数字全息术在未来的三维成像和显示技术中具有很大的潜力。提出了一种在单个数字微镜器件(DMD)上实现全彩色、高速、高保真的动态全息3D显示的方法。我们将相邻微镜的正方形区域组合成可以独立调制幅度和相位的超像素。灰度图像通过幅度调制实现,每种颜色的精确定位通过相位调制实现。该方法实现了基于三基色的全彩色成像,在保持9 kHz的高速开关速度的同时,测量到的结构相似度大于88%,颜色相似度大于98%,从而实现了电荷耦合器件(CCD)的动态全彩3D显示。
Digital holography has high potentials for future 3D imaging and display technology. We present a method for a dynamic full-color digital holographic 3D display on single digital micro-mirror device (DMD) with full-color, high-speed and high-fi-delity characteristics. We combine the square regions of adjacent micro-mirrors into super-pixels that can modulate amplitude and phase independently. Gray images are achieved by amplitude modulation and precise positioning of each color is achieved by phase modulation. The proposed method realizes a full-color imaging based on the three primary colors and achieves measured structural similarity of more than 88% and color similarity of more than 98%, while retaining the high switch speed of 9 kHz, thus achieving dynamic full-color 3D display on charge-coupled device (CCD).
