Shaping field for 3D laser scanning microscopy. [PDF]

open access: yesOpt Lett, 2015
Imaging deep tissue can be extremely inefficient when the region of interest is nonplanar and buried in a thick sample, yielding a severely limited effective field-of-view (FOV). Here we describe a novel technique, namely adaptive field microscopy, which improves the efficiency of 3D imaging by controlling the image plane.

A 3D-printed 3D actuator for miniaturized laser scanning probes

open access: yesSensors and Actuators A: Physical, 2021
Abstract Imaging of tissue sections at multiple depths with a miniaturized optical imaging probe necessitates 3D actuation capability. A number of MEMS studies in literature have addressed 3D actuation either through a single scanning unit with three degrees of freedom, or combination of multiple scanning units each having one or more degrees of ...

A 3D actuator for laser scanning endoscopy

open access: yesMOEMS and Miniaturized Systems XIX, 2020
We present a miniaturized actuator for volumetric tissue imaging. The device consists of a hydraulically actuated accordion-like part for axial scanning (focus adjustment), and an electromagnetically actuated 2D scanner for lateral scanning. The device is manufactured using selective laser sintering, allowing for very low cost and rapid production.
