摘要： A camera flash comprises a light guide (9) arranged to extract light at least through one surface; and one or more light sources (8) arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) (8) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimising loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module (19) of a mobile telephone camera.

摘要： For controlling a wavelength of laser light of a wavelength-variable laser (step S0), an optical system or a hologram recording medium is moved (step S1) to attain a state in which a light beam enters a wavelength control pattern. Reference light that is the laser light is applied to the wavelength control pattern (step S2). Then, a light receiving element observes reproduction light from the wavelength control pattern (step S3). A wavelength of the reference light that is the laser light is minutely changed. A quantity of the reproduction light changes with the wavelength. The quantity of the reproduction light is monitored to obtain a specific wavelength λ 0 (a rotation angle of a diffraction grating 52) maximizing the quantity of the reproduction light (step S4). The wavelength of the laser light of the wavelength-variable laser light source is adjusted (step S5).
