Range Finder

摘要

A range finder includes a laser transmitter, an IR transmitter, a laser receiver, an objective lens, an image sensing device, a prism device, and a display device. At least one laser beam is emitted from a laser transmitter and reflected to a laser receiver by a measured object. An infrared ray is emitted from the IR transmitter and reflected to the image sensing device by the measured object. The prism device is disposed between the objective lens and the image sensing device, for guiding visible light and the infrared ray to the image sensing device and guiding the laser beam to the laser receiver. The display device displays the image of the measured object that is captured by the image sensing device.

主权项

1. A range finder, comprising:
a laser transmitter emitting at least one laser beam to a measured object; an infrared ray transmitter emitting an infrared ray to the measured object; a laser receiver receiving the laser beam that is reflected back from the measured object; an objective lens receiving visible light, the laser beam, and the infrared ray that are all reflected back from the measured object; an image sensing device receiving the infrared ray and the visible light that are captured by the objective lens and generating an image signal; a prism device disposed between the objective lens and the image sensing device and receiving the visible light, the infrared ray and the laser beam, wherein the visible light and the infrared ray are guided to the image sensing device in one direction, and the laser beam is guided to the laser receiver in another direction; and a display device displaying the image of the measured object that is captured by the image sensing device.
