"紧凑型巩膜血管成像装置设计与眼动跟踪应用"

The compact scleral vascular imaging device designed for eye tracking is a revolutionary invention aimed at addressing the limitations of existing portable eye trackers. These limitations include susceptibility to external environmental factors and the variability of user physiological and psychological states. The new imaging device comprises a main lens, a micro-lens array, and an imaging detector. The main lens has a focal length equal to the distance from the eye surface to the main lens, while the imaging detector is positioned at one focal length from the micro-lens array. Additionally, a right-angle prism is used to fold the optical path twice to further reduce the device's size. The optical path includes the imaging object, main lens, right-angle prism, reflection surface 1, reflection surface 2, micro-lens array, and imaging detector. The results show that the device, based on the micro-lens array, achieves clear imaging of the scleral vasculature at close range. It is capable of capturing a multi-aperture image array of the scleral vasculature, exhibiting small volume, large depth of field, and high resolution. In conclusion, the compact scleral vascular imaging device demonstrates promising potential in improving the accuracy and reliability of eye tracking technology. Its innovative design overcomes the limitations of existing portable eye trackers, making it a breakthrough in the field of ophthalmic imaging and eye tracking technology. With further development and optimization, this device has the potential to revolutionize the way eye tracking is conducted, benefiting various fields such as clinical research, human-computer interaction, and behavioral studies.
