PHD

Like the standard WHD, the PHD (pinhole detector) has a wider field of view then other detectors and is capable of capturing single events (flashes of radiation) as short as 100us. It can detect very small holes and defects in any product in its field of view. Flash of light generated by pinholes passing over its infrared bar are sensed by the detector, converted to electrical signals, and amplified.

A custom Windows application was developed to configure and monitor the sensor's operation.

The standard sensor contains 4 detectors modules, each covering a 25 degree field of view (FOV).
