Title: A High-Speed Digital Multi-Focal Optical System
Invention: University of Arizona researchers have designed a high-speed digital multi-focal lens system that can selectively focus at one or more multiple focal powers simultaneously. It is a readily scalable design for a wide range of applications, providing high-speed lightfield display systems, without sacrificing field of view, depth of field, or range of focus.
Background: Multi-focal and tunable optics technologies, in which the optical power or a system is tuned without mechanically moving any parts, are key for building high-performance lightfield display systems. Micro-Integrated Imaging (micro-InI) displays that reconstruct the full-parallax 3D lightfield of a scene, have poor performance when used with conventional simple lenslet array structures. To improve the performance, there is a need for a lenslet array structure that yields adequate spatial resolution, depth of field, longitudinal resolution and viewing angle resolution, while operating at a relatively high speed.
- Projection lenses
- Cell phone cameras
- Display monitors
- Microscope/in-vivo imaging equipment
- Head Mounted Displays
- Higher speed focus-selection over a greater range of focus
- Not as dependent on software to auto-focus and correct the image
- Assembly less expensive than aspheric systems
- Improved image quality
