Introduction

The Focus Premium Max, Focus Premium and Focus Core are high-speed three-dimensional laser scanners for detailed measurement and documentation. The scanners use laser technology to produce very detailed three-dimensional images of complex environments and geometries in minutes. The resulting images consist of millions of 3D measurement points.

Several models of the Focus scanner have been produced since its introduction. This manual covers the following models:

Focus Premium Max (400 m range)1
Focus Premium (200 m range)1
Focus Core (100 m range)1
Focus Premium (70 m, 150 m, or 350 m range)
Focus Core (70 m range).

The scanner is designed to scan objects at distances between 0.5 meters and up to 400 meters, depending on your model and license. Additional features, such as Flash, may require an extra license, depending on your scanner model. Contact your FARO Sales representative for information.

The scanner provides exceptional capturing efficiency, data quality and accuracy for professional applications across the construction, public safety, operations and maintenance and manufacturing markets.

Focus Premium Features

The Focus Premium Max, Focus Premium, and Focus Core provide superior area coverage per scan position with a range of up to 400 meters.
Intuitive control through the built-in touchscreen display and phone-enabled remote control capabilities by WLAN for seamless connectivity with FARO Stream app and FARO Sphere XG cloud-based collaboration platform.
On-site registration for faster project completion and real-time awareness of scan errors or missing data with the Stream app.
HYPERMODULATION^TM
High accuracy, high resolution, high speed laser scanning
Easy mobility, due to its compact size, lightness, and the integrated quick-charge battery.
High Dynamic Range (HDR) imaging method merges images captured with different exposure settings into one image with a greater dynamic range of luminosity.
Photo-realistic 3D color scans, due to the integrated color camera or panorama camera.
Integrated dual-axis compensator to automatically level the captured scan data.
Integrated GPS sensor to determine the scanner position.
Integrated compass and altimeter to give the scans orientation and height information.
Integrated high-speed SSD data storage for maximum scan capacity and lighting fast scan processing.
Rugged construction and housing that can withstand tough, day-to-day work.

The Focus scanners work by sending an infrared laser beam into the center of a rotating mirror . The mirror deflects the laser beam on a vertical rotation around the environment being scanned; scattered light from surrounding objects is then reflected back into the scanner.

Figure 2-2 Laser Deflection

For distance measuring, the Focus scanners use phase-shift technology. This means that constant waves of infrared light of varying length are projected outward from the scanner. Upon contact with an object, the light is reflected back to the scanner. The distance from the scanner to the object is accurately determined by measuring the phase shifts in the waves of the infrared light. HYPERMODULATION^TM greatly enhances the signal-to-noise ratio of the modulated signal with the help of a special modulation technology. The x, y, z coordinates of each point are then calculated by using angle encoders, which measure the mirror rotation and the horizontal rotation of the scanner. These angles are encoded simultaneously with the distance measurement. The scanner covers a 360° x 300° field of view.

Figure 2-3 Vertical and Horizontal Rotation

Additionally, the scanners determine the reflectivity of the captured surfaces by measuring the intensity of the received laser beam. Generally, bright surfaces reflect a greater portion of the emitted light than dark surfaces. This reflectivity is used to assign a corresponding value to each point.

The single point-measurements are repeated up to 2 million times per second. The result is a point cloud; a three-dimensional data set of the scanner's environment (hereafter referred to as the laser scan, or simply scan). Depending on the selected resolution (points acquired per rotation), each point cloud consists of millions of scan points.

The laser scans are recorded on a high speed SSD and can be exported via removable SD card, enabling easy and secure transfer to SCENE, FARO’s point cloud editing software, or on the FARO Sphere XG cloud solution.

This manual provides an introduction to the Focus Premium Max, Focus Premium and Focus Core. Read the safety information in chapter Safety Precautions and the step-by-step guide in chapter Getting Started before using the Focus scanner.

The scanner also has on-screen help that can be accessed during operation by tapping the Help button on the screen. For more information, see Online Help and Notifications.

A list of the potential fields of application of the Focus scanners can be found on the FARO website www.faro.com.

FARO Flash

FARO Flash is the fastest scanning method and can significantly reduce the time required for your scanning project when scanning. It's best for indoor environments with usual room sizes or outdoor environments with close objects. It is recommended for creating floor plans or to map general objects. FARO Flash may require an additional license dependent on your Focus model.

FARO Stream

Stream is a mobile app that connects FARO hardware with FARO Sphere XG cloud-based applications and services. By uniting hardware with cloud software, Stream makes on-site capture workflows more efficient and brings captured data directly into the FARO ecosystem. It does so by providing live feedback of the captured scans while performing its pre-registration function.

Stream provides the best on-site efficiency for data capture with the Focus Premium Max, Premium, and Core scanners for scan operations in architecture, engineering, construction and facility management. Users can be confident in the successful and complete scan data they collect in real-time, confident that no additional site visits will be required because of missing data and confident in radically expedited project finalization times as Stream and Sphere XG are already doing some of the work automatically while a scanner operator is returning from the field. Stream also provide the ability to include complementary data like field annotations and photographic images to the project after a scan is complete.

FARO Sphere XG

Sphere XG is a cloud application that provides you with a centralized, efficient, and collaborative environment across FARO point cloud applications and customer support tools for faster 3D data capture, processing, and delivery through a secure, single point sign-on process. With Stream, SCENE and Sphere XG, registration starts in the field and processing can be performed in the cloud while the scan operator is driving back to the office. This allows off-site colleagues to already work on the data or share it with end-customers.

Additionally, Sphere XG uses three customer service platforms: The FARO Knowledge Base, which provides technical product information, FARO Support, which provides 24-7 personalized service, and FARO Academy, which provides on-demand and live training and education programs.
