Title:
OPTICAL COMPUTATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024414
Kind Code:
A1
Abstract:
An optical computation device (1) is provided with an optical computation unit (11) that includes an optical modulation element (11ai), and an image sensor (12) that generates an electric signal representing an intensity distribution of signal light output from the optical computation unit (11). A phase modulation amount of each of cells constituting the optical modulation element (11ai) is set such that a direction in which the signal light (SLi) is emitted is different from a direction in which noise light (NSi) is emitted. In this way, an optical computation device is achieved in which the influence of noise light on an electric signal generated by an image sensor is reduced.
