Koaxiell elektrooptisk avståndsmätare |
摘要 |
A coaxial electro-optical distance meter has optical elements on light transmitting side which are located behind an objective lens such that light from a light transmitting member is reflected from a first reflecting surface disposed adjacent to an optical axis of the objective lens. The reflected light is emitted as transmitted light to a reflecting member disposed ahead of the objective lens. Optical elements on light receiving side are arranged such that received light from the reflecting member is reflected from a second reflecting surface disposed behind the first reflecting surface for guiding it to a light receiving member disposed beside the optical axis. The first reflecting surface is disposed such that the optical axis is positioned inside a luminous flux of the transmitted light. The cross section of the luminous flux of the transmitted light is reformed into a point-asymmetrical shape by a diaphragm plate having an opening therein for passing therethrough light from the light transmitting member. |
