Design and application of new generation micro-lens arrays (MLA) with free-form surfaces and irregular arrangement of segments
On demand | Presented live 19 June 2024 
Abstract
Novel MLA geometries and design methods are introduced, enabling 'second-generation' and 'third-generation' products. They offer higher flexibility in lens segment design and expand the range of possible applications and associated performance. The second-generation MLA features lens segments with different freeform surface shapes, and irregular arrangement intervals between segments. This product enables simultaneous measurements of multiple depth points while controlling image intensities. The third-generation MLA is created using a topology optimization method based on internal stresses, allowing the unsupervised design of optical segments. The designed freeform segments can be used to convert a Gaussian beam into multiple and flexible distributions of light beams.

Atsushi Sasaki is a software developer in the field of optical design, employed at ANAX Optics Inc. He earned a bachelor's degree in aerodynamics from Tokai University and pursued studies at Lille University. During his formal education, he undertook an internship in aero-thermic design of gas treatment system at Fives Solios Ltd.
After obtaining his master's degree in fluid dynamics in 2018, he initiated his professional career as a ventilation engineer at Edvance. His responsibilities included the design of air conditioning systems and radiation decontamination systems for nuclear power plants.
In 2021, he redirected his career towards optical design. Currently, his primary focus involves developing software that facilitates the design of free-form and multi-focus lens and mirror elements through user-friendly manipulation. He is actively engaged in studying generative AI for a design support system, proposing multiple starting-point designs for lens systems.
