Device for optically measuring distance

In a device 100 for measuring distance, a signal generating circuit 20 generates a driving signal. The driving signal is serially modulated in phase into at least three states. The signal generating circuit 20 further generates reference signals having frequencies the same as the driving signal. A l...
