Signal Processing Algorithms For Doppler Lidar Sensors, Samantha Grubb
Signal Processing Algorithms For Doppler Lidar Sensors, Samantha Grubb
Physics and Astronomy Honors Papers
Light detection and ranging (LiDAR) is a remote sensing technology that obtains relative distance and velocity measurements between a sensor and a defined target by using light transmitted and received from the target. FMCW Doppler LiDAR, a particular variant of LiDAR, functions by analyzing the frequency shift in the reflected light to determine the target's range and velocity. This technology plays a crucial role across various sectors including defense, aerospace, and automotive. This paper presents signal processing algorithms designed to optimize data obtained from Doppler LiDAR sensors. By applying various window functions to time domain data, the Signal-to-Noise Ratio (SNR) …

There are great opportunities for advancement in the realm of infrared (IR) optics through the use of chalcogenide glasses (ChGs). The development of IR optics using ChGs is important for applications in search and rescue operations, firefighting efforts, medical imaging, and satellites. Instead of creating bulky, expensive, single crystal IR glasses, ChGs can be deposited as thin films by solution derived (SD) spin or dip coating. Our research takes a multidisciplinary approach to investigate ChGs thin films using physics, chemistry, optics, and materials science.
Investigation Of Spin And Dip-Coating Phase Change Chalcogenide Materials As A Novel Technique For Coating And Functionalizing Conformal Optics, Paul Vecchio
Physics and Astronomy Summer Fellows
Chalcogenide glasses (ChGs) have excellent infrared (IR) transparency ranging up to 20 μm, large nonlinear refractive indices, and tailorable thermo-optic coefficients (dn/dT) that have great potential for applications in detectors, sensors, waveguides, imaging devices, photonic waveguides, acousto-optics, and optical devices. Spin and dip coating ChGs from solution is a low-cost, simple, and scalable method for depositing films over a large area. In this study, we utilize the novel approach of spin and dip coating to create thin ChG films of arsenic trisulfide (As2S3) and arsenic selenide (As2Se3). To realize the full potential …
