The turning point is a prism (9).

region in which a current reverses its direction of flow

The invention relates to a sensor strip comprising at least one optical waveguide (11) and a turning point.

The turning point is optically coupled to the optical waveguide (11) at a first free end of the optical waveguide (11).

The connection of the reversing region (5) to the accumulator element (7) comprises a valve device (10).

The cross-feed conveyor (5) selectively conveys the steel plate (27) between the printing area (39) and a reversing area (55) established at a side section of the printing area (39).

A reversing region (30, 31) is respectively embodied between the control nodules (9, 10), a first end (32) of a pressure compensation line (33) ending in one of the reversing regions (30, 31).

In the area of one reversing zone, the cylinder chambers are fluidically connected to a fluid capacity via a connection line.

According to the invention, the detection of light with a particularly high blue component may be achieved by the use of the inversion zone and the space charge region of a CMOS-type structure.

A control voltage is set at the gate electrode during operation to such a level that a continuous inversion zone is generated below the optionally structured gate electrode.

In the polarization reversal area, the signal electrode is disposed on one of the parallel waveguides while in the non-reversal area the signal electrode is disposed on the other parallel waveguide.

The control plate has a pilot control groove (34) which extends from a control port (29, 30) into a reversing zone (32).

A first and a second reversing region (5, 6) are formed between the first control opening (2) and the second control opening (3).

A polarization reversal area is formed on a part of an area where the light transmitted through a pair of parallel waveguides interacts with the high frequency electric signal transmitted through a signal electrode.

The reversing apparatus (9) is disposed in the reversing area (55) and turns the steel plate (27) over by rotating the steel plate (27) around the edge (141).
