Abstract:
1. A light image sensor for testing opto-electronics for in-circuit test, the sensor comprising: an image sensor array configured to detect a light signal from a light source on a printed circuit assembly and generate an electrical analog signal in response to a detected light signal; a sampling stage configured to sample the electrical analog signal from the image sensor array; an analog-to-digital converter configured to digitize the electrical analog signal from the image sensor array into a digital signal for testing by an in-circuit test unit; an in-circuit test (ICT) unit coupled to the analog-to-digital converter and configured to match a color of the digital signal with a proven color value and to match an intensity of the digital signal with a proven intensity value; a lens coupled to the image sensor array and configured to receive the light signal from the light source; and a fiber optic link coupled to the lens and to the image sensor array and configured for transmitting the light signal from the lens to the image sensor array.
