WebOptics has three major branches: Geometrical optics, Physical optics and Quantum optics. Chapter 1 is about the nature of light. Geometrical optics is covered in chapters 2 to 5, Physical optics in chapters 6 to 8, and Quantum optics in chapter 9, and lays a foundation for advanced courses in applied quantum optics. WebThe DOE structure partially resembles that of a grating, which creates multiple peaks in the point spread function (PSF, right). Intuitively, this PSF creates three shifted and scaled copies of the input image. ... Deep Optics for Depth Estimation and Object Detection. ICCV 2024 ; Peng et al. 2024.
