Abstract
An optical computing device includes: an optical modulation element including cells with independently configurable amounts of modulation; and a reflector. The optical modulation element is configured with N (N is a natural number not less than 2)-computing regions A1, A2, . . . , AN. The computing region A1 performs optical computing by modulating and reflecting incident light. Each computing region Ai (i is a corresponding natural number not less than 2 and not more than N) other than the computing region A1 performs the optical computing by modulating and reflecting signal light that has been modulated and reflected by a computing region Ai−1 and then reflected by the reflector.

An optical computing device comprising:
- an optical modulation element including cells with independently configurable amounts of modulation;
- and
- a reflector, wherein
- the optical modulation element is configured with N-computing regions A1, A2, . . . , AN, where N is a natural number not less than 2,
- the computing region A1 modulates and reflects incident light to generate signal light L1 indicative of a result of optical computing, and
- each computing region Ai, where i is a corresponding natural number not less than 2 and not more than N, other than the computing region A1 modulates and reflects signal light Li−1 that has been modulated and reflected by a computing region Ai−1 and then reflected by the reflector to generate signal light Li indicative of a result of optical computing.
An optical computing method carried out by using an optical modulation element that includes with independently configurable amounts of modulation and for which N computing regions A1, A2, . . . , AN are configured, where N is a natural number not less than 2,
- the optical computing method comprising:
- using the computing region A1 to modulate and reflect incident light to generate signal light L1 indicative of a result of optical computing;
- and
- using each computing region Ai, where i is a corresponding natural number not less than 2 and not more than N, other than the computing region A1 to modulate and reflect signal light Li−1 that has been modulated and reflected by a computing region Ai−1 and then reflected by a reflector to generate signal light Li indicative of a result of optical computing.
