OPT 3D Stabilization Technology and Intelligent Surface Auto-Adjustment Calibration Algorithm

To meet the precision inspection requirements for the smartphone Mid-Frames, OPT 3D stabilization technology and an intelligent surface auto-adjustment calibration algorithm achieve complete product coverage, enabling the integrated measurement of frame height, spacing, positioning, and surface defects in a single process through dynamic image capture.OPT's breakthrough solution combines 3D stabilization and an intelligent surface auto-adjustment calibration algorithm to create real-time precision point clouds. Its dual-height, gray-scale algorithm delivers ±0.01mm accuracy at triple the speed of 2D systems, excelling at detecting submicron defects on complex shapes while overcoming reflective surface challenges, providing reliable automated QC for 3C manufacturing.

OPT 3D Laser Profilers Product Series

Within the intelligent inspection solution utilizing OPT 3D stabilization and an intelligent surface auto-adjustment calibration algorithm, the OPT 3D Laser Profilers product series serves as the core component. Employing a 405nm semiconductor blue laser source combined with a high-transmittance optical diffusion system, it achieves diffraction-limited focusing across the target measurement area. This ensures near-theoretical minimum spot dispersion throughout the entire focal range, enabling precise capture of submicron-level surface deformation characteristics. Utilizing OPT's large-aperture, low-aberration light-receiving lens module enhances luminous flux capture efficiency. Combined with the OPT patented optical compensation structure design, it maintains consistent CMOS imaging magnification across the entire working distance range. This configuration improves sensor linearity accuracy, enabling precise detection of submicron surface features on products within a ±2μm measurement range.

The industrial-grade 3D high-speed CMOS sensor combines high dynamic range with lossless high-speed acquisition. Equipped with a high-performance FPGA and dedicated IC image processor, it achieves sub-pixel resolution reconstruction and ultra-precise linear processing. Through its innovative four-channel parallel architecture (sampling-reading-processing-output), the system accomplishes ultra-high-speed scanning at 67,000 profiles per second. This enables zero-miss online flying inspection with 100% defect detection capability, ensuring complete capture of all dimensional abnormalities.

The line laser 3D laser profilers operate on laser triangulation measurement principles. A semiconductor laser emitter projects a beam that is precisely diffused into parallel light through a cylindrical lens optical system, forming a laser line with strictly uniform spot size and spacing on the target surface, inducing either diffuse or specular reflection. The reflected light is then captured by a high-precision receiving lens module and accurately imaged on the CMOS sensor target surface. Based on the photoelectric response characteristics of each CMOS pixel, the system performs real-time conversion to determine corresponding height values and grayscale values.

Since its initial launch of 3D laser profilers in 2018, OPT has achieved comprehensive coverage across strategic industries, including new energy vehicles by 2022. In 2024, the company completed a major technological upgrade and officially launched its LPF2 series. The core technological advantages of the LPF2 series are primarily demonstrated in the following aspects:

1. Class 2M Laser Safety Rating: Excellent protection level

2. Enhanced Scanning Speed: 3000-18000 Hz adjustable range

3. Robust IP55 Enclosure: Compliant with IEC60529 standards

4. GigE Interface: Supports 100m maximum transmission distance

5. Standalone Operation: Eliminates external controller requirements for simplified integration 6. Factory Precision Calibration: Includes field installation calibration for enhanced measurement accuracy

7. Multi-Material Compatibility: Adapts to various surfaces/colors with FOV compression for ultra-high-speed scanning

8. Industry Standard Compliance: GigE Vision V2.0, GenICam, EMC/ROHS certified

OPT's 3D stabilization Technology and Intelligent Surface Correction Algorithm are specifically engineered for complex component inspection in the 3C industry, overcoming the limitations of traditional 2D detection. The system simultaneously captures critical dimensional parameters (including mobile phone frame height variations, assembly clearances, and positional tolerances) while detecting microscopic defects such as scratches and dents - all in a single scanning process.
