This study introduces a novel device to enhance polygon scanners for faster raster scanning imaging. The innovation increases resolvable points per line without sacrificing imaging speed or spatial resolution.
Area of Science:
- Optical engineering
- Microscopy instrumentation
Background:
- Polygon scanners offer high line rates for raster scanning imaging.
- An optical invariant limits the number of resolvable points per line without sacrificing speed.
Purpose of the Study:
- To present a device that enhances the number of resolvable points per line in polygon scanners.
- To overcome the speed-resolvable points trade-off in mirror-based scanners.
Main Methods:
- Theoretical modeling of the device's effect on polygon scanner performance.
- Experimental validation using a simplified facet system and a transmission microscope.
Main Results:
- Demonstrated a 1.7-fold improvement in the field of view.
- Achieved enhanced resolvable points per line without compromising spatial resolution or speed.
Conclusions:
- The developed device effectively increases the field of view in polygon scanner systems.
- This technology offers a solution for faster, higher-resolution raster scanning imaging.
