摘要： Laser sources produce two light beams which are different in frequency and at least one of which is a pulse beam. The two light beams are subjected to sum frequency mixing in a non-linear optical element and a resultant sum frequency beam is applied to a specimen as an exciting pulse beam. A pulse beam separated from the sum frequency beam and synchronized therewith is detected by a photodetector. A measuring means measures a waveform of fluorescence light emitted from the specimen using an output of the photodetector as a measurement starting reference signal. According to one embodiment, the device operates in a single photon counting mode and the measuring means counts repeatedly an elapsed time from the detection of the measurement start reference signal to the detection of the fluorescence light for every divided section of the elapsed time.

摘要： A wavelength of light emitted from a semiconductor laser is shifted to a shorter wavelength with wavelength converting means and the resulting light of a shorter wavelength is applied to a sample. Upon exposure to the light of the shorter wavelength, the sample emits light of interest and its waveform is measured with measuring means. Fundamental wavelength laser light which passes through the waveform converting means is outputted therefrom in synchronism with the light of a shorter wavelength and detected by a first photodetector. The waveform of the light of interest can be measured correctly on the basis of an output signal from the first photodetector.

摘要： Light emitted from a light source module and introduced to an optical fiber is detected with a photodetector. An amplification unit amplifies an output from the photodetector. Using a piezoactuator, the light source module is subjected to reciprocal scanning by repeating one-dimensionally in the X axis direction. In this way, one-dimensional optical intensity distribution in the X-axis direction is obtained based on an output of an amplification unit obtained in accordance with the reciprocal scanning. Based on the one-dimensional optical intensity distribution in the X-axis direction, relative positions between the light source module and the optical fiber are adjusted.

摘要： Optical waveform observing apparatus including a sampling streak tube to which is applied an incident light beam having a waveform of repetitive frequency to be observed. An electron beam corresponding to the incident light beam is repetitively deflected in the streak tube, in response to a repetitive deflecting trigger signal, to sample the electron beam. The deflecting trigger signal is generated by a time sweep circuit that stepwise delays the occurrence of that signal when the sampling operation is carried out a predetermined number of times. An integration circuit integrates the output of the streak tube for the predetermined number of sampling operations for a sampling time and is then reset to begin integrating the streak tube output for the predetermined number of sampling operations for a next sampling time. The integration circuit output is digitized and displayed.

摘要： The double sweep streak camera device of the present invention includes a streak tube having a pair of first deflecting electrodes for forming a deflecting electric field in the direction of a time axis at the rear stage of a focusing electronic lens system in an image tube and a pair of second deflecting electrodes for forming a deflecting electric field substantially perpendicular to the aforementioned deflecting electric field formed by the first deflecting electrode. A DC high voltage generating unit supplies operating voltages to the streak tube and first trigger signal generating units provides a first trigger signal in synchronization with a light beam under measurement. A first deflecting voltage generating unit applies a sine wave or a ramp deflecting voltage to the first deflecting electrodes in synchronization with the first trigger signal to cause the first deflecting electrodes to form the deflecting electric field. A second trigger signal generating unit provides a second trigger signal for starting observation of the waveform of the light beam under measurement. A second deflecting voltage generating unit applies a ramp deflecting voltage which synchronizes with the second trigger signal to the second deflecting electrodes to form a deflecting electric field which is lower in frequency than the deflecting electric field formed by the first deflecting electrodes, thereby to separate observed waveforms on the phosphor screen of optical phenomena which occur successively at a high frequency. A gate voltage generating unit drives the streak tube in synchronization with the second trigger signal.

摘要： An optical feedback photodetection apparatus of the present invention achieves high-speed response while minimizing noise to obtain a high S/N ratio and a wide dynamic range. In the apparatus, on the basis of a modulated drive signal from a drive signal output circuit, a semiconductor laser outputs a light beam modulated at a frequency f.sub.0 to irradiate an object to be measured through an optical system, and the light beam reflected by the object is fed back to the semiconductor laser through the optical system. The intensity of the light beam from the semiconductor laser having an optical amplification function varies due to the return light beam. A photoconductive light-receiving device to which a modulated voltage signal at the frequency f.sub.0 from a voltage application unit is applied receives the light beam from the semiconductor laser and having an intensity varying due to the return light beam, thereby performing synchronous detection. A modulated current signal flowing through the photoconductive light-receiving device is converted to a voltage signal by a current/voltage conversion unit, and the low-frequency component of the voltage signal is extracted.
