Light pickup
专利汇可以提供Light pickup专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a pickup where a half mirror is needless and stability and an assembling efficiency are good, by detecting the reflection light of a wobbling light from a disc by a photo detector, which is provided near a stopping-down lens, and controlling a two-dimensional movement machanism. CONSTITUTION:The laser light from semiconductor laser 1, which is moved together with two-dimensional moving machine 9 in one body, becomes a wobbling parallel light flux by intermediate lens 2', which is wobbled by voice coil 5', and irradiates video disc 6 through stopping-down lens 10. The reflection laser light is received by photo detectors 11a and 11b, which are provided near lens 10 independently, to genetate signals according to the received focus error, and moving machine 9 is subjected to servo control. As a result, a stable tracking dependent upon the receiving light quantity without loss is performed in a constitution where no half mirror is required, and the optical system is simple and becomes easy to assemble and adjust.，下面是Light pickup专利的具体信息内容。
