Laser Alignment Verification Module

The Laser Alignment Verification Module is a critical subsystem within the Integrated Radiotherapy Linear Accelerator Assembly System that ensures accurate spatial positioning of therapeutic radiation beams. It continuously monitors and validates the alignment of patient positioning lasers against the linear accelerator's isocenter, providing real-time feedback to maintain sub-millimeter accuracy required for precise tumor targeting while minimizing radiation exposure to healthy tissues. The module employs high-resolution optical sensors and photodetectors to measure the position of alignment laser beams. It compares the detected beam positions against calibrated reference points, processes the data through embedded microcontrollers, and generates correction signals when deviations exceed tolerance thresholds. The system typically uses interferometric or triangulation-based measurement techniques to achieve micron-level precision. Key specifications include a measurement range of 0–100 mm, accuracy of ±0.05 mm, and resolution of 0.01 mm. It operates within a temperature range of 10–40 °C and can be stored at -20–60 °C. The module is rated IP54 for ingress protection and operates on a 24 V DC supply with power consumption of ≤5 W. It communicates via RS-485 and uses a visible red laser with a wavelength of 635 ±5 nm, classified as Class 2 per IEC 60825-1. The unit weighs ≤1.5 kg and has dimensions of 120×80×60 mm. Materials include optical-grade glass, aluminum alloy housing, silicon photodetectors, and printed circuit boards.
