As a PhD student under the Marie Curie Action “Advanced Optical System Design ” project, Yunfeng Nie developed a novel multi-fields direct design method that enables the calculation of 2 freeform optical surfaces that partially couple more than 2 fields.
The methods have been successfully demonstrated on a wide-field line imaging objective, achieving a comparable performance than its spherical counterpart, however with fewer optical elements.
She has applied the developed algorithm for practical applications, such as an ultra-short throw distance projector when taking a short internship at the LPI Company in Madrid. She is currently working towards the prototyping of ultra-short throw distance accessory mirrors for conventional projectors.
The optical imaging system she is working on is based on freeform optical surfaces that are particularly difficult to fabricate. Those optical components are applied in the field of automotive and interior lighting, in advanced manufacturing with lasers, in head-mounted displays used in virtual reality devices and in solar energy/photovoltaic systems. B-PHOT is recognized as one of the global leaders in research concerning the design and fabrication of freeform lenses and mirrors.
Yunfeng is a PhD student in optics and photonics under the guidance of Prof. Fabian Duerr (2012 Kidger Scholar Awardee) and Prof. Hugo Thienpont at the Vrije Universiteit Brussel. Her research is funded by the Marie Curie Initial Training Network "ADvanced OPtical SYStem design" (ADOPSYS) of the European Union's Seventh Framework Programme (FP7). Yunfeng hopes to complete her PhD in early 2018.
First awarded in 1998, the Kidger Memorial Scholarship Awards are given each year to a student of optical design, where the term 'optical design' is meant to include both lens design and illumination design.
The 2016 Kidger Scholarship Award will be presented to Yunfeng at the 2016 UK Optical Design Meeting (UKODM), Rutherford Appleton Laboratory, Oxfordshire, UK, 15 September 2016. For more information, please visit: http://www.kidger.com/mkms_winner_2016.html
