Fig. 4: Prototype system of Monet for real-world experiment.
From: A multichannel optical computing architecture for advanced machine vision

a Monet network architecture used in the prototype system implementation. b Prototype system built with off-the-shelf optical modulation devices. The red-light path denotes the IU and the blue-light path denotes the DU. c Top, a customized scene with three character-shaped objects ‘T, H, U’. Bottom, the hybrid camera system for dataset capturing. d Optical and simulated interference patterns with 4 different shifts. The number below each column denotes the shift distance of the interference pattern. e Depth maps of numerical simulation, optical result (raw output of the prototype system), filtered optical result and the ground-truth. f Left, depth values along three lines L1, L2 and L3 on the filtered optical result and the ground-truth. Right, the depth-value error distribution of the whole image. g Point clouds generated from the filtered optical results and the ground-truth. SLM spatial light modulator, CAM camera, IU interference unit, DU diffractive unit, Simul. simulation, Px pixel, GT ground-truth
