摘要： An optical apparatus which detects a visual axis using plural reflected images of a light source includes an observation device with which an observer observes an object. An image sensor is provided for generating a signal and response to an image. Optical structure is provided for forming a plurality of reflected light source images on the image sensor by reflection of light from the eye of the observer. The optical structure includes (1) an illumination assembly for projecting a light beam from at least one light source to the eye of the observer, and (2) a convergence component having at least one convergent lens for converging the light beam reflected from the eye of the observer, to produce the plurality of reflected light source images. The optical structure includes at least two light sources and/or two convergent lenses. An electrical circuit is coupled to the image sensor for generating (1) information relating to a working distance between the plurality of reflected light source images reflected from the eye, and (2) information relating to the reflected image of a front eye part, to generate information relating to a direction of the visual axis of the eye.

摘要： In the disclosed distance measuring arrangement, a light projector turns on and off to illuminate an object over the ambient light during projection periods when light is projected and during space periods when light is not projected. The reflected light is detected as a function of distance by integrating projection signals representing light reflected during projection periods, integrating space signals representing light during reflected space periods, subtracting the integration space signals from the projection signals, and extracting measurements based on the subtractions. Compensation for change in ambient light between periods is obtained by changing the timing of the integrations and extractions from concidence with the projections and space periods.

摘要： In the disclosed distance measuring device a light source projects light on an object to be photographed. A photo-electric converter for receiving light reflected from the object includes at least one photo-electric converting portion whose electric charge varies according to the quantity of light incident thereon. A control includes a first electric charge store which stores an electric charge produced at the photo-electric converting portion while the light is projected from the light source, a second electric charge store which stores an electric charge produced at the photo-electric converting portion while light is not projected from the light source, and a detector which detects at least one of the amounts of electric charge stored at the first and second electric charge stores. The control varies the quantity of light projected by the light source on the basis of the result detected by the detector.

摘要： In the disclosed photo-electric conversion device, a light source repetitiously emits light and a photo-electric converter receives reflected light originally generated by the source and ambient light. A first store stores the output of the photo-electric converter when the light source emits light and a second store stores data from the photo-electric converter when the source does not emit light. A gate transfers the output from the converter to the first and second stores. A pulse generator controls the gate for transferring the converter output to the first store and the second store during every light emitting cycle of the light source.
