When a recording starting point of a color photosensitive material reaches a position on which light beams are focused by a condenser lens and a reflecting mirror, a light beam is emitted from a red organic EL element of a light source by a controller, and red image data corresponding to a plurality of lines is transferred to a DMD. In accordance with the image data, on-off control of micromirrors of the DMD is carried out, and the red light beam emitted from the light source is made incident on the DMD. When the micromirrors are on, the incident light beam is reflected toward the reflecting mirror. The light beam is focused onto a recording surface of the color photosensitive material by the condenser lens and the reflecting mirror, and red exposure is carried out. Subsequently, green exposure and blue exposure are carried out in the same way.

A system for imaging high speed moving objects, for example, using a scanning beam and beam delivery optics with fast signal processing. It can allow for vocal fold imaging at up to or exceeding approximately 1000 frames per second with grayscale resolution as high as about 100 micrometers or higher and up to about a 12.4 mm square or larger viewing area. The invention can provide imaging of vocal fold vibration that correlates completely with a synchronously-acquired acoustic voice signal. This can enable physicians, voice therapists and research scientists to understand the consequences of abnormal laryngeal dynamics, rather than being limited to simply observing the dynamics. Further, the application of laser technology will allow for accurate measurements of dimension. This can objectify examination findings and treatment outcomes measurement, helping to overcome the serious limitations of current perceptual-based judgments.

In an optical disk recording device for projecting a recording light beam onto an optical disk to form 3T-11T pits in a land of the optical disk, timing to sample and hold a reflected light detection signal for tracking servo control is delayed behind timing to sample and hold the reflected light detection signal for wobble signal detection.

Such arrangements permit appropriate recording, even at high recording speeds, irrespective of residual optical axis deviations.
