Abstract: PROBLEM TO BE SOLVED: To provide a condensing optical encoder which is small and compact. SOLUTION: In an optical encoder 10, a polarizing device 22 divides an emission light from a laser light source 21 into a diffraction zero dimension light (main beam) L0 and diffraction plus/minus one dimension light (sub-beams) L1, L2. Those main beam L0 and sub-beams L1, L2 are collected to a scale plate 40 by an objective lens 25. A condensing position A(0) of the main beam L0 and a condensing position A(-) of the sub-beam L2 are set to be away from each other at a distance of (1+1/4)λ with the proviso that a cycle of forming of patterns of a reflection section 421 on the scale plate 40 is designated as λ. As a result, a first encode pulse signal formed based on the main beam L0 and a second encode pulse signal formed based on the sub-beams L1, L2 are in a relationship that the phases thereof are shifted 1/4 cycle with each other.  Therefore, a phase A signal and a phase B signal of which phases are shifted 1/4 cycle with each other can be obtained by utilizing a single optical unit, thereby reducing the condensing optical encoder in size.

Abstract: PURPOSE:To realize the reduction of the number of parts and the simplification of a manufacturing work process, by constituting a sensor of a single light emitter-receiver and one optical fiber other than a transducer. CONSTITUTION:A control apparatus 6 applies a timing pulse with a predetermined cycle Ta to a drive circuit 5 to allow a light emitter-receiver 4 to perform light emitting operation. Next, the exciting light from the light emitter- receiver 4 passes through an optical fiber 3 to irradiate a phosphor 2. The fluorecences LA, LS emitted from the phosphor 2 excited by said exciting light go back through the optical fiber 3 but, because the light emitting diode constituting the light emitter-receiver 4 is reversely biased corresponding to a time width Tb, only afterglow during this time is received. Next, this afterglow signal is amplified by a detection circuit 7 and subsequently integrated over the time width Tb to calculated the integral quantity of afterglow. This integral quantity of afterglow is compared with the temp. characteristic of the integral value of the quantity of afterglow preset by an operation circuit 8 to calculate the temp. of an atmosphere in which the phosphor 2 was placed and the calculated result is displayed on a display device 9.
