- Instrument Introduction
The color-coded photography experiment based on white light optical/digital image information processing was developed in accordance with the θ-modulation theory of optical information processing, the Fourier transform theory, and computer digital image processing technology. It utilizes the white light information processing technology—“color photography using black-and-white photographic film”—and the “digital decoding of color-coded images” technology, both of which were researched and invented by Academician Mu Guoguang of Nankai University and his colleagues. The experiment consists of a color-coded photography system, an optical decoding system, and a digital decoding system. The experimental content covers the transmission, transformation, encoding, decoding, filtering, reproduction, storage, recording, extraction, recognition, restoration, and processing of optical information, as well as knowledge in photometry, colorimetry, and computer image processing.
This experimental system is characterized by its comprehensive and flexible nature, supporting purely optical, optical/digital hybrid, and real-time digital image processing. Through experiments with this system, students studying physics and advanced physics can integrate theory with practice to gain a deep understanding of geometric optical imaging, the physical mechanisms of imaging, the Fourier transform properties of optical systems, the spectral concepts of optical information processing and the physical effects of spectral filtering, the principles of color imaging, and the implementation of optical image color decoding via digital computation. It is an experimental system highly favored by both teachers and students.
