Handheld Confocal Endomicroscope System with Tremor Compensation for Retinal Imaging

IROS 2025

Advancements in biophotonics have driven the development of miniaturized imaging probes for high-resolution in vivo imaging. Probe-based confocal laser endomicroscopy (pCLE) enables cellular-level visualization of tissues but remains challenging for retinal imaging due to the need for non-contact op

A three-dimensional compliant bowtie-shaped mechanical amplifier to magnify coaxial displacement in a confined space

ICRA 2024poster

This paper proposes a novel form of a three-dimensional coaxial bowtie-shaped mechanical amplifier. The proposed model incorporates a lever mechanism into the Sarrus linkage structure. It allows the target plate to move along one axis with amplified displacement in a parallel manner. The amplifier w…

An Optical Interferometer-based Force Sensor System for Enhancing Precision in Epidural Injection Procedure

IROS 2024poster

In minimally invasive pain management procedures, precise needle positioning is paramount for effective treatment and patient safety. Traditional techniques like the loss-of-resistance (LOR) method may be insufficient, especially in patients with narrowed epidural spaces. The use of imaging tools su…

Exploring Robot-Assisted Optical Coherence Elastography for Surgical Palpation

ICRA 2023poster

Optical Coherence Elastography (OCE) is a method that discerns local tissue stiffness using optical information. This method has recently been explored for laryngeal cancer tumor margin detection but has not been widely deployed clinically. Part of the challenge hindering such clinical deployment is…

A Deep Learning Technique as a Sensor Fusion for Enhancing the Position in a Virtual Reality Micro-Environment

IROS 2022poster

Most virtual reality (VR) applications use a commercial controller for interaction. However, a typical virtual reality controller (VRC) lacks positional precision and accu-racy in millimeter-scale scenarios. This lack of precision and accuracy is caused by built-in sensors drift. Therefore, the trac…
