Latest Patents

Yilin He's latest inventions include two groundbreaking patents:

1. **Ultrafast Photographing Apparatus Based on Polarization-Time Mapping**

This invention relates to an ultrafast photographing apparatus designed to capture spatiotemporal data (x, y, t) of dynamic scenes with a single exposure. The system comprises an active illumination component, a synchronous control system, a data acquisition mechanism, and a data reconstruction unit. The active illumination system emits light to illuminate the dynamic scene, while the synchronous control system manages the camera's single exposure. The data acquisition system collects a two-dimensional image that incorporates spatiotemporal aliasing facilitated through polarization modulation and filtering. Subsequent reconstruction of this image is performed using an iterative Tikhonov regularization algorithm, allowing for the restoration of sixteen frames of the original dynamic scenes.

2. **Compressed Ultrafast Imaging Velocity Interferometer System for Any Reflector**

This patent introduces a compressed ultrafast imaging velocity interferometer comprised of a light source-target setup, an etalon interference system, a compressed ultrafast imaging system, a timing control unit, and a data processing system. By replacing traditional imaging devices with a compressed ultrafast imaging method, this system enables the reconstruction of multi-frame, three-dimensional images from a single measurement. The technology captures the full dynamic process of two-dimensional interference fringes, thus effectively acquiring spatiotemporal evolution information regarding shock waves, which significantly improves the performance of conventional imaging velocity interferometer systems.
