As shown for use on a forehead, three different thermochromic liquid crystal layers clear at 34.5 DEG C, 36 DEG C and 45 DEG C over a black backing layer. Above 34.5 DEG C 'N' clears to show black on a green area 8. At 36 DEG C, 'F' and area 11 remain green while area 10 is black. At 45 DEG C, area 14 clears to leave 'F+' green. In a room thermometer, Fig 5 (not shown) the black backing layer is uncovered gradually in thirteen steps to represent a rising black line from a bulb area. <IMAGE>

Abstract: The sensor comprises a sensing loop 5 using an optical fiber which effectively performs a single polarization when bent, both end portions of the sensing loop being disposed with the principal axes of polarization thereof orthogonal to each other and the end portions being joined by an evanescent wave coupling to form a ring interferometer, a device 1, 2 for introducing to an input end of the interferometer a linearly polarized light at a bearing of 45 degrees relative to the principal axis of polarization of the interferometer, and a retardation measuring system 6, 7, 8 provided at an output end of the interferometer for picking up an electrical output proportional to a rotational angular velocity applied to the interferometer. When the linearly polarized light is introduced to the input end of the coupling portion of the ring interferometer at a bearing of 45 degrees with respect to the principal axis of polarization of the interferometer, the light is branched into two polarized light beams running through the sensing loop, one clockwise and the other counterclockwise. The polarized light beams are recombined with each other, to be input to the retardation measuring system from which an electrical output proportional to the rotational angular velocity applied to the interferometer is picked up.
