Optical implementation of a time-domain beam former.
We report on an optical implementation of a time-domain beam former that uses a low-cost, low-power, twodimensional spatial light modulator (liquid-crystal television) to generate eight beams from eight sensors. The optical architecture can be classified as a vector-matrix multiplier. The vectors are formed from sampled sensor values by a low-power total-internal-reflection electro-optic device, and the readout is done with a linear photodiode array detector. The experimental response of the broadside beam is given.
