    • PURPOSE:To form an object having the same shape as the shape of a target object from the target object by irradiating slit light to the outside circumference at one section of the target object, picking up the image thereof, measuring one sectional shape thereof, manufacturing a template conforming thereto and superposing successively such templates. CONSTITUTION:Slit light such as laser or the like is irradiated from a slit irradiating device 1 to the outside circumference at one section of a target object 5 having a crest shape, etc. and the light image 6 by said slit light is picked up by a two-dimensional image pickup device such as a camera for TV, etc. having the optical axis intersecting orthogonally with the plane of the slit light. The one sectional shape is measured from the image obtd. in such a way as the coordinate point (Xi, Yi) of the X-Y coordinate axial system. A template having the same thickness DELTAh as the slit light is manufactured on the basis from the measured value in accordance with the above- mentioned sectional shape. The device 1 is moved stepwise along a stanchion 3 by a slide 2 and the above-mentioned templates are manufactured over the entire length of the object 5. Such templates are successively supposed and the object having the same shape as the shape of the object 5 is thus easily obtd. at a high speed from said object.

    • PURPOSE:To detect angular displacement with high accuracy by detecting the reflected light of laser light projected on a group of pits provided at intervals in the circumferential direction of an optical disk by a couple of photodetecting elements which photodetect light from pits shifting in the circumferential direction. CONSTITUTION:Plural pits 6 are provided along a track 5 of the optical disk 3 which is fitted to a rotary body and rotates together with the rotary body at equal intervals l1 to equal length l2 and width d1. Laser light from a light source 8 is reflected by the optical disk 3 and made incident on photodetecting elements 12 and 13 through a lens 9, a half-mirror 10, and a lens 11. The photodetecting elements 12 and 13 photodetect reflected light from pits 6 at positions shifting on the track 5 in the circumferential direction. Variation in the output levels of the photodetecting elements 12 and 13 is photodetected to find the rotating speed and rotating direction of the optical disk 3. Consequently, the measurement accuracy is improved by the simple device.
