PUPIL-STEERING FOR THREE-DIMENSIONAL (3D) RESOLUTION ENHANCEMENT IN SINGLE PHOTON AVALANCHE DIODE (SPAD) EYE TRACKING (ET) - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240192493 titled 'PUPIL-STEERING FOR THREE-DIMENSIONAL (3D) RESOLUTION ENHANCEMENT IN SINGLE PHOTON AVALANCHE DIODE (SPAD) EYE TRACKING (ET)
The three-dimensional (3D) resolution of a single photon avalanche diode (SPAD) based eye tracking system is improved by utilizing sensor and/or light source steering. The light source can illuminate the entire eye, while the sensor and/or mirrors associated with the sensor can be directed to capture images of different sections of the eye. These images are then stitched together to create a high-resolution, comprehensive view of the eye. Alternatively, the sensor can capture a low-resolution image of the entire eye and be steered to capture multiple low-resolution images, which can be interpolated to generate a high-resolution image of the eye. Both the light source and the sensor (and/or mirrors) can be steered to illuminate and capture images of various parts of the eye, which are then stitched together to produce a detailed, full view of the eye.
- Key Features and Innovation:
- Utilization of sensor and/or light source steering to enhance the 3D resolution of a SPAD based eye tracking system. - Ability to capture images of different portions of the eye and stitch them together for a high-resolution, comprehensive view. - Option to capture multiple low-resolution images and interpolate them to create a high-resolution image of the eye.

Original Abstract Submitted
three-dimensional (3d) resolution of a single photon avalanche diode (spad) based eye tracking system is enhanced through sensor and/or light source steering. the light source may illuminate the whole eye, while the sensor and/or one or more mirrors associated with the sensor may be steered to capture images of different portions of the eye. the images are stitched to achieve a high-resolution, full view of the eye. alternatively, the sensor may capture a low-resolution image of the whole eye and be steered to capture multiple low-resolution images, which may be used for interpolation and creation of a high-resolution image of the eye. both the light source and the sensor (and/or the mirrors) may be steered to illuminate and capture images of different portions of the eye, which may then be stitched to achieve a high-resolution, full view of the eye.
