Title: Device for detecting position to be irradiated with light beam
Inventor: KISHIDA YOSHIHIRO
IPC: G02B26/10
Filed: 1989-08-07
Abstract: PURPOSE:To accurately detect the position to be irradiated with a light beam to be scanned by constituting the device in such a manner that at least one light beam of the light beams bisected at the time of scanning with the light beam is made incident at all times to any of the photodetectors of two arrays of the photodetector arrays disposed zigzag. CONSTITUTION:The respective photodetectors 30b are disposed zigzag along the traveling route of the light beams in such a manner as not to generate spacings between the effective photodetecting regions 30c of plural pieces of the photodetectors 30b which receive the light beams. At least one light beam of the two light beams supplied by a light beam splitting means is, therefore, received by any of the photodetectors 30b of two arrays of the photodetector arrays disposed zigzag. The influence of the blind zone of a photodetector 30 is averted without using a means for lowering the quantity of the light beams, such as scattering light and the position to be irradiated with the light beams is accurately detected.

Title: Optical element for light control
Inventor: SATO YOSHIAKI
IPC: H01S3/06
Filed: 1989-08-07
Abstract: PURPOSE:To make effective use of the high-speed signal characteristics of light and the interface of light by controlling the switching of a light signal with a light signal by using an optical amplifier. CONSTITUTION:The control signal light is inputted in superposition on the signal light to be controlled by utilizing the input/output characteristics of the optical amplifier 1, by which the operation point of the optical amplifier 1 is moved to a saturation region and the gain is lowered. Namely, the input saturation state is attained at a certain value or above and the gain of the optical amplifier 1 decreases when the level of the light signal lambda2 inputted to the optical amplifier 1 increases. The operation point of the optical amplifier 1 moves to B and the gain decreases if the control signal light lambda is inputted to the optical amplifier 1 which operates at the operation point A with respect to the signal light to be controlled by using the transition to the input saturation state is used in such a manner. The control signal light lambda 1 is removed from the output light lambda2 of the optical amplifier 1 in this way and only the signal light to be controlled lowered in the level is taken out. The utilization of this element as the switching element is thus possible.

Abstract: PROBLEM TO BE SOLVED: To obtain a stable RF signal by eliminating a mechanical positional error between a photodetector and a measuring spot due to deformation in an optical disk. SOLUTION: An anamorphic prism 4 makes a laser beam through a collimate lens 3 of a circle. A grating 5 separates the laser beam to at least three pieces of luminous flux components. A half mirror 10 separates return light from the optical disk 20 converged by a condenser lens 9 onto an RF signal system optical path 11 and a servo signal system optical path 15. A concave lens 12 enlarges the return light on the RF signal system optical path 11. A slit 13 eliminates ±1st-order light among the return light enlarged by the concave lens 12. The photodetector 14 for an RF signal receives zero-order light transmitting through the slit 13. The photodetector 17 for a servo signal receives the zero-order light and the ±1st-order light led by a multi-lens 16.
