![]() Consequently, there have been many studies of fast CGH calculation methods, such as look-up table (LUT)-based 1, 2, 3, 4, 5, sparsity-based 6, 7, 8, polygon-based 9, 10, 11, 12, and hardware-based 13, 14, 15 approaches. However, the enormous calculation requirements for producing computer-generated holograms (CGHs), which are displayed on an SLM to modulate the incident light, are a significant problem for practical applications (e.g., for an interactive 3D display for a car navigation system). Numerical and optical experiments using a dataset of handwritten inputs show that the proposed system is capable of reproducing handwritten 3D images in real time with sufficient interactivity and image quality.Įlectro-holography is a very promising technology for three-dimensional (3D) display systems, because it is possible to reproduce fully the light reflected from an object using a spatial light modulator (SLM). ![]() In this system, we used an SLM with 1,920 \(\times \) 1,080 pixels and a pixel pitch of 8 μm × 8 μm, a drawing tablet as an interface, and an Intel Core i9–9900K 3.60 GHz CPU. The proposed system integrates an efficient and fast CGH computation algorithm for line-drawn 3D objects with inter-frame differencing, so that the trajectory of a line-drawn object that is handwritten on a drawing tablet can be played back interactively using only the CPU. Here, we demonstrate an interactive 3D display system using electro-holography that can operate with a consumer’s CPU. However, the enormous computational requirements for calculating computer-generated holograms (CGHs)-which are displayed on an SLM as a diffraction pattern-are a significant problem for practical uses (e.g., for interactive 3D displays for remote navigation systems). Barefoot, President,Īt (860) 663-3030.Holography is a promising technology for photo-realistic three-dimensional (3D) displays because of its ability to replay the light reflected from an object using a spatial light modulator (SLM).
