全像光聚合物光柵–從創新材料及製程開發與動態模型、全像光柵混合光學元件、全像光柵單模雷射掃頻次系統開發到連續波調頻光學雷達系統研究

The project has three major goals which are 1. Material and fabrication process,2. Hybrid optics and frequency tuning single longitudinal mode laser sub-system,and 3. PQ/PMMA VBG FMCW Lidar.1. The material and fabrication part focuses on developing of 3D printedphotopolymer and solvent-casting photopolymer film. In the meantime, improvedrecording and testing method will be established to identify and investigate thecharacteristics of the photopolymers using reaction and diffusion rate equations.2. The second part of this proposal is to combine the holographic recording andgeometrical optics making capabilities of PQ/PMMA for constructing hybridoptics. In the meantime, frequency-tuning-single-longitudinal-mode diode laser isconstructed using the developed PQ/PMMA VBG and will be thoroughlycharacterized.3. The core of the FMCW LiDAR is frequency-tuning-single-longitudinal-laser.With the development of VBG-feedback laser, an FMCW LiDAR system can beestablished along with a fiber-based interferometer and a DAQ sub-system.
