Method and system for imaging an object or pattern

A system for imaging an object comprising:

• a light source positioned to transmit light along a first path for illuminating at least a portion of the object;
• a first photo sensitive device positioned to detect light reflected from the object at a first preselected position and generating a first signal representing information concerning the light detected;
• a photodetector array having a plurality of photodetectors positioned to detect light reflected from the object at a second preselected wherein said photodetector array generates a plurality of second signals representing information concerning the light detected;
• a photodetector, in communication with the photodetector array, that receives the plurality of second signals and generates a third signal as a function of the plurality of second signals;
• and
• a processor in communication with the first photo sensitive device and the summing amplifier that receives the first signal and generates a first image of the at least a portion of the object as a function of the first signal, and that receives the third signal and generates a second image of the at least a portion of the object as a function of the third signal.

A system for imaging a semiconductor package comprising:

• a light source positioned to transmit light along a first path for illuminating at least a portion of the semiconductor package;
• a first photo sensitive device positioned to detect light reflected from the semiconductor package at a first preselected position and generating a first signal representing information concerning the light detected;
• a photodetector array having a plurality of photodetectors positioned to detect light reflected from the semiconductor package at a second preselected wherein said photodetector array generates a plurality of second signals representing information concerning the light detected;
• a photodetector, in communication with the photodetector array, that receives the plurality of second signals and generates a third signal as a function of the plurality of second signals;
• and
• a processor in communication with the first photo sensitive device and the summing amplifier that receives the first signal and generates a first image of the at least a portion of the semiconductor package as a function of the first signal, and that receives the third signal and generates a second image of the at least a portion of the semiconductor package as a function of the third signal.
