We propose a comparative analysis of DOEs fabricated by multi-level photolithography and grayscale lithography.
We employ B-spline parameterization for the DOE surface geometry representation for RGBD imaging.
The CAL2 project is being built for the GPI calibration system.
We propose a reconfigurable rainbow PIV system that extends the volume size to a considerable range.
We demonstrate a 3D Particle Imaging Velocimetry method by employing a rainbow encoding and 3D optical flow decoding algorithm.
We propose an improved particle swarm optimization method of ultra-thin diffractive optical elements design for multicolour beam shaping.
We introduce numerically optimized encoded phase masks for focus and zoom through changes in the mechanical alignment.
We introduce a diffractive achromat based on computational optimization and a corresponding algorithm for correction of residual aberrations.
We jointly design lightweight diffractive-refractive optics and post-processing algorithms to enable imaging under white light illumination.
