Holography using lasers
Holography involves two processes: recording and reconstruction. During the recording phase, reference light is superimposed with light reflected from the object onto a holographic plate, creating interference fringes. After the plate is processed in a darkroom, diffraction is used to reconstruct the interference pattern on the photosensitive film, producing an image that perfectly replicates the original object. Unlike conventional photography, which captures only the amplitude of an object’s light field, holography also records the relative phase of the reflected light waves. As a result, holography has found extensive applications in fields such as holographic microscopy, anti-counterfeiting technologies, data storage, deformation measurement, and holographic interferometry.
Changchun New Industries Optoelectronics Technology Co., Ltd. (CNI) was established in 1996 as a high-tech enterprise based on the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences. The company primarily focuses on the research and production of solid-state lasers and semiconductor lasers, offering high-performance, highly reliable products tailored for OEMs, scientific research, industrial applications, and other customers. CNI has successfully obtained several international certifications, including ISO9001, the European CE certification, the EU RoHS environmental protection certification, the U.S. FDA certification, and the Japanese JQA certification. Today, the company can provide single-frequency laser sources, ultra-narrow linewidth lasers, and related accessories designed for imaging, communications, and holography applications.
