LIGHT SCANNING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240264550 titled 'LIGHT SCANNING APPARATUS

The patent application describes an apparatus that deflects a light flux from a source to scan a surface while rotating at a constant speed, with an optical system guiding the light onto the surface.

  • The width of the light flux on the deflecting surface is larger than the surface itself.
  • The scanning speed of the light flux is highest at the center of the image and decreases towards the edges.
  • The scanning acceleration of the light flux increases from the center towards the outer edges of the image.

Potential Applications: - This technology could be used in laser scanning systems for high-precision imaging applications. - It may find use in industrial automation for quality control and inspection processes.

Problems Solved: - Provides a method for efficient and accurate scanning of surfaces with a rotating deflecting unit. - Ensures consistent scanning speed and acceleration across the entire scanned surface.

Benefits: - High precision scanning for detailed imaging applications. - Improved efficiency in scanning processes. - Consistent image quality across the entire scanned surface.

Commercial Applications: Title: High-Precision Laser Scanning System for Industrial Automation This technology could be utilized in industries such as manufacturing, automotive, and electronics for quality control and inspection purposes, improving production efficiency and accuracy.

Questions about the technology: 1. How does the scanning speed vary across the scanned surface? - The scanning speed is highest at the center of the image and decreases towards the edges for uniform scanning. 2. What is the advantage of having a larger width of the light flux on the deflecting surface? - A larger width ensures more coverage on the surface, leading to more efficient scanning.


Original Abstract Submitted

provided is an apparatus including: a deflecting unit configured to deflect a light flux from a light source to scan a scanned surface in a main scanning direction while rotating at a constant angular velocity; and an optical system configured to guide the deflected light flux onto the scanned surface, wherein, in a main scanning cross section including an optical axis of the optical system, a width of the light flux on a deflecting surface of the deflecting unit is larger than a width of the deflecting surface, wherein a scanning speed of the light flux on the scanned surface is highest at an on-axis image height, and wherein an absolute value of a scanning acceleration of the light flux on the scanned surface increases monotonically from the on-axis image height toward an outermost off-axis image height.
