Abstract: An optical sensor includes a light transmitter for transmitting pulsed light signals and a light receiver for receiving them. In order to suppress the effects of interfering noise light, the light signals are transmitted according to a specified pattern including pulses in packages separated from each other by a specified interval, the pulses within each of the packages following one another with a specified carrier frequency. Groups each including two or more such pulse packages may be employed. The light receiver converts a received light signal into an electrical signal and directly thereafter passes the electrical signal through a bandpass filter with a pass band including this carrier frequency.
