Abstract
Focused light field cameras utilize microlens arrays (MLAs) as an imaging system to obtain spatial and angular information. MLAs are efficiently fabricated by thermal reflow whereas MLAs formed by thermal reflow have relatively small f-numbers, resulting in small depth-of-field. Here we report a focused light field camera with large f-number by incorporation solid immersion MLAs. Solid immersion using PDMS spin coating over conventional MLAs facilitates large-area fabrication of large f-number MLAs using refractive index differences. Solid immersion MLAs extend depth-of-field several times. This method can broaden focused light field camera application range.
