Description

technical field [0001] The invention relates to the field of image acquisition, in particular to realize a linear array CCD acquisition device under a ZYNQ processor to acquire OCT images. Background technique [0002] Optical coherence tomography (OCT) is a non-invasive, non-contact and non-destructive optical imaging technology, which combines low-coherence interferometer with confocal scanning A differential detection technique that enables high-resolution cross-sectional tomography of microstructures inside biological tissue or other scattering media. OCT technology is based on optical low-coherence reflectometer. This optical testing technology was originally used to detect light and integrated waveguide devices. Later, it was found that it can also be used to detect biological tissues, such as measuring corneal thickness and Axial length. [0003] After optical coherence tomography, a CCD image sensor is required to collect image information. The current embedded de...
