<p>PURPOSE: To provide a compact, inexpensive infrared detector having an excel lent detecting accuracy of infrared rays. CONSTITUTION: A plurality of infrared detecting elements 3 are aligned and formed two-dimensionally. An infrared lens condenses the infrared rays from a heat source to be detected in a detecting region and guides the infrared rays to the corresponding elements 3. In this infrared detector having these parts, the shapes of the elements 3 at the peripheral part are deformed in conformity with corresponding infrared images 6b, 6c and 6d, the areas are reduced and the interval between the centers of the peripheral elements 3 is narrowed when the shaped of the infrared images 6a, 6b, 6c and 6d of the same heat source are deformed as the images are separated from the central part, or the areas of the images are reduced, or the center of the image is deviated from the center of the corresponding element 3 in the direction of the central part, caused by the optical aberration of the lens.</p> |
