Detection and Correction Method for Interferogram Spikes
In this study, a detection and correction method for interferogram spikes is proposed based on filtering and predefined threshold detection to satisfy the requirement of real-time spike detection and correction. We present the algorithm hardware implementation based on a field-programmable gate array. In case of less hardware resources, the detection and correction algorithm achieves high detection accuracy, especially for the spikes of the central fringe of interferogram. The algorithm proposed in this study can be used for real-time on-board interferometric data processing.
