    • A film pack having light shielding means for use in a camera employing individual film units, which light shielding means includes a pair of guide means provided on side walls of the film pack, while one surface of the film pack formed with a discharge outlet for the film units is located between the side walls, so that the light shielding and stopper member of the light shielding means for shielding the discharge outlet can be guided along the guide means so as to close or open the discharge outlet. The light shielding means further includes a light shielding plate member of resilient material held between the discharge outlet and the light shielding and stopper member for perfect shielding of outside light, which shielding plate member is adapted, by its own resilience, to allow the film unit to pass therethrough when released from the light shielding and stopper member.

    • An apparatus and method for generating a wavelength-tunable short pulse that can generate wavelength-tunable short pulsed light in the visible-light wavelength band are provided. When ultrashort pulsed light is introduced into an optical fiber (3), a wavelength-tunable ultrashort soliton pulse is generated by a nonlinear optical effect through the soliton effect and Raman scattering. When the soliton pulse has a short duration and high peak intensity, a third harmonic having one-third of the wavelength of the soliton pulsed light is generated by a third nonlinear optical effect. This third harmonic has a short wavelength in the visible light band.

    • In a distance measurement device of the invention, a light divider separates pulsed light emitted from an ultrashort pulse fiber laser into reference light A and signal light. A scanning mirror unit irradiates an object with the signal light as a division of the pulsed light and receives scattered light B, which is reflected from the object irradiated with the signal light. An optical path length adjustment unit adjusts an optical path length of the reference light A as a division of the pulsed light. A differential detector included in an interference signal generator detects the degree of interference of the reference light A having the adjusted optical path length with the scattered light B and outputs the detected degree of interference as an interference signal. A computer specifies an adjustment value set in the optical path length adjustment unit to attain a specific optical path length maximizing the interference signal and uses the specified adjustment value to compute a distance from a reference position of the scanning mirror unit to the object. The distance measurement device of the invention thus enables high-speed and highly-accurate measurement of the object.
