Abstract
PURPOSE: To increase the accuracy of distance measurement, by providing the cylindrical element to average the distribution of amplitude toward the direction orthogonal to the base line of the image formed on the photo detection element, with the image formation systems of two apart by the distance of base line.
CONSTITUTION: The optical system to be equipped to actual camera is shown in diagram. The reference image is formed on the element train 11 with the reflection mirror 6, image forming lens 8, and reflection prism 10, and compared image is formed on the element train 11 with the reflection mirror 7, image forming lens 9 and prism 10. One cylindrical lens 12 is provided with the two systems and light is incident through it. With this constitution, the image forming systems of two can be adjacent, the length of the photo detection element train can be required minimum, and even for the distance measurement such as object having the change in the luminance toward Z, and even for the shift toward Z between the reference image and compared image, the same part is present in the compared output with the reference output to enable distance measurement.
