“…a high-speed projector (LightCrafter 4500, TI DLP). The dynamic projection range varied from 0.5 m to 2.0 m. The optics system can control the adaptive liquid lens to modify the projection focal length to project a well-focused projection image [147][148][149].…”

An optical zoom imaging system that can vary the magnification factor without displacing the object and the image plane has been widely used. Nonetheless, conventional optical zoom imaging systems suffer from slow response, complicated configuration, vulnerability to misalignment during zoom operation, and are incompatible with miniaturized applications. This review article focuses on state-of-the-art research on novel optical zoom imaging systems that use adaptive liquid lenses. From the aspect of the configuration, according to the number of adaptive liquid lenses, we broadly divide the current optical zoom imaging systems using adaptive liquid lenses into two configurations: multiple adaptive liquid lenses, and a single adaptive liquid lens. The principles and configurations of these optical zoom imaging systems are introduced and represented. Three different working principles of the adaptive liquid lens (liquid crystal, polymer elastic membrane, and electrowetting effect) adopted in the optical zoom imaging systems are reviewed. Some representative applications of optical zoom imaging systems using adaptive liquid lenses are introduced. The opportunities and challenges of the optical zoom imaging systems using adaptive liquid lenses are also discussed. This review aims to provide a snapshot of the current state of this research field with the aim to attract more attention to put forward the development of the next-generation optical zoom imaging systems.

“…A large body of literature exists on projection mapping on static objects [22,[27][28][29][30][31][32][33][35][36][37]. When considering dynamic objects, [2,3,5,7,[10][11][12][13][14][15][16][17][18] handle rigid objects with known geometry in an accurately calibrated non-real-time system. [10,13,14] use specialized high-speed coaxial projector and camera to map specialized planar objects (e.g.…”

“…Projecting onto deformable, non-rigid surfaces can have many applications like visualization, surgical guidance, fashion, retail, design and entertainment. Most prior works avoid accurate reconstruction of deformable surface [2,10,14] or use expensive optimizations [21] to model per-frame deformation explicitly. Therefore, they are not real-time and cannot address stretchable or elastic materials.…”

In addition, to address the problem of the limited depth of field range of projectors, Wang et al utilized the high-speed focus capability of variable focus lens [9][10][11][12][13][14] . It was able to capture changes in the object's distance and attitude through high-speed visual feedback technology, dynamically alter the liquid lens's focal length, and update the projected image in high-speed to correspond with the object's motion in longitudinal space.…”
