Abstract: 1412278 Measuring non-electrically variables electrically: Two-wire telemetry DANFOSS AS 1 Dec 1972 [3 Dec 1971] 55544/72 Headings G1N and G1U In a multiplex electric circuit a number of  sensors P 0  P 1  P 2  P 3  are associated with signal generators M 0  M 1  M 2  M 3  which provide current signals on the lines 4, 5, dependent on the values of the parameters being sensed, the lines 4 being connected to one pole of a source SF, and the other line 5 being selectively connected by switches K to the other pole through a load Z, which therefore has developed across it a voltage dependent on the value of the selected sensor. As shown P 0  is a switch, P 1  a temperative sensitive resistor, P 2  a variable capacitance pressure transducer. The switches may be contact switches, or transistors addressed through their bases Fig. 2 (not shown). The transistor switches may be arranged to accommodate a large number of sensors. To permit faster scanning, switching diodes, which allow the current transmitters to remain conducting continuously, may replace the transitors.

Real images of the holographically recorded objects are reconstructed by illuminating the hologram with a coherent reconstruction beam, and positioning adjacent the hologram and read-out base member, of similar construction to the surface recording base member 16, to reproduce the reconstructed image. If only one read-out base member is used it is movable to pick-up a desired reconstructed image. The light sensitive surface of read-out member may have to be developed to make the image visible. However of desired the lightsensitive surface of base member 16 may be photo-chromic, and that of read-out member may be fluoroscent. The objects may be pages of some documents and they may be recorded on the base member 16 in reduced size. The initial record on base member 16 may be effected, using any electromagnetic or sound waves and may use any well known imaging or copying process. In one construction of the record base member 16 the coating 20 unexposed has the same refractive index as the base 18. Alternatively the unexposed coating 20 may have a different refractive index than the base 18 which changes toward that of the base on exposure. To prevent cross-talk the opposite side of the base may be coated with a light reflector of a material of lower refractive index. In a further embodiment the images recorded on base member 16 may themselves be holograms. Colour images may be recorded and reconstructed using coherent light sources of three frequencies.
