Claim 6:
7. The laser radar according to claim 1,
wherein the counter comprises a first counter configured to count a first counter value showing the number of the clock signals and a second counter configured to count, at a different timing from the count of the first counter, a second counter value showing the number of the clock signals,
the laser radar further comprises a selection unit configured to select one of the first counter value and the second counter value as a third counter value based on a threshold assigned to the number of transmission stages, the threshold avoiding a reception timing of the reflected light from overlapping the signal edges of the clock signal, and
the time calculation unit calculates the round trip time of the pulse laser light on the basis of the third counter value adopted instead of the counter value, the constant period, the number of transmission stages calculated, and the specified delay time.
