Course description and aims
[Course description]
Starting with the physical meaning of digital image information, the relation between radiometry and photometry is discussed. Next, the fundamental knowledge required for understanding image acquisition, processing, and display systems is explained, such as geometrical optics and aberration theory, basics of wave optics, Fourier analysis of optical imaging systems. According to this theoretical background, the characteristics of an imaging system are discussed, such as the resolution and the depth of field of an imaging system, along with the examples of a digital camera, video, and microscope. In addition, the basic theory of color science is introduced along with the application to the color imaging and display. Finally, the principle and limitations of 3D image acquisition and display technology are discussed based on the knowledge of geometrical and wave optics.
[Aim]
Based on the concept of optics as information media, students will understand the characteristics of optical imaging systems by learning the fundamentals of geometrical optics, wave optics, radiometry, and photometry. Since the transmission of visual information is mainly mediated by light, gaining the knowledge of optics enables students to deal with the visual information systems, optical measurement devices, and other related systems. Moreover, the students will grasp the technical components required for the development of practical systems.
Student learning outcomes
By the end of this course, students will be able to
1. Explain the fundamentals of geometrical optics, wave optics, radiometry, and photometry,
2. Comprehend the concept of optics as information media, and apply it to understand the characteristics of optical imaging systems,
3. Find the appropriate direction to learn more details for the development of practical imaging systems.
