The CMOS/PDMS...

Oxygenation is one of the skin tissue physiological properties to follow for patient care management. Furthermore, long-term monitoring of such parameters is needed at the patient bed as well as outside the hospital. Diffuse reflectance spectroscopy has been widely used for this purpose. The aim of the study is to propose a low-cost system for the ...

Spatially resolved diffuse reflectance spectroscopy (srDRS) is a well-established technique for noninvasive, in vivo characterization of tissue optical properties toward diagnostic applications. srDRS has a potential for depth-resolved analysis of tissue, which is desired in various clinical situations. However, current fiber-based and photodiode-b...
Nous utilisons une méthode optique récemment développé pour mesurer l'aire de contact réelle à l'interface entre une surface élastomère et une plaque de verre. Nous montrons d'abord que l'aire de contact réelle diminue significativement sous cisaillement. Ensuite, nous comparons nos mesures avec deux modèles de la littérature. Nous utilisons ces ré...

Chip-scale microscopy imaging platforms are pivotal for improving the efficiency of modern biomedical and bioscience experiments. Their integration with other lab-on-a-chip techniques would allow rapid, reliable and high-throughput sample analysis for applications in diverse disciplines. In typical chip-scale microscopy imaging platforms, the light...
Un vidéomicroscope permettant un suivi en temps réel, crucial en biologie cellulaire, est souvent cher et encombrant. Mon projet de thèse vise à développer un vidéomicroscope miniaturisé. L'objectif est de permettre, à terme, une meilleure parallélisation des expériences, mais également de favoriser une intégration avec d'autres capteurs, en l'envi...
