Abstract
We propose a wide FOV aspherical glass MLA for high power Flash LiDAR applications. The proposed MLA combines high power endurance, transmittance, and reliability, overcoming the drawbacks of polymer on glass MLA. We investigated the maintenance of a flat-top intensity distribution in the output beam, noting that the aspherical MLA's divergence angle must surpass the VCSEL's divergence angle. Additionally, we also developed and verified the wide FWHM of the aspherical glass MLA, which manipulated through microlens aspect ratios and pupil ratio design. This innovative device enhances Flash LiDAR performance for long-range ranging.
