Proposal and Implementation of an Integrated Continuous–Discrete Optical Computation Model Using Light Intensity as State

English Description This work proposes a new optical computation model that directly uses light intensity (lux) as the computational state. A continuous‑value light‑intensity cell is constructed using a VEML7700 sensor, enabling smooth state transitions at 5 Hz under low‑cost, room‑temperature conditions. Building on this model, an 8‑state optical CPU is implemented by exploiting the 3‑bit structure of an RGB LED (R=1, G=2, B=4). Through calibration, light intensity is mapped to discrete states, enabling integer operations such as addition, subtraction, comparison, XOR, and carry generation to be performed entirely using light. This study demonstrates a practical and low‑cost optical computing framework based on classical light intensity, distinct from interference‑based and quantum photonic approaches. 日本語 Description 本研究は、光強度(lux)
