Quadrant light detector |
| abstract |
A quadrant light detector (10) that employs the concept of constructed occlusion to improve its accuracy and by incorporating baffles (28) within the design to improve its detection response to incoming light (11) having an incidence angle near the horizon, and to divide a diffusely reflective cavity (16) into quadrants. The quadrant detector (10) is able to determine the direction, or azimuth and elevation, to the light source anywhere within a sector of a hemisphere or a sphere. |
