Abstract: An object detection device may include: a converter configured to convert a transmission signal radiated towards an object into a digital transmission signal and a received signal reflected from the object into a digital received signal, according to a predetermined sampling period; and at least one processor configured to: interpolate between elements of the digital transmission signal and the digital received signal that have the predetermined sampling period, to obtain an interpolated transmission signal and an interpolated received signal; remove noise from each of the interpolated transmission signal and the interpolated received signal; generate a cross-correlation signal between the interpolated transmission signal from which the noise is removed and the interpolated received signal from which the noise is removed; and acquire a three-dimensional (3D) image of the object based on at least one peak value of the cross-correlation signal.

Abstract: A memory system in accordance with an embodiment of the inventive concept includes a memory controller comprising a controller optical transmission unit photoelectrically-converting a data signal to output a first optical modulation signal and a second optical modulation signal, a first memory device which is optically connected with the memory controller to receive the first optical modulation signal, and a second memory device which is optically connected with the memory controller to receive the second optical modulation signal. The first optical modulation signal and the second optical modulation signal are complementary to each other.
