Logic array devices having complex macro-cell architecture and methods facilitating use of same. A quarter-wavelength plate is disposed in the transparent substrate, and a polarization plate is disposed on the surface at the forward side thereof in the light-incident direction. A third doped region is disposed between the second doped region and the undoped region. First and second reception units calculate arrival angles and reception levels of reflected waves calculated from respective reception signals which are obtained by receiving the reflected waves by the first and second beam patterns.
