SEEPOS Measurement System

The SEEPOS Measurement System is a high-precision optical position measurement solution designed for real-time tracking of light and laser beam positions. Based on advanced Position Sensitive Detector (PSD) technology, SEEPOS integrates sensing, signal processing, and data output into a complete system, enabling accurate and continuous position monitoring in demanding environments.

In modern photonics and optical engineering, precise beam positioning is essential for system performance, alignment, and control. The SEEPOS Measurement System addresses this need by providing a robust, ready-to-integrate solution that simplifies implementation while delivering high accuracy and fast response. It is particularly suited for industrial automation, research instrumentation, and OEM applications where reliability and precision are critical.

What is SEEPOS Measurement System?

The SEEPOS Measurement System is an integrated optical measurement platform that uses PSD-based sensing to determine the position of a light spot with high precision. Unlike standalone detectors, SEEPOS combines the sensor, signal conditioning electronics, and processing capabilities into a unified system.

This allows users to obtain real-time position data without the need for complex external electronics or calibration setups. The system is designed to support both one-dimensional and two-dimensional position measurement, depending on the configuration, making it suitable for a wide range of photonic and industrial applications.

How SEEPOS Measurement System Technology Works

The SEEPOS Measurement System operates by combining optical detection with advanced signal processing:

• Optical detection: A PSD sensor captures the incident light or laser beam
• Photocurrent generation: The light generates charge carriers within the detector
• Signal distribution: Currents are distributed across electrodes based on beam position
• Signal conditioning: Integrated electronics amplify and normalise the signals
• Position calculation: The system calculates precise coordinates using signal ratios
• Data output: Processed position data is delivered via analogue or digital interfaces

This integrated approach enables:

• Continuous position tracking with high temporal resolution
• Reduced noise through optimised signal conditioning
• Simplified system integration compared to discrete detector setups

The result is a reliable and efficient measurement system suitable for dynamic and high-precision applications.
