摘要： An optical coherence tomography image system and an autofocus method thereof are provided. The autofocus method captures a reference chart at a plurality of preset diopter positions, receives an interference signal generated by the reflection of a light beam projected onto an eyeball, and analyzes the reference chart and the interference signal to obtain an analysis value and a corresponding diopter. The method compares the plurality of analysis values to obtain one meeting the standard condition as the target analysis value. According to the target analysis value and the corresponding diopter, the focusing driving device is controlled to move to the position corresponding to the diopter to complete autofocusing. Therefore, the present invention can reduce the time of autofocusing, obtain a higher shooting success rate, provide better user experience, and use a lower-order computing device to reduce costs.

摘要： The invention provides an optical coherence tomography self-testing system, an optical coherence tomography method and an ocular disease monitoring system. The optical coherence tomography self-testing system comprises a camera device, an external display module and a communication module. The camera device includes an image-capturing module and a processing module. The image-capturing module captures a plurality of ocular images. The processing module is connected to the image-capturing module, and the processing module determines whether a position offset value between the pupil center position of a tested eyeball and an optical axis of the image-capturing module is within a preset error range. If the position offset value is within the preset error range, the plurality of ocular images is stored as a plurality of displayed images. The external display module displays one of the plurality of displayed images and a status light after the image-capturing module has completed image capturing.
