An improved system and method for detecting leaks in substantially enclosed objects such as automobiles, airplanes, tanks, etc. uses an ultrasonic transmitter and an array of ultrasonic sensors positioned around the inner periphery of a cut out silhouette that corresponds to an outline of the objects under test. The silhouette is mounted in a frame that is designed to minimize ultrasonic reflections and preserve any amplitude information received by the ultrasonic sensors. As the objects are passed through the frame, ultrasonic amplitude readings obtained from the sensors are processed to determine if they are representative of a defective or leaking object. The position of the leak is determined by examining the amplitude of the individual sensor readings. The system is particularly well adapted for use in detecting defects in automobiles on an assembly line without interrupting the assembly process or damaging the car.

A neutral density (ND) filter made of an LWIR-transmissive, heat-resistant material is interposed between a longwave infrared (LWIR) imager and an entity that is highly emanative of both light and heat. According to exemplary inventive practice, the ND filter is a thermoplastic (e.g., polystyrene) sheet characterized by a thickness in the 1-2 mm range and a thermal conductivity≦0.13 W/m-K. Important parameters of the ND filter include LWIR transmittance (which depends on material and thickness) and thermal conductivity (which depends on material). The quality of the image taken of the entity is affected by the respective degrees of LWIR attenuation by, and heating up of, the ND filter. Accordingly, the material and the thickness of the ND filter are selected to optimize the image, in particular so as to avoid saturation and/or whiting-out of the image due to insufficient LWIR attenuation and/or excessive ND filter temperature.
