Abstract
An optical pulse observing device enables the clear observation of indirect laser light of pulse laser light. The optical pulse observing device to be used by a user for observing pulse illumination light directly or indirectly, includes an optical shutter means that operates for alternate opening and closing in synchronism with periodic pulses of the pulse laser light so as to open only during the duration of pulses of the pulse laser light to pass pulse laser light and external light.
Claims5
An optical pulse observing device to be used by a user to observe pulse illuminating light directly or indirectly, comprising an optical shutter means that operates for alternate opening and closing in synchronism with periodic pulses of the pulse illuminating light at a frequency different from that of the periodic pulses of the pulse illuminating light so as to open to pass pulse illuminating light and external light.
