Abstract

PURPOSE:To facilitate to obtain sufficient optical and electrical isolation between light receiving elements by generating diffracted light in two symmetrical directions with respect to an incident optical axis to a light deflecting element by using Raman- Nath diffraction. CONSTITUTION:A lens shaped medium 2 is provided in a light path of incident light from a laser light source 1. In an outgoing light path from said medium 2, a a light deflecting element 8 which generates the diffracted light in two symmetrical directions with respect to the outgoing light axis is provided. A lens shaped medium 5, which performs Fourier transformation of the outgoing diffracted light from said light deflecting element 8, is provided. In the outgoing light path from said medium 5, two groups light receiving elements 9 and 10 are provided, and receives the outgoing diffracted light.
