Optical In-Display Fingerprint Sensor Tester
SG-MPX is designed and made for testing optical fingerprint sensor. The uniform optical beam can cover the full smartphone screen. The output light intensity can be achieved to 300 lux for Green light and > 8000 lux for white light. SG-MPX can not only be used to be an environmental light simulator for developing fingerprint recognition algorithm in ISP chip, but also can be upgraded to test and analyze the sensor properties, such as Quantum efficiency, Spectral Response, System Gain, Sensitivity, Dynamic Range, Dark Current/Noise, SNR, Saturation Capacity, Linearity Error (LE), DCNU (Dark Current Non-Uniformity), PRNU (Photo Response Non-Uniformity.

Overview

Optical In-Display Fingerprint Sensor Tester

SG-MPX is designed and made for testing optical fingerprint sensor. The uniform optical beam can cover the full smartphone screen. The output light intensity can be achieved to 300 lux for Green light and > 8000 lux for white light. SG-MPX can not only be used to be an environmental light simulator for developing fingerprint recognition algorithm in ISP chip, but also can be upgraded to test and analyze the sensor properties, such as Quantum efficiency, Spectral Response, System Gain, Sensitivity, Dynamic Range, Dark Current/Noise, SNR, Saturation Capacity, Linearity Error (LE), DCNU (Dark Current Non-Uniformity), PRNU (Photo Response Non-Uniformity.

Key Features

  • Large Uniform Optical Beam size which can fully cover the full smartphone display.
  • The monochromatic light output intensity can ≥ 250 lux.
  • The max white light intensity output can ≥ 8,000 lux.
  • The light intensity can be computer-controlled and provide 4-order intensity adjustment.
  • Customized test fixtures according to user’s device under test.
