METHOD OF SPACE-TIME MODULATION OF OPTICAL RADIATION Russian patent published in 1994 - IPC

FIELD: optoelectronic instrumentation engineering. SUBSTANCE: optical radiation beam is additionally directed n times to reflecting space-time light modulator by means of multipass optical system formed with use of light modulator as one of optical components; spatially coinciding intermediate pictures with single linear magnification are formed on reflecting space-time light modulator. Additional reflecting space-time light modulators are employed which present mirrors of multipass optical system optically coupled with reflecting space-time light modulator. EFFECT: enlarged functional capabilities. 2 cl, 1 dwg
