Title:
LASER DISTANCE MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2018028484
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve light collection efficiency in a short distance range.SOLUTION: An embodiment of a laser distance measurement device comprises an emission unit, condenser lens, and measurement unit. The emission unit emits output light generated by a light source. The condenser lens focuses reflection light, or the output light emitted from the emission unit and reflected by an object, on the detection unit. The measurement unit measures distance to the object based on the reflection light detected by the detection unit. The emission unit is disposed in a light path of the output light in a condenser lens plane and is supported by the condenser lens.SELECTED DRAWING: Figure 1A
