Development of Infrared Image Sensor Capable of Contact-less Temperature Measurement of an Object
OKI Semiconductor and Nissan Motor Corporation have jointly developed a medium-resolution (approximately 2,000 pixels) infrared image sensor capable of measuring temperature of objects in a non-contact fashion while providing an easy way to obtain thermal images. The newly developed ML6540WD infrared image sensor receives infrared rays from an object at 48 x 47 (2,256) pixels resolution, and then converting them into voltage via thermopile, and selects pixels is made with a clock signal output from client host CPU, allowing thermal images to be easily obtained by capturing an amplified signal with host ADC while performing additional signal processing. Its built-in op-amp circuit amplifies the infinitesimal voltage of the thermopile for conventional output signal level. Read more
