METHOD AND DEVICE FOR INTEGRATING OPTICAL SIGNALS WITH RESPECT TO TIME Russian patent published in 2002 - IPC

FIELD: computation engineering. SUBSTANCE: method involves using parallel light beam incident onto integrating unit composed of transparent dielectric layers equal in optical thickness and separated with partially reflecting metal layers or having refraction index variable according to given law. Light beams reflected from medium separation boundary are composed of identical optical pulses delayed one relative to another that form a signal when superimposed in space that is in proportional relation with respect to integral of impulse over time. EFFECT: high performance and accuracy of integration. 4 cl, 5 dwg
