MAE Students Won in the 2017 SPIE Student Poster Session Competition

Two Ph.D. students, Mr. WEN Chenyang and Miss CHANG Yina, from the Department of Mechanical and Automation Engineering under the supervision of Pro. CHEN Shih-Chi, won the student poster session competition in the SPIE International Symposium on SPIE BiOS, part of the SPIE Photonics West 2017 event. The competition was held on 28 January – 2 February 2017 in San Francisco, California, USA.

In the symposium, the MAE participants presented a sync-free light sheet microscope (LSM) based on a static phase mask that eliminates the need of coupling the detection plane, thus enabling high-speed volumetric imaging that is only limited by the speed of cameras e.g. ~1 kHz. In the sync-free design, the emission signals are first guided to the back of a galvanometric mirror, which laterally scans the emissions across a 2-D phase mask, converting it to axial scanning that automatically compensates for the focal shifts in the detection optics. The new method realizes a compact LSM for high-speed 3-D imaging that may find important applications in in vivo biological imaging
