Abstract: An optical device has an optical element 21 comprising a light-emitting region 1 and a light-detecting region 4 disposed closely to each other on a common substrate 9. Returning light LR from an irradiated medium which is irradiated with light L emitted by the light-emitting region 1 is detected by the light-detecting region 4. The returning light is applied to a light-detecting region 4 at an incident angle alpha in the range of 0 DEG

Abstract: An optical device structure can be simplified and miniaturized on the whole. A fabrication of optical device can be simplified and the optical device can be improved in reliability. The optical device can increase its output, operate a light emitting light source with a reduced power and reduce a power consumption by increasing a quantity of reflected-back light to a photosensor device, i.e., a quantity of photosensed light. An optical device includes a light emitting section (1), a radiated section (2), a converging means (3) and a photosensor section (4). Light emitted from the light emitting section (1) is converged and radiated on the radiated section (2) by the converging means (3). Reflected-back light (LR) reflected from the radiated section (2) is converged and the photosensor section (4) is disposed near a confocal of the converging means (3) concerning reflected-back light from the radiated section (2). Light emitted from the light emitting section (1) is passed through a path of the same axis and photosensed by the photosensor section (4) as shown by a one-dot chain line (a) representing the optical axis before and after the emitted light is reflected by the radiated section (2).

Abstract: PURPOSE: To speed up information processing and to increase an information quantity of an optical recording medium by receiving and detecting the return light from an object of the exit light emitted from a light emitting part near a cofocal position by a light receiving part. CONSTITUTION: This focal microscope has an optical coupling element array 41 one- dimensionally arranged with plural pieces of optical coupling elements 1 on a common substrate 1 and an objective lens 46. The optical coupling elements 1 are arranged with light emitting parts and light receiving parts in proximity on the common substrate to receive and detect the return light rays from the object 47 of the exit light rays emitted from the light emitting parts near the cofocal position by the light receiving part. The light rays from the respective optical coupling elements 1 of the optical coupling element array 41 eventually focus at the different positions in the depth direction respectively to the object 47 at the time of adopting the arrangement to relatively incline the optical coupling element array 41 with the object 47. The three- dimensional light information is eventually obtd. in parallel at a high speed by relatively scanning the object 47. The light emitting parts and the light receiving parts are monolithically formed and are composed as one optical part.

Abstract: PURPOSE:To simplify the structure of a recording head by respectively evaporating a plurality of recording materials by the irradiation with heating beams to transfer them to a material to be recorded and providing a beam route altering means altering the route of the heating beam from a heating beam emitting means to allow the same to be selectively incident on any one of a plurality of the recording materials. CONSTITUTION:A plurality of recording materials 22'Y, 22M, 22C (e.g. evaporable dyes 32Y, 32M, 32C for yellow, magenta and cyan) are evaporated by the irradiation with a heating beam (e.g. laser beam L) to be transferred to a material to be recorded (e.g., printing paper 50). A beam route altering means (e.g. galvanomirror 100) altering the route of the heating beam from a heating beam emitting means (e.g. multilaser array 18) to allow the same to be selectively incident on any one of a plurality of the recording materials is provided. As a result, the heating beam emitting means can be made common to a plurality of the recording materials and a head structure containing the heating beam emitting means can be simplified and the assembling thereof becomes easy.

Abstract: PURPOSE:To attain the increasing of the light quantity of a light receiving part by making an exit light from a light emitting part pass through an coaxial path before and after it is reflected at a part to be irradiated and receiving the light at the light receiving part. CONSTITUTION:A light emitting part 1 and a light receiving part 4 are made integral on a common substrate 9, the light emitting part 1 has a semiconductor laser 8 having a horizontal resonator and a reflection mirror 7 and the light receiving part 4 is constituted of photodiodes. In the case of a constitution in which the semiconductor 8 has the horizontal resonator the exit light is reflected at the reflection mirror 7 to coincide with the path heading to the part to be irradiated 2. Then, a returned light LR heading to the light receiving part 4 is converged to the vicinity of the limit of a light diffraction and the light receiving part 4 is provided so that at least one part of a light receiving plane is positioned within the limit of the light diffraction, that is, within a position where the distance from the optical axis (a) of the exit light from the light emitting part 1 transversing the arrangement reference plane S of the light receiving plane is smaller than 1.22lambda/NA, where the wave length of the exit light from the light emitting part 1 is defined as an lambda and the numerical aperture of a converging means 3 is defined as an NA. Thus, the whole of a device is miniaturized and the light quantity of the light returned to the light receiving elements can be increased.
