Abstract

The invention relates to real-time data acquisition system and method of a high-resolution imaging instrument, used in a data acquisition card capable of acquiring data at a high speed and a computer capable of storing data at a high speed. The data acquisition card comprises an interface unit, a buffer unit, a data sending unit and a control unit, and the interface unit is connected with an imaging instrument and can convert an LVDS (Low Voltage Differential Signaling) signal into a TTL (Transistor-Transistor Logic) level signal. The invention solves the technical problems that a traditional image acquisition and storage system can not satisfy the real-time acquisition and storage requirements of high-resolution imaging data. The invention has the advantages of small use size, portability, simplicity, convenience, stable working performance, reliability, and the like.

Description

technical field [0001] The invention relates to an image data acquisition system and method of a high-resolution interference imaging spectrometer. Background technique [0002] The development of high-resolution imaging technology requires efficient image acquisition and storage systems. With the development of high-resolution imaging technology, the need for efficient and reliable image acquisition and storage systems is more urgent. At present, the spatial resolution and temporal resolution of high-resolution imagers have been greatly improved. The throughput of ordinary image acquisition and storage systems is seriously insufficient, which cannot meet the real-time acquisition and storage requirements of high-resolution image data. If the problem of data transmission and storage cannot be solved well, the development of high-resolution imaging technology will be seriously hindered. Therefore, designing an efficient real-time image data acquisition and storage system t...
