摘要： Whether or not an object is present, the surface state of the object, the material constituting the object and the presence of scattering bodies are discriminated through a simple arrangement which includes a light-emitting element for projecting light upon an object to be sensed, and a polarization beam splitter upon which light reflected from the object (or light transmitted through or scattered from the object) impinges. Reflected light from the polarization beam splitter is received by a first light-receiving element, and transmitted light from the polarization beam splitter is received by a second light-receiving element. The aforesaid discrimination is performed on the basis of the value of S/P, S-P, S-kP or (S-P)/(S+P), where S and P represent light-reception signals from the first and second light-receiving elements, and k is a constant.

摘要： This invention improves the use efficiency of light emitted by a solid light emitter such as a light emitting diode, and realizes a desired directional pattern. On a front boundary surface of a mold resin 13 sealing a light emitter 12, there are formed a direct emission region 18 for emitting the light from the light emitter 12 and a total reflection region 19 for totally reflecting the light from the light emitter 12. The direct emission region 18 is convex lens-shaped. A light reflecting portion 20 having a concave mirror shape is disposed on a rear wall of the mold resin 13. A part of light emitted from the light emitter 12 is emitted forward by receiving an optical lens action when it passes through the direct emission region 18. Another part of the light emitted by from the light emitter 12 is totally reflected by the total reflection region 19, and is reflected by the light reflecting portion 20, and emitted forward from the total reflection region 19.

摘要： A light emission device includes a light emitter, a light reflection member, and a resin sealing the light emitter by covering the light reflection member and the light emitter, in which light deviated from a predetermined front region in the light emitted from the light emitter is totally reflected by a boundary surface of the resin to be forwardly emitted by the light reflection member, and the emitter is thermally contacted with the reflection member to dissipate the heat generated from the light emitter.

摘要： An optical read/write head for a magnetic-optic recording and reproducing unit having a beam splitter placed between a collimator lens and an objective lens. The optical path of the beam reflected by a recording disk is bent by the beam splitter and the beam strikes a polarizing beam splitter. The polarizing beam splitter splits the reflected beam into P and S polarized components whose optical axes form n angel of less than 90.degree.. The rays of the P and S polarized components strike respective light detecting elements and which are co-arranged on substantially the same surface.

摘要： On a front wall of a mold resin (13) sealing a light emitter (12), a direct emission region (18), through which the light emitted from the light emitter (12) directly passes to the outside, and a total reflection region (19), by which the light emitted from the light emitter (12) is totally reflected, are formed. The direct emission region (18) is formed into a shape of a convex lens. A light reflection portion (20) which is made of a concave mirror is provided on the rear face of the mold resin (13). When a part of the light emitted from the light emitter (12) passes through the direct emission region (18), it is affected by the lens to be emitted to the front direction. After another part of the light emitted from the light emitter (12) is totally reflected by the total reflection region (19), it is reflected by the light reflection portion (20) to be emitted to the front direction through the total reflection region (19).
