摘要： An image recognition apparatus includes a light source including a plurality of light emitting diodes having different wavelengths, for illuminating an object, a driver for selectively operating the light emitting diodes and adjusting the brightness thereof, an image pick-up device for photoelectrically transferring the light reflected from the object into an image signal, and an image decision device for comparing a reference image signal with the image signal obtained by the image pick-up device and then deciding whether an image corresponding to the obtained image signal is clearer than an image corresponding to the reference image signal, the image decision device making the driver sequentially operates the light emitting diodes and change the brightness thereof in such a manner that the image corresponding to the image signal is clearer than the image corresponding to the reference image signal.

摘要： A semiconductor laser device and optical pickup in which the reflectance of the side beam at a header portion will not adversely affect the characteristics of the optical pickup, and superior in productivity, and a method of fabricating such a semiconductor laser device are obtained. A reflector is attached on a side beam incident region of a leading end plane of a header mounted with a laser chip that emits a laser beam. Said side beam is one of the two side beams generated by the reflected ±first order beams and fed back through the optical system returning towards the header portion to strike the side beam incident region. The reflector reflects side beam outside the optical system.
