Title: Jean-Michel Sajer and Bolometric Detection Technology.

Introduction

Jean-Michel Sajer is an inventor associated with Audenge, France, and the Commissariat à l’énergie atomique et aux énergies alternatives (CEA). His work includes a patent for detecting millimeter and sub-millimeter waves using a bolometric device. The patent record lists 1 patent for him.

Latest Patents

Sajer’s listed patent, “Bolometric Detection Device for Millimeter and Sub-Millimeter Waves,” describes a device and a method for manufacturing it. The invention forms at least one bolometer on a support that is transparent to the waves being detected. Each bolometer includes a reflecting resonant cavity, a thermally insulated grid positioned above the cavity, regular conductor patterns on the grid, and a thermometer integrated with the grid. The conductor patterns are designed to have an electrical impedance matched to that of the void.

Career Highlights

The patent reflects work on bolometric detection, a technique that measures radiation through the heating effect it produces. The device’s arrangement combines a resonant cavity, patterned conductors, and an integrated thermometer to detect millimeter or sub-millimeter waves.

Collaborations

The patent information identifies Patrick Agnese as Sajer’s coworker. Sajer is also associated with the Commissariat à l’énergie atomique et aux énergies alternatives, a French research organization.

Conclusion

Jean-Michel Sajer’s listed invention presents a structured approach to bolometric detection of millimeter and sub-millimeter waves, combining a resonant cavity and thermally responsive components in a single device.
