Purpose of the Study:
- To develop a novel technique for retrieving the 3D shape of dynamic objects.
- To enable simultaneous projection and processing of distinct optical patterns for enhanced data extraction.
Main Methods:
- Simultaneous projection of a fringe pattern and a homogeneous white light pattern, encoded in an RGB image.
- Iterative least-squares method for phase map retrieval from the fringe pattern.
- Object pixel matching across consecutive images using the white light pattern for dynamic scene analysis.
Main Results:
- Successfully demonstrated the simultaneous projection of two distinct patterns.
- Achieved effective extraction of object information and phase map retrieval concurrently.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
