摘要： A range finder includes a laser transmitter, a laser receiver, a large-aperture objective lens unit, an image sensing device, a display device and a microphone. The laser transmitter is configured to emit a laser beam to a measured object. The laser receiver is configured to receive a reflected laser beam reflected by the measured object. The objective lens unit is configured to allow visible light reflected by the measured object to pass therethrough, includes an objective lens and a focusing lens and has a length defined by the objective lens and the focusing lens. The image sensing device is configured to receive the visible light passing through the objective lens and generate an image signal. The length is constant when the objective lens unit is moved with respect to the image sensing device for focusing operation.

摘要： A range finder includes a prism module and a prism adjusting mechanism. The prism module includes a fixing prism group and a movable prism group, wherein the fixing prism group is adjacent to the movable prism group. The prism adjusting mechanism includes a first adjusting group and a second adjusting group, wherein the first adjusting group includes a first adjusting member and a second adjusting member, and the second adjusting group includes a third adjusting member. The first adjusting member or the second adjusting member is rotated to axially move so that the movable prism group is rotated with respect to the fixing prism group about a first axis, the third adjusting member is rotated to axially move so that the movable prism group is rotated with respect to the fixing prism group about a second axis, and the first axis is perpendicular to the second axis.

摘要： A distance detector includes a main body, a laser emitting module, an image capturing module, an angle detecting mechanism, and a processing-control unit. The main body is configured to rotate about an axis. The laser emitting module is disposed on the main body and configured to emit a laser beam to a measured object, thereby forming a laser speckle thereon. The image capturing module is disposed on the main body and configured to capture an image of the measured object, which contains the laser speckle. The angle detecting mechanism is configured to detect an angular displacement of the main body from a starting position and generate angle data. The processing-control unit is configured to receive the image containing the laser speckle and the angle data to control rotation of the main body. A distance between the main body and the measured object is determined by using a triangulation method.

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.
