Controlled amount of heat is injected into a stacked die using a light beam, and the propagated heat is measuring with LIT camera from the other side of the die. The thermal image obtained can be characterized so that it can be used to calibrate the phase shift from a given stack layer, or can be used to identify defects in the stacked die. The process can be repeated for each die in the stack to generate a reference for future testing. The thermal image can be investigated to detect faults, such as voids in vias, e.g., TSV.

The imager includes a lens for focusing infrared light forming a thermal image onto a liquid crystal array thereby changing the temperature of the liquid crystals to alter a physical property of the liquid crystals. A source of visible polarized light is arranged to illuminate the liquid crystal array so that the polarization of light reflected from the liquid crystal array varies with changes in temperature of the liquid crystals. A cross polarizer receives and transmits therethrough the light reflected from the liquid crystal array, the cross polarizer adapted to change the intensity of the light. An imager receives and detects the change in intensity of the light from the cross polarizer so that the thermal image is recreated as an electronic signal. In a preferred embodiment, the physical property is index of refraction and the liquid crystal array includes birefringent nematic liquid crystals.

A mechanism of quantitative dual-spectrum IR imaging (QDS-IR) system for examining the breast cancer is reported. The major mechanism of the system is a pair of long-wave Infra-red (LIR) and middle-wave Infra-red (MIR) cameras with the keen temperature sensitivity and the high spatial resolution. The optical axes of cameras are calibrated by the help of two calibration makers set up on the seat for carrying an object to make them parallel to each other and locate on the same level. The design provides an imaging system with the high reproducibility supported by 7 free degrees and the high adjustability. The proposed system could ensure the positions of the object and two cameras are the same at the different time points and find the best relative positions between the seat and two cameras for the objects with different body types. Therefore, it has potential ability to detect breast cancer or monitor the effect of chemotherapy.

Clinical hand-held infrared thermometer with special optical configuration

Номер: US20130259087A1
Автор: Yonatan Gerlitz
Принадлежит: Individual

Method and apparatus for measuring temperature of a measured area of a surface without contacting the surface. The thermometer apparatus has an optical system which generates a correlative image of an infrared energy detector sensitive area at an image distance from the thermometer. A limiting aperture, having a size and a shape corresponding to those of the generated image, is between a mirror and the generated image. The measured area of the surface is between the generated image and the thermometer in use. With such a configuration, little infrared energy that does not originate from the measured area strikes the detector. Consequently, the energy reaching the detector is limited such that the size of the measured area remains constant, regardless of changes in the thermometer's field of view attributable to differences in the distance between the surface and the thermometer. A scan-and-integrate mode for practicing the invention is disclosed.
