COMPACT IMAGING APPARATUS COMPRISING A FOLDED WIDE ANGLE IMAGING LENS SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18163942 titled 'COMPACT IMAGING APPARATUS COMPRISING A FOLDED WIDE ANGLE IMAGING LENS SYSTEM
Simplified Explanation
The abstract describes an ultra-wide angle imaging apparatus that includes two optics and a prism. The first optics has a negative optical power, the second optics has a positive optical power, and the prism is placed at the intersection of their optical axes. The prism reflects light from the first optics to the second optics, which then transmits the light to an image surface. The entrance surface of the prism has a concave paraxial region.
- The ultra-wide angle imaging apparatus includes two optics and a prism.
- The first optics has a negative optical power, while the second optics has a positive optical power.
- The prism is positioned at the intersection of the optical axes of the two optics.
- The prism reflects light from the first optics to the second optics.
- The second optics then transmits the light to an image surface.
- The entrance surface of the prism has a concave paraxial region.
Potential Applications
- Photography and videography: The ultra-wide angle imaging apparatus can be used in cameras and camcorders to capture wide-angle shots with enhanced image quality.
- Surveillance systems: The apparatus can be employed in security cameras to provide a wider field of view and improved image clarity.
- Virtual reality: The technology can be utilized in VR cameras to capture immersive 360-degree videos and images.
Problems Solved
- Limited field of view: The ultra-wide angle imaging apparatus solves the problem of limited field of view by capturing a wider angle of the scene.
- Image distortion: The combination of optics and prism helps reduce image distortion, resulting in more accurate and realistic images.
- Optical aberrations: The negative and positive optical powers of the first and second optics, respectively, help correct optical aberrations, leading to improved image quality.
Benefits
- Enhanced image quality: The apparatus improves image quality by reducing distortion and correcting optical aberrations.
- Wide-angle coverage: It allows for capturing a wider angle of the scene, providing a broader perspective.
- Compact design: The use of a prism and optimized optics allows for a compact and lightweight design, making it suitable for various applications.
Original Abstract Submitted
An ultra-wide angle imaging apparatus is provided, comprising a first optics having a first optical axis, a second optics having a second optical axis, and a prism placed at an intersection of the first and second optical axis. The prism is configured to reflect light from the first optics to the second optics and the second optics is configured to transmit light from the prism to an image surface. The first optics has a negative optical power, the second optics has a positive optical power, and the prism has an entrance surface for receiving light from the first optics and a reflective inner surface for reflecting light to the second optics. The entrance surface of the prism comprises a paraxial region that is concave.
