Abstract
The invention relates to an optical exploration device, particularly for the detection of the blind spot of a vehicle, comprising first passive thermal infrared detection means (2) of the thermopile variety, for example, having a sensitivity range within a first wavelength interval (1), second detection means (3) used to measure direct or indirect solar energy (5) within a second wavelength interval (12), characterized in that the first and second (12) wavelength intervals partially overlap, and in that the first (2) and second (3) detection means are disposed and are oriented in a relative manner in order to successively or simultaneously sight the same are of detection (Z). The invention also relates to a vehicle comprising said device.
