What technique allows for the focus of bright objects using lasers?

The technique that allows for the focus of bright objects using lasers is laser focus. This method utilizes the properties of lasers, which produce highly collimated and coherent light beams. This means the light is emitted in a very focused manner, allowing for precise targeting and manipulation of bright objects.

When lasers are used for focusing on bright objects, they can produce a concentrated spot of light that enhances visibility and detail, enabling applications such as laser engraving, cutting, or medical procedures. The ability to finely adjust the focus of the laser beam means that operators can achieve a high level of precision and control, which is essential in many industrial and scientific applications.

In contrast, image scanning, video compression, and image compression deal with different aspects of visual technology and processing. These methods primarily focus on the capture, storage, and transmission of images rather than enhancing light focus or clarity through lasers. Therefore, they do not directly apply to the technique specified in the question.
