摘要： A real-time range finder comprising light sources 12 and 13 for composing a plurality of light beams having different wavelength characteristics and sweeping the traveling direction of the composite light and either the wavelength or intensity of the light; a plurality of optical filters 15 and 16 for introducing light beams corresponding to wavelength characteristics of the plural light beams to charge-coupled devices; the charge coupled devices 20 and 21 arranged in accordance with the plural optical filters, respectively; a distance calculation unit 26 for calculating, from pixel values of image data obtained from the charge-coupled devices and from the sweep start time of the light sources, a time at which light is incident on the pixels, and calculating a distance to the subject. With such this finder, it is possible to measure a distance at real-time with a simple structure while using normal photo sensors which are not provided with time measurement functions.
