Deciphering the Enigma of Laser Autofocus Technology
Exploring the Realm of Laser Autofocus
Laser Autofocus Technology in Mobile Cameras involves equipping a laser transmitter/receiver system that gathers distance data between the phone and the focal object. Positioned on the rear left side of the camera module, this transmitter emits a low-power laser beam, forming pulses. Upon encountering an obstacle, the reflected beams are detected by the laser sensor.

Advantages of Laser Autofocus in Photography
- The rapid speed of the laser enables almost instantaneous and precise distance measurement, unaffected by environmental conditions such as temperature, humidity, and light.
- Remarkably fast autofocus speed, approximately 0.276 seconds.
Principles Behind Laser Autofocus Technology
The laser autofocus mechanism differs significantly from other conventional autofocus types. The Laser AF module at the rear emits infrared light and a low-intensity laser beam through dedicated lenses.
Principles Behind Laser Autofocus Technology
On the outer side of the elliptical-shaped infrared sensor to the left of the camera, its role is to deflect the emitted infrared rays and then retrieve information about the reflected images.
A low-intensity laser beam passes through dedicated lenses in a straight line.
Subsequently, electronics measure the number of cyclical movements for each infrared wave, gradually forming the accurate near and far range of the object. After the image processing unit receives precise distance measurements from the device to the object or scenes requiring focus in front of the lens, it locks the corresponding focal length. All of this happens in real-time without encountering any obstacles.
