研制激光二维或三维显示器的研究者所面临的难题是高昂的成本。目前 ,激光显示器面临着价格便宜得多的传统技术的强劲竞争 ,尽管这些技术可能缺少激光图像的质量。只有降低价格 ,激光显示器才能成为未来大多数人使用的技术。全息视频的发展1 96 5年激光发明后不久 ,全息图像、 The challenge for researchers developing laser 2D or 3D displays is the high cost. Currently, laser displays face stiff competition from much cheaper traditional technologies, though these technologies may lack the quality of laser images. Only by lowering prices can laser displays become the technology most people use in the future. Holographic video development 1 96 5 years after the laser was invented, holographic images,
