Abstract: A first tunable wavelength pulse light source (22) is driven by a reference signal to emit a first optical pulse. An optical demultiplexer (24) demultiplexes a first optical pulse emitted from the first pulse light source (22) into a reference optical pulse and an incident optical pulse to be sent into an object to be measured. An optical multiplexer (26) multiplexes the reference optical pulse and an outgoing optical pulse passing through the object to output multiplexed light. A second pulse light source (23) generates a second optical pulse which is synchronous with the first optical pulse and delays a predetermined time for each period of the first optical pulse. A sampling unit (27, 27a, 27b) receives the multiplexed light and the second optical pulse to obtain an optical pulse train signal proportional to the intensity of the multiplexed light obtained in synchronism with the second optical pulse. From the optical pulse train signal from the sampling unit (27, 27a, 27b), a signal processor (37) obtains an envelope formed by peaks of individual optical pulses forming the optical pulse train. The wavelength dispersion of the object is obtained by measuring the delay time of the outgoing optical pulse passing through the object on the basis of intervals between the peaks of the envelope.

Abstract: A delay time measurement apparatus for an optical element includes a pulse light source (42), wavelength setting unit (41), optical power divider (44), optical delay unit (48), controller (52), and detector (46, 53). The pulse light source (42) can vary the wavelength of light to be output, and outputs an optical pulse having a predetermined repetition period. The wavelength setting unit (42) sets the wavelength of light to be output from the pulse light source. The optical power divider (44) divides the optical pulse output from the pulse light source into a first optical pulse and a second optical pulse to be input to an optical element as the object to be measured. The optical delay unit (48) can vary the spatial optical path length along which the first optical pulse divided by the optical power divider travels. The controller (52) changes the spatial optical path length of the optical delay unit. The detector (46, 53) receives a measurement optical pulse output from the optical element as the object to be measured, and a reference optical pulse output from the optical delay unit, and detects the delay time of light that has passed through the optical element as the object to be measured from a change in spatial optical path length required for superposing the measurement and reference optical pulses on each other.
