Work Experience
Hanbat National University (2018.09 ~ Present)
Daejeon, Korea
Assistant Professor @ Dept. of Smart Manufacturing Applied Engineering
Honam University (2017.03 ~ 2018.08)
Mainly research opto-mechanical fabrication and measurement instruments for smart factory environments such as automated inspection solutions and high resolution on-demand fabrication solutions. In addition, I’m also working with Prof. No-cheol Park’s Lab in Yonsei Univ. to develop ultra-high-resolution STED nanoscopy.

Assistant Professor @ Dept. of Automotive Engineering
S-Printing Solution (2010.11 ~ 2017.02)
Mainly researched optical sensors (including optical system design and optoelectronic sensor unit integration) for Advanced Driving Assistant System (ADAS) such as solid state LIDAR and stereo cameras.
Suwon, Korea
Principal Engineer (2016~ Present) @ Printing Solution Business
Samsung Electronics (2009 ~ Present)
Mainly researched the yield improvement in the manufacturing process by reconstructing the lightguide optical system in the 10.1 "and 7" IR TSP (touch screen panel) and establishing a complete measurement process for the detailed main optical parameters.
Suwon, Korea
Principal Engineer (2016~ Present) @ Printing Solution Business
Worked to solve opto-mechanical issues related to a laser scanning unit (LSU) in a digital printer, such as reduction of systematic Moire in image and difference in optical density. In addition, researched annular pupil apodization and effect on diffracted field by birefringence distribution in the F-theta lens.
Senior Engineer (2009~ 2015) @ Printing Solution Business
Philips (2006)
Internship Program
During 4.5 years, designed optical systems for a laser scanning unit (LSU) of a color copier by using CODE-V, optics design S/W. Key thing was to design a zoom optics considering a polygon mirror and free-form shaped F-theta lenses. During remained 2.5 years, developed a LED print head. Mainly concerned array structure of LEDs and LED driving method. In addition, researched image correction on vertical noise by optical power fluctuation of each LED.
Einthoven, The Netherlands
Constructed interferometric evaluation setup for the optics with a solid immersion lens and focused EM field analysis in a multi-layered medium.
Samsung Adv. Inst. of Technology (SAIT) (2003)
Kiheung, Korea
Internship Program
Worked on fabrication of diffractive optical element with gray-scale lithography for small form factor optical disk drive information storage device.
