Spatial Resolution, Surface Roughness Improved in Laser Fabrication

Facebook X LinkedIn Email
A research group at Osaka University in Suita, Japan, reports that the spatial resolution of two-photon polymerization laser fabrication and the surface roughness of objects created using the technique may be improved with the addition of radical quenchers and control of scanning pitch, respectively. Presenting their findings in the Feb. 14 issue of Applied Physics Letters, the scientists conclude that the minimum resolution of the technique is limited by the material properties of the polymer rather than the laser setup and that the surface roughness is sufficiently low for use in...Read full article

    spatial resolution
    Spatial resolution refers to the level of detail or granularity in an image or a spatial dataset. It is a measure of the smallest discernible or resolvable features in the spatial domain, typically expressed as the distance between two adjacent pixels or data points. In various contexts, spatial resolution can have slightly different meanings: Imaging and remote sensing: In the context of satellite imagery, aerial photography, or other imaging technologies, spatial resolution refers to the...
