Abstract: The application provides a multi-mode handheld optical device. A visible light assembly includes at least one visible light imaging module, which includes, arranged in sequence, an objective lens group and a beamsplitter. When a laser ranging mode is turned on, a laser reflected back by a detection target is received by the objective lens group and travels along the corresponding visible light path, and is subjected to separation by the beamsplitter to deviate from the corresponding visible light path for use in calculation of distance information of the detection target to be displayed on a display module. When an infrared mode is turned on, the infrared assembly collects an infrared light of the target field of view for conversion into an infrared image to be displayed on the display module. The distance information and/or the infrared image displayed on the display module finally fuse with the visible light image.
