Imaging
SPEA imaging test units are designed for the production functional test of proximity sensors, Time-of-Flight sensors, ranging sensors, UV and IR sensors.
The module integrates all the elements required for both the electrical and functional tests of the devices, including the equipment for the functional verification of the sensor working.
The sensor test is performed by measuring its feedback to a specific target placed at different, defined distances. Multiple proximity targets can be applied, changing distance, color, and light conditions (e.g. white light or IR illuminators).
A multi-station revolver unit allows the multi-stage operation on the test area: devices are tested on multiple stages in parallel, managing different test sequences on each stage. The first revolver station is dedicated to device loading/ unloading, while each of the others can house a different optical chamber box, with tester interface and contacting unit. Multiple targets can be placed on each stage, to functionally test the sensor working at different conditions of light intensity, color, distance. High-accuracy testing of UV sensors is based on AAA-class solar simulators.
Each test stage, each contacting unit, and each test module, is managed by a dedicated CPU, communicating with the test supervisor. This guarantees high operating speed, fast setup, and quick diagnostics. The test cell footprint is optimized by the high integration of modules and processes.
