The Full Field and Multi-Wavelength Wavefront Testing of Head Mount Display and Intraocular Lens(1/2)

The head mount display (HMD) technology (Virtual Reality, Augmented Reality, and Mixed Reality) have been developed for years. The display inside the HMD device have been improved significantly while the optics starts to face different kind of challenges. The optical testing of the HMD is not matured. A subjective method is desired for evaluating the optical system performance of the HMD device other than the MTF testing method. In view of this, we proposed a three-year research project to overcome this issue. In the first two years, we proposed to improve the measurement dynamic range of the wavefront sensor and the mathematical modeling of the optical field of the freeform optics. By calibrating the aberration function of the lens array, adding the multiple wavelength light source, and the optical flat calibration technique, we can improve the optical system of the wavefront to be capable of measuring the HMD. We expect the wavefront sensor could be able to measure the optical field depth, the location of the image, and the wavefront quality of the image simultaneously. In the third year of research proposal, we will use the full field multiple wavelength wavefront testing technology on the intraocular lens testing. With the progression of recent intraocular lens techonolgy, the testing of intraocular lens with multifocal subaperture become nearly impossible. We will then focus the research on wavefront testing such difficult testing intraocular lens application that could include subaperture or multiple wavefront.
