A method of producing an amplitude- or intensity-modulated fiber-optical reflection sensor comprising an optical fiber and a light-reflecting surface, the optical fiber being arranged to transmit light to the light-reflecting surface, to receive the reflected light from the surface and to conduct the light for further processing, and the optical fiber having an end with an end face spaced a predetermined distance from the light-reflecting surface, which method comprises the steps of introducing the optical fiber end in a through bore of a block having an end face, placing a hardenable adhesive mass in the through bore around the optical fiber end to fix the optical fiber end in the block, permitting the hardenable adhesive mass to harden, and together grinding the end faces of the optical fiber end and of the block. The end face of the block may be concavely ground and a membrane may span the concavely ground end face and carry the light-reflecting surface.
