Document Type and Number:
Japanese Patent JP3242116
Kind Code:
B2
Abstract:
A sensor for determining a one-dimensional component of the angular orientation of a radiation source relative to the sensor has a radiation sensitive element which produces an electrical signal representative of radiation incidence upon the element. A radiation-opaque mask is mounted between the element and the radiation source. A first plurality of parallel slit apertures are provided in the mask. The slits are spaced relative to one another, and the element is aligned relative to the mask, such that radiation emitted by the source through at least one of the slits is simultaneously incident upon at least two independent radiation-sensitive points on the element while the source is within an intended operational range of the sensor; and, the points are displaced from the one slit by different distances.
