DOI: 10.1002/jbio.202200234
Abstract: Optical‐resolution photoacoustic microscopy suffers from limited depth of field due to the strongly focused laser beam. Here, a novel volumetric information fusion is proposed to achieve large volumetric and high‐resolution imaging. First, three‐dimensional stationary wavelet… read more here.

DOI: 10.1002/jemt.23108
Abstract: Monocular rotational microscopes suffer from shallow depth of field and reduced field of view. Consequently, we propose monocular wide‐field optical microscopy with extended depth of field to enable accurate 3D measurements of micro‐objects. We use… read more here.

DOI: 10.1063/1.5093789
Abstract: Defocus scanning, which causes a serious deterioration of the transverse resolution out of the focal zone, is a big obstacle to the application of optical-resolution photoacoustic (PA) endoscopy (OR-PAE) in imaging internal hollow organs. However,… read more here.

DOI: 10.1063/5.0101426
Abstract: Light-sheet microscopes must compromise among field of view, optical sectioning, resolution, and detection efficiency. High-numerical-aperture (NA) detection objective lenses provide higher resolution, but their narrow depth of field inefficiently captures the fluorescence signal generated throughout… read more here.

Abstract: SIGNIFICANCE Our results demonstrate that blur detection thresholds are elevated in young children compared with adults, and poorer blur detection thresholds are significantly correlated with the magnitude of accommodative microfluctuations. Given that accommodative microfluctuations are… read more here.
