Laser rangefinders are devices that contain a laser to measure the distance from an item. Usually, such a gadget works by either the direct flight time method or the phase shift method. The two ways are described below. See the article on laser distance measurement for more distance measurement methods utilizing lasers.
Various gadgets were developed. Some can measure the distance from several kilometers, whereas others are built in a structure for far smaller spaces. The length obtained is often displayed on a digital display.
The main advantage of laser distance monitoring techniques is that laser light has a much smaller wavelength, allowing the transmission of a much more concentrated probe beam and thus achieving a higher transverse spatial resolution than ultrasonic or radio and microwave frequency (radar).

Laser range finders often have to view appliances so that the user can accurately direct the laser beam to the object of interest simply by controlling the device to the center of the image, which is designated by a crosshair so that the object of interest appears. (The distance measurement can be displayed on the same display device.) In other circumstances, a visible laser beam can be seen on a not too far object (from the measurement laser or possibly from a separate integrated Laser Pointer) for the targeted position check.
A laser rangefinder incorporates electronics, often incorporating a microprocessor, for operating the laser, calculating and showing the distance measured, monitoring and battery charging, etc., in addition to the laser, photodetector, and optical elements.

• It is a “window to the world”—you see with your eye as though through a window, rather than by any aerial picture or electronic screen.
• You can see beyond the margins of the frame lines and, therefore, beyond the image’s borders to help compose and anticipate. No blackout viewfinder during exposure.
• Coincidence rangefinder patches are sometimes simpler to concentrate on than other visual approaches.
• The frame lines are approximate, freeing you from the difficulty of accurate framing.
• The view isn’t “seductive,” which encourages you to deal with the matter more directly when you observe it with your eyes.
• The frame lines are imprecise; where the frame’s edges are, you’re never entirely sure.
• At least a slight parallax always exists.
• There is no method to preview field depth.
A rangefinder helps you to interact more closely with the world from a gestalt perspective. It highlights several of the technological issues involved in aiming and concentrating a camera. You could even claim that it’s a flawed system, but its poverty is not a bug.
