SOH President Dennis Hirota never forgot his early Air Force training at the advanced weapons lab in New Mexico, where practical applications for breakthrough technologies were developed. Dr. Hirota continues that mission today, continuing to encourage the use of technology to solve real-world engineering and surveying challenges. 

Sam O. Hirota, Inc. specializes in providing cutting-edge laser scanning services that empower  clients to unlock a world of possibilities. With our state-of-the-art technology and expertise, we harness the power of laser scanning to deliver value to our clients.

What exactly is laser scanning, and how can it benefit you?

  • Laser scanning is a highly precise and accurate technology that captures detailed 3D data of objects, structures, and environments. Our advanced laser scanners emit a laser beam that rapidly measures thousands of points per second, creating a dense and accurate point cloud representation. This representation allows for precise measurements, analysis, and modeling, ensuring that every aspect of your project is captured accurately

  • Time and Cost Efficiency: By leveraging laser scanning technology, we help our clients save time and costs throughout their projects. Traditional surveying and measurement methods often require extensive manual labor and multiple site visits. Laser scanning eliminates the need for these repetitive tasks by capturing comprehensive data in a series of scans. This efficiency translates into faster project completion, reduced labor costs, and minimized disruptions to ongoing operations.

  • Enhanced Visualization and Design: Laser scanning generates highly detailed 3D models and point clouds that provide an immersive and realistic visualization of the scanned object or environment. These visual representations enable our clients to gain an understanding of their project they might not otherwise have, and to make informed decisions. Additionally, the accurate measurements obtained through laser scanning aid architects, engineers, and designers in creating designs and reducing design conflicts.

  • Retrofitting and As-Built Documentation: Laser scanning is particularly valuable in retrofitting and documenting existing structures. By scanning an existing building or infrastructure, we create a digital twin that serves as an accurate representation of the current conditions. This digital twin can be used for renovation, retrofitting, and repurposing, eliminating the need for time-consuming manual measurements.

  • Improved Safety: Safety is paramount in any project, and laser scanning plays a crucial role in ensuring a safe working environment. By capturing detailed 3D data, laser scanning helps identify potential hazards, clashes, or inconsistencies in a design. This proactive approach enables early detection of issues, reducing the risk of accidents, and improving overall safety on construction sites or in industrial environments.

Terrestrial laser scanning involves moving a scanner to different areas of an indoor or outdoor space to capture as much information as possible.

Advantage: Accuracy


Mobile mapping systems allow fast and accurate capture of large indoor and outdoor spaces.

Advantage: Mobility, speed, flexibility


Handheld scanning and photogrammetry can capture details of historic building elements as no other device can.

Advantage: Close-range detail, mobility, speed
