Freeform Optics in Illumination Design
John Koshel
University of Arizona, USA
Invited Speaker
Abstract
Freeform optics have been used in illumination systems for decades. Methods of freeform design will be discussed. A freeform design method for extended sources with the goal of including tolerances in the design process will be explained. Examples, such as a wall-wash illuminator, will be provided.

Abstract
We will discuss why we use Zernike polynomials in wavefront analysis, and what polynomials we should use when the pupil is not circular.
Recent trends in optical aberrations
Jose Sasian
University of Arizona, USA
Invited Speaker
Abstract
This paper provides a review of some recent trends in optical aberrations. There has been progress in understanding and applying a variety of concepts such as the sine condition, aberration fields, pupil aberrations, and polarization aberrations. The talk will present a historical review about the discovery of aberrations, and will proceed to discuss recent advances. The correction of aberrations in a number of noteworthy optical systems will be discussed. Overall the talk will provide a useful review of the topic of optical aberrations.

Hybrid sunlight and LED illumination in indoor lighting
Wen-Shing Sun
National Central University, Taiwan
Invited Speaker
Abstract
Hybrid sunlight and LED illumination with renewable solar energy saving concept in indoor lighting is simulated. We can illuminate the indoor space and collect the solar energy by an optical switching system. When the system is turn off, the full spectrum of the sunlight is concentrated by a concentrator, and absorbed by solar photovoltaic devices that provide the electricity power for LEDs; when the system is turn on, the sunlight is collected by a concentrator and split into visible and non-visible rays by a beam splitter. The visible rays pass through the light guide into a light box and mixed with LED light uniformly in it, and finally provide more uniform illumination by a diffuser. The non-visible rays are supposed to be absorbed by solar photovoltaic devices and also provide the electricity power for LEDs.
Freeform optics and its application in head-mounted displays
Yongtian Wang
Beijing Institute of Technology, China
Invited Speaker
Abstract
Freeform optics can improve the performance of an optical system, and at the same time reduce its size and weight. Special methods for designing freeform optical systems are described. They are applied in the design of freeform head-mounted displays (HMDs), for which the size and weight of the optical system are crucial. The freeform surface optical elements are successfully fabricated and the system performance is carefully examined. It is also shown that freeform optics can be used to realize light-weight and high-performance HMDs, including HMDs with both wide field of view and high resolution, and stereoscopic HMDs with dual focal planes to relieve the discomfort of the user’s eyes caused by the discrepancy of accommodation and convergence.
