Document Type and Number:
Japanese Patent JP7367577
Kind Code:
B2
Abstract:
To enable a pair of light projection/reception systems to range-find a broad range in a TOF method range-finding device.SOLUTION: An optical device is provided with a pair of light projection/reception systems having a light projection part and a light reception part provided side by side. Each light projection/reception system is arranged in a housing so that non-measurement surfaces face squarely. When viewing each light projection/reception system with the non-measurement surfaces caused to face squarely in a two-dimensional plane, a light projection part and a light reception part of one light projection/reception system, and a light projection part and a light reception part of other light projection/reception system are arranged in the housing so as to be in a point symmetrical position relation. Then, a ratio of a light projection range of each light projection part and a ratio of a light reception range of each light reception part are adjusted respectively so that an entire light projection range adding the light projection ranges of each light projection part corresponds to an entire light reception range adding the light reception ranges of each light reception part.SELECTED DRAWING: Figure 5
