a Alpha-blending process in two different positions of the sample. After the alpha-blending process, the overlapped edge boundary is much smoother. b Image quality comparison utilizing different imaging methods with alpha-blending in an 800 nm grating line’s structure sample. (i) Optical image without microspheres with a 10× objective lens could not resolve the sample. (ii) Microsphere imaging with a single-camera acoustofluidic nanoscope without alpha blending. (iii) Microsphere imaging with a single-camera acoustofluidic nanoscope with alpha blending. (iv) Microsphere imaging with a dual-camera acoustofluidic nanoscope with alpha blending showed a clear scanned image of the sample.
