Title: Innovations by Samuel N. Fersht in Micro-Actuation and Optical Systems

Introduction

Samuel N. Fersht, based in Studio City, California, is a prominent inventor with an impressive portfolio of 24 patents. His innovative work primarily spans the fields of micro-actuators and optical systems, contributing significantly to advancements in technology.

Latest Patents

Fersht's latest patents include a bi-stable micro-actuator and an optical switch. The bi-stable micro-actuator is ingeniously designed using two silicon-on-insulator wafers that are fused at an electrical contact layer. It features a cover with a V-groove that defines an optical axis and incorporates a collimated optical signal source to couple an optical signal effectively. The actuator utilizes a transfer member with a mirror surface that can block or reflect the optical signal, depending on the state of the device. Furthermore, an expandable structure applies compressive force to maintain the transfer member in either a bowed first or second state, dictated by a control signal applied to a heating element within the structure.

Additionally, his patent for an unbalanced fiber optic Michelson interferometer presents a system capable of measuring variations in environmental parameters such as velocity or pressure. This innovative setup includes an optical signal source providing coherent light, an interferometer with unequal optical path lengths, and a movable mirror that responds to environmental changes. The interference signal generated from this process is detected and analyzed to reveal valuable information about the parameter being measured.
