摘要： A time difference measuring device can accurately measure a time difference between two pulse signals generated with a predetermined time difference by measuring the two pulse signals by one measurement. The time difference measuring device measures a time difference between a start signal (M1) and a stop signal (M2). The device has a reference signal generation unit (41) for generating two reference signals (S1, S2) having a π/2 phase difference. According to corresponding amplitude values (A11, A12) and (A21, A22) of the reference signals (S1, S2) at each generation timing of the start signal (M1) and the stop signal (M2), a phase difference detection unit (42) calculates a phase difference Δθ (=θstop−θstart) between the generation timings of the pulse signals (M1, M2). According to the detected phase difference Δθ and the cycle (Ts) of the reference signals (S1; S2), a time difference calculation unit (44) calculates the generation time difference Δt between the pulse signals (m1, M2).

摘要： The present invention relates particularly to a laser irradiation light detecting device having detecting means for receiving a reflected light pencil of a laser light pencil applied from a laser irradiating device provided with a non-linear optical medium for generating a second harmonic. A laser light source pumps an optical resonator and a pulse driving means drives the laser light source. An irradiating means applies a pencil of pulse laser light produced from a laser oscillating device to a target device. A detecting means detects a light pencil reflected from the target device. An arithmetic processing means executes predetermined operations, based on the signal detected by the detecting means. The detecting means detects the reflected light pencil of the pulse laser light pencil in synchronism with a period T of a driving pulse of the pulse driving means.
