摘要	PURPOSE:To make a near field pattern between adjacent light-emitting regions continue while obtaining a large optical output by forming a section shaped in the direction except the direction parallel with the main light-emission direction of at least the optical output to an isolation trench. CONSTITUTION:An isolation trench 38 is shaped from one end face to the other end face so as to have a section in the direction except the direction parallel with the direction 39 of an optical outgoing axis on a substrate surface in an array-shaped light-emitting device. Since the isolation trench 38 is shaped circularly, it includes a section, which does not run parallel with the direction 39 of the optical outgoing axis. Accordingly, since the isolation trench 38 does not run parallel with the direction 39 of the optical outgoing axis between nearest light-emitting elements, light emission from the side face of the isolation trench 38 is also acquired as an optical output in the direction 39 of the optical outgoing axis at the same time as an optical output 311 from an optical outgoing end face 312 on element operation, and an optical system, focal depth of which is equalized to element length L or is larger than L, is used as an optical system employed for image formation, and also image-forming light from the side face of the isolation trench 38 as a near field pattern on an imaging face is used.
其他摘要	目的：通过形成除了与至少光输出的主光发射方向平行的方向形成截面形状的截面，使相邻的发光区域之间的近场图案连续，同时获得大的光输出到隔离沟槽。组成：隔离沟槽38从一个端面到另一个端面成形，以便在除了与基板表面上的光学出射轴的方向39平行的方向之外的方向上具有阵列形状的光 - 发射装置。由于隔离沟槽38的形状是圆形的，它包括一个截面，该截面不与光学出射轴的方向39平行。因此，由于隔离沟槽38不与最近的发光元件之间的光学出射轴的方向39平行，所以从隔离沟槽38的侧面发射的光也作为沿39方向的光学输出获得。光学输出轴与光学输出端311在光学输出端311上同时进行元件操作，光学系统的焦深与元件长度L相等或大于L，用作光学系统用于图像形成的系统，以及来自隔离沟槽38的侧面的成像光作为成像面上的近场图案被使用。
