    • A confocal scanning imaging device for viewing an object includes an array of independently addressable microlasers and an array of detectors for detecting light from an object to which light from the microlasers has been directed. The array of microlasers and the array of detectors are combined into a single array, such as on a single chip, and in a pattern constructed and arranged so that different detectors are adjacent to each microlaser so that light from an illuminated object may be directed back to the vicinity of the illuminating microlaser and be detected by the adjacent detector(s). An optical arrangement directs light generated by the microlasers onto an object and directs light from an object so illuminated onto detectors adjacent to the illuminating microlaser. The optical arrangement includes a bilens and a matching lens system including two objective lenses. A microlens collimates light generated by the microlasers.
    • 用于观看物体的共焦扫描成像装置包括可独立寻址的微型激光器的阵列和用于检测来自微型激光器的光的物体的光的检测器阵列。 微阵列和检测器阵列被组合成单个阵列,例如在单个芯片上,并且以构造和布置的图案组合,使得不同的检测器与每个微激光器相邻,使得来自被照射物体的光可以被引导回 到照明微型激光器的附近,并由相邻的检测器检测。 光学装置将由微型激光器产生的光引导到物体上并将来自被照射到物体上的光引导到与照明微激光器相邻的检测器上。 光学装置包括双相和包括两个物镜的匹配透镜系统。 微透镜校准微量元件产生的光。

    • A system discriminates an in-focus image from an out-of-focus image so as to reduce both systematic and statistical errors in a measurement of the in-focus image. The system produces a probe beam (p22B) and a reference beam (R22B) from a point source (10), and antisymmetric spatial properties are produced in the reference beam (R22B). An in-focus return probe beam (P32A) is produced as a result of directing a probe beam (P22B) into an in-focus image point (28), and antisymmetric spatial properties are produced in the in-focus return probe beam (P32B). The reference beam (R32C) is interfered with a beam from an out-of-focus image point (58), and the reference beam (R32C) is interfered with the in-focus return beam (P32C). The reference beam (R32D) is detected by a single-pixel detector (114) as a square of an amplitude of the reference beam (R32D), and the in-focus return probe beam (P32D) is detected by the detector (114) as an interference term between a return reference beam (R32D) and the in-focus return probe beam (P32D). An amplitude of an interference term between an amplitude of the out-of-focus image beam (B52D) and an amplitude of the return reference beam (R32D) is substantially reduced, resulting in reducing both systematic and statistical errors in data produced by the detector (114). In the described embodiment, the beam from the out-of-focus image point (58) is an out-of-focus return probe beam (B52D).
    • 系统鉴别对焦图像与离焦图像,以减少对焦图像的测量中的系统误差和统计误差。 系统从点源(10)产生探测光束(p22B)和参考光束(R22B),并且在参考光束(R22B)中产生反对称空间特性。 通过将探测光束(P22B)引导到对焦图像点(28)中,产生对焦返回探测光束(P32A),并且在对焦返回探测光束(P32B)中产生反对称空间特性 )。 参考光束(R32C)会干扰来自离焦图像点(58)的光束,参考光束(R32C)会干扰对焦返回光束(P32C)。 参考光束(R32D)由单像素检测器(114)检测为参考光束(R32D)的振幅的平方,并且检测器(114)检测对焦返回探测光束(P32D) 作为返回参考光束(R32D)和对焦返回探测光束(P32D)之间的干涉项。 离焦图像光束(B52D)的振幅与返回参考光束(R32D)的幅度之间的干涉项的幅度大大降低,导致减少由检测器产生的数据中的系统误差和统计误差 (114)。 在所描述的实施例中,来自离焦图像点(58)的光束是离焦返回探测光束(B52D)。
