摘要 |
Electro-optical distance measuring apparatus has a light emitting element for producing a modulated light which is projected through a condenser lens and an objective lens. Between the condenser and objective lenses, there is provided a light guide device which comprises a first optical fiber bundle adjacent to the objective lens and a second optical fiber bundle adjacent to the condenser lens. The first and second optical fiber bundles are in end-to-end relationship and the first bundle has a diameter smaller than that of the second bundle.
