Fig. 5: High-speed imaging through the microlens array camera (MAC).
From: Multi-functional imaging inspired by insect stereopsis
a Schematic illustrations of capturing a fast-moving object through the MAC. b The original photograph of a fan with two wings. The scale bar is 2 cm. c The imaging of “a rotating fan” captured by the conventional single-lens camera (CSLC). The image captured through the CSLC shows motion artifacts due to the rolling shutter effect. Scale bar, 3 cm. d The array images of “a rotating fan” captured by the MAC. The camera captures different moments in each row of channels without motion artifacts. The scale bar is 8 cm. e Reconstructed images of array images in the horizontal direction by using the high dynamic range (HDR) merge. Scale bar, 8 cm. f Schematics for image distortion due to the rolling shutter effect. g The captured images of a rotating 6-color disc through the CSLC and the MAC. The image distortion is reduced as the lens diameter (L.D.) decreases. Note that colors appear slightly different due to chief ray angle (CRA) mismatching according to lens diameters. h The measured arc distortion of each color in the rotating 6-color disc. The error bars represent standard deviations (n = 5).
