A signal processing apparatus includes a differential processing unit to differentiate a reflection signal corresponding to a pulse measurement beam that is periodically scanned in a polarized manner; an arithmetic unit to obtain, with a rising time of a f...

A distance detection induction device comprises a housing, a condensing lens, a circuit board bearing multiple electronic components, an infrared light emitting means for emitting the infrared light, and a light receiving means for receiving and sensing th...

The device includes a transmitter and a spaced-apart receiver. The transmitter emits at least two measurement beams which scan a surface in a defined relation to each other. The receiver receives the measurement beams resolved w.r.t. time, so that the time...
