    • PROBLEM TO BE SOLVED: To obtain a speckle removing light source that can remove speckle by using a laser beam, the wavelength of which is changed temporally.
      SOLUTION: The speckle removing light source includes: a light source for output of a laser beam, the vertical mode of which is a single mode; a light frequency modulating means for changing the wavelength of a laser beam; a multimode optical fiber, which is long in its longitudinal direction and bent; and at least one or more condenser lenses for guiding a laser beam to the optical fiber. The condenser lens converts the condensing size of a laser beam into the size substantially equal to the size of the core diameter of the optical fiber, and also converts the number of aperture of the laser beam into the number substantially equal to the number of aperture that enables the transmission of the optical fiber. In the optical fiber, at least two or more modes are provided for light, light beams to the highest order mode from a basic mode, which are different from each other in transmission time amplified by the number of reflections within the optical fiber, are superposed in a space distribution at the emission end face, and a part including an end face, from which at least the light of the optical fiber is output, and the core outside diameter shape of a cross-section are approximately polygonal.

    • PURPOSE:To completely prevent the influence of the fluctuation of a power supply voltage of a PWM wave output type D/A converter by determining the crest value of an output pulse wave of the D/A converter by the product of a current value of a variable current source and a conversion rate of a current/voltage converter. CONSTITUTION:The pulse wave being the output signal of a PWM wave output type D/A converter 1 operates only as timing information for opening and closing a current switch 5, and the crest value of the output pulse wave of a D/A converter is determined by the product of an output current I0 of a variable current source and a current/voltage conversion rate Z0 of a current/ voltage converter 6, that is, I0/Z0. Accordingly, the influence of fluctuation of a power supply voltage 9 of the PWM wave output type D/A converter 1 mixed into the output pulse wave does not produce distortion and noise.

    • PROBLEM TO BE SOLVED: To provide an image evaluation apparatus capable of quantitatively evaluating a blur amount in a viewed state by a human being.
      SOLUTION: The image evaluation apparatus is configured such that a position detection type photodetector 22 receives the light of an image and picks up the image when the image using a finite element for a light source is formed and the image is projected onto the position detection type photodetector 22 and an image evaluation section 25 evaluates the blur amount of the image picked up by the position detection type photodetector 22. Thus, when e.g., the array of finite elements like a projector displays pixels, the image evaluation apparatus can quantitatively evaluate the blur amount in the viewed state by the human being.
