CONTROLLING EXPOSURE APPARATUS USED IN IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111248 titled 'CONTROLLING EXPOSURE APPARATUS USED IN IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes a system for adjusting exposure amounts of light sources on an exposure head based on correction gains stored in a memory and temperature data detected by a sensor.
- Light sources are mounted on a substrate with a condensing optical system.
- Correction gains for exposure amounts are stored in a memory.
- A sensor detects temperature.
- A processor acquires correction gains based on the position of a light source that reached an exposure timing.
- The processor corrects exposure amounts of each light source using the corresponding correction gain.
- The processor adjusts reference positions of correction gains in the profile based on the temperature detected by the sensor.
Potential Applications
This technology can be applied in various industries such as semiconductor manufacturing, lithography, and 3D printing where precise exposure control is crucial.
Problems Solved
This technology solves the problem of inconsistent exposure amounts in light sources due to temperature variations, leading to improved accuracy and quality in the final product.
Benefits
The benefits of this technology include enhanced precision in exposure control, increased efficiency in production processes, and improved overall product quality.
Potential Commercial Applications
Potential commercial applications of this technology include advanced photolithography systems, LED manufacturing equipment, and high-resolution printing devices.
Possible Prior Art
One possible prior art could be systems that adjust exposure amounts based on sensor data, but the specific method of using correction gains stored in a memory based on light source positions and temperature data may be unique to this patent application.
What is the specific method used to acquire correction gains in this system?
The specific method used to acquire correction gains in this system is based on the position of a light source that reached an exposure timing.
How does the system adjust reference positions of correction gains in the profile?
The system adjusts reference positions of correction gains in the profile based on the temperature detected by the sensor.
Original Abstract Submitted
an exposure head includes a substrate on which light sources are mounted, and a condensing optical system. a memory stores a profile indicating correction gains for exposure amounts. a sensor detects a temperature. a processor acquires a correction gain that corresponds to a position of a light source that reached an exposure timing, corrects, for each of the light sources, an exposure amount of the light source with the correction gain corresponding to the position of the light source, and adjusts, for each of the light sources, a reference position of the corresponding correction gain in the profile in accordance with the temperature detected by the sensor.
