PROBLEM TO BE SOLVED: To select a light-receiving signal from each light-receiving element in a discretionary combination, and accelerate a process for measuring the light-receiving value of the selected light-receiving signal.SOLUTION: A multi-input/multi-output MUX 251 sets the connection destinations of input terminals IN1 to IN12 from among output terminals OUT1 to OUT4 by a first control signal from a control unit 21. The multi-input/multi-output MUX 251 controls the connection state of a switch SW between the input terminals IN1-IN12 and the output terminal OUT that is set as a connection destination by a second control signal from the control unit 21. The input destination of a light-receiving signal from each light-receiving element 202 is thereby set from among TIA 261-1 to 261-4. The present invention can be applied to a laser radar device for vehicles.SELECTED DRAWING: Figure 7

    【課題】各受光素子からの受光信号を任意の組み合わせで選択し、選択した受光信号の受光値の測定を並行して行う処理を高速化する。【解決手段】多入力多出力MUX251は、制御部21からの第1制御信号により、入力端子IN1乃至IN12の接続先を各出力端子OUT1乃至OUT4の中から設定する。多入力多出力MUX251は、制御部21からの第2制御信号により、入力端子IN1乃至IN12と接続先に設定されている出力端子OUTとの間のスイッチSWの接続状態を制御する。これにより、各受光素子202からの受光信号の入力先が、TIA261−1乃至261−4の中から設定される。本発明は、例えば、車両用のレーザレーダ装置に適用できる。【選択図】図7
