Abstract

The fibre optic transmitter is of the high effect type, and involves a photo-luminescence sensor with a sensor fibre (1) with appropriate numerical aperture. Excitation light from the sensor fibre is formed on a sensor material (3) using a positive lens. This causes the formation of a luminescent area (2). By selection of the distance between the fibre and lens as greater than that between the lens and the sensor material, the fibre end surface is formed on a reduced scale. Excitation light from the sensor fibre (1) can be transformed into a parallel bunch of beams by a graded-index lens (5), and projected by a second such lens (6) on the sensor material (3). Where no lens is used, excitation light from the sensor fibre creates a luminescent area (2) of virtually the same size as the fibre end surface. The part of the luminescent light connected into the fibre is determined by a cone with an appropriate half peak angle. (Provisional Basic advised week 84/06)
