Title:
OPTICAL COMPUTATION DEVICE AND OPTICAL COMPUTATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/139922
Kind Code:
A1
Abstract:
The present invention achieves an optical computation device that makes it possible to perform high-speed optical computation while suppressing information loss from binarization. An optical computation device (1) comprises: a spatial light modulator (11) that generates signal light (L1) that represents a wavenumber space image (I1) by binary modulation of carrier light (L0) cell by cell; and a light modulation element group (13) that comprises one or more light modulation elements (13a1–13an) that act in sequence on the signal light (L1).
