    Abstract: In an optical position sensor capable of detecting a direction of incidence of light and intensity, this invention contemplates to make the sensor compact by reducing the number of pixels constituting light reception sensors and reducing the light reception area. To accomplish this object, a detection element portion 10 comprises a glass substrate 22, a light shading film 24 formed on a surface of the glass substrate 22 and having mutually criss-crossing slits 24a, 24b and a light reception portion 26 fixed to the back of the glass substrate 22. Unidimensional photo-diode arrays 26X, 26Y for receiving the slit beams passing through the slits 24a, 24b respectively, and a signal processing circuit 28 for scanning the photo-diode arrays 26X, 26Y and taking out light reception signals are disposed in the light reception portion 26.

    Abstract: An optical instrument wherein an optical signal is projected on to a sensor array or sensitive medium and angular deflections of the path of the optical signal about an instrument signal source as centre appear as displacements from a datum lying in the general plane of the sensor array or sensitive medium, the instrument having an optical axis passing through said source and normal to said plane, characterized in that, to correct for the tangent law error that would otherwise arise, a correcting optical device is interposed in the signal path and has its surface receiving the signal curved, in the concave sense, about a centre lying on or intersecting the optical axis of the instrument, the curvature being of radius R, where R is greater than the distance t from said instrument signal source to the point in said curved surface that lies on said optical axis, the surface of the correcting optical device facing the sensor array being plane.
