摘要： Disclosed is a reflective encoder which is capable of measuring movement amount and detecting movement direction by using one emergent light beam, and achieving high reliability and miniaturization through a simple structure. In the reflective encoder, a light beam emitted by a laser oscillator is caused to be incident on a reflective diffraction grating disposed on a side of a scale, and diffracted light beams reflected by the reflective diffraction grating are received by light receiving elements. An interference optical system is provided between the light receiving elements and the reflective diffraction grating. An optical system is thus constructed to measure movement amount and detect movement direction by using only one emergent light beam.

摘要： An encoder includes a semiconductor laser capable of emitting two coherent light beams from two end faces thereof, respectively. The end faces of the semiconductor laser are arranged such that the coherent light beams intersect each other. The two coherent light beams emitted from the end faces of the semiconductor laser are incident on a scale having a plurality of gratings. The two coherent light beams are diffracted by the gratings, resulting in two diffracted light beams. The two diffracted light beams interfere with each other, and the intensity of the resultant interference light beam is detected by a detector. In response to this detection, the detector produces a signal corresponding to the intensity change which is proportional to the relative moving distance between the detector and the scale.

摘要： A micro optical head, for optically reading and/or writing digital data on a recording medium in which digital data 1 and 0, corresponding to a high reflection factor and a low reflection factor, is composed of a self-coupled semiconductor laser located close to the recording medium. A bias current of the laser is determined so that it is smaller than a first threshold current, in which the medium has a low reflection factor, and is higher than a second threshold current, in which the medium has a high reflection factor. Output light of the laser is either strong stimulated emission light, corresponding to the high reflection factor, or weak spontaneous emission light, corresponding to the low reflection factor. The present head is carried on a flying slider with a spacing length less than several .mu.m which provides a small beam spot of about 1 .mu.m, and has an excellent signal to noise ratio. A photodetector for sensing the output of the laser may be carried on the same semiconductor substrate as that of the laser.

摘要： The present invention provides a noninvasive alcohol sensor that measures ethanol concentration with high accuracy by suppressing error dependent on glucose concentration. An alcohol sensor 10 includes first light-emitting means 21, second light-emitting means 22 and third light-emitting means 23. The first light-emitting means 21 radiates light having a wavelength of 1185 nm. This wavelength of 1185 nm is a wavelength at which the light absorbance of water and the light absorbance of ethanol are equal. The second light-emitting means 22 radiates light having a wavelength of 1710 nm. The third light-emitting means 23 radiates light having a wavelength of 1750 nm. Light detection means 30 detects the intensity of each light, and control means 60 calculates ethanol concentration based on the detected light intensity.
