In a headlight tester, the main task of the electronics is measuring the position and intensity of the light beam.
Sinai Srl designed a system made of a cluster of photodiodes and a firmware capable of continuously calculating the position of the light beam.
Despite the cluster being composed of only ten photodiodes, the system can interpolate and calculate the position of the beam with high accuracy, even if the beam falls between two diodes.
The system also measures the intensity of the beam (in KLux) but this additional measurement it doesn't affect the calculation of the beam's position. |
The Headlight Tester system has many other features, among which:
-
Powering via battery
-
User interface with keyboard and alphanumeric display
-
Laser pointer
-
Printer for the measurement results
-
RS232 serial port
-
Wireless connectivity via Bluetooth or WiFi
-
Data transmission protocols compliant with the standards of european vehicle registrations
