Description
This comprehensive course, "Introduction to Optical Eye Modeling with Zemax," is meticulously designed for optical engineers, researchers, and professionals working in areas such as retinal imaging, AR/VR optics, and other vision-related technologies. The course equips learners with a profound understanding of both the theoretical foundations of optical systems and their practical implementation in Zemax OpticStudio.The course begins by covering the essential principles of geometrical optics, including the laws of reflection and refraction, thin lenses, focal length, optical power, and image formation. Learners will also explore critical concepts such as dispersion, the Abbe number, and nasal-temporal distinctions. A thorough treatment of aberration theory follows, with a focus on both monochromatic and chromatic aberrations, including defocus, spherical aberration, coma, and astigmatism.A significant portion of the course is dedicated to modeling the human eye as an optical system. Students will delve into the detailed anatomy and optical properties of the cornea, including its refractive index, power, and asphericity, as well as the crystalline lens, with an emphasis on thickness, curvature, and refractive index distribution. The course also covers accommodation of the eye, including a practical example of calculating the amplitude of accommodation.Utilizing Zemax OpticStudio, students will build a paraxial schematic eye model and the more advanced Liou and Brennan schematic eye model. Participants will gain hands-on experience in simulating and analyzing optical performance, detecting aberrations, and optimizing lens designs for enhanced results. Practical exercises, including the design of a singlet lens and the modeling of the Navarro 1985 accommodated eye, are incorporated to deepen the learners' practical skills.By the end of the course, participants will have a solid foundation in both the theoretical and practical aspects of optical eye modeling and will be fully equipped to apply these skills to complex optical systems. This course is ideal for those seeking to master Zemax OpticStudio in the context of advanced optical modeling and simulation.
