摘要
实时全息是一种全场、无损、高精度的实时检测方法。介绍了应用这种方法应注意的若干关键技术,包括获得高衬比的干涉条纹、获得高亮度检测光场、获得无畸变的衍射图像等新技术,还介绍了实时全息在科学技术、工业、医学等方面的一些应用近况。
Real-time holographic interferometry is a testing method with high precision, non-destructive and full field. Based on the recent developments in real-time holography, some key points in real-time holography are introduced in this paper, such as how to obtain high contrast of interference fringes, how to obtain high brightness of the testing field, and how to obtain good quality replay image without aberration etc. Some new applications to science and technology are also introduced.
