Integrated Optical Probes For Confocal Scanning Imaging And Adjustable Coherent-Gated Dynamic Sensing
Abstract
Optics and photonics have been one of the most important sciences and technologies that impact modern human life in a big way. For example, fiber-optics for communications and artificial intelligence. Optical probes are critical components for optical imaging and optical sensing technologies that have been actively researched and developed in the past decades. Advanced fiber-optic sensor probes with smaller size, better performance, lower noise, higher photon efficiency, rapid sensing time, and lower cost are needed in many applications, such as nanoscale material science, chemistry, and biomedical fields, etc. In this project, new fiber-optic sensor probe technologies and integrated micro-optic devices have been studied, fabricated, and characterized. It shows the potential to improve optical confocal scanning imaging and LC-DLS sensing capabilities and performance. First, an optical relay uses a single-piece multiple-pitch long Gradient Index (GRIN) lens that is studied for deep optical imaging and optical sensing. A single-piece multi-pitch GRIN lens relay is selected, designed, fabricated, and tested in photoacoustic imaging (PAI) and multi-photon imaging (MPI) systems. A new coaxial aberration correction unit (ACU) is studied to improve imaging quality of the single-piece long multi-pitch GRIN lens imaging probe by reducing its aberrations; Second, new integrated fiber-optic probe configurations are studied, fabricated, and characterized for LC-DLS measurements. These…
