【Abstract】 The three dimensional microstructure LAPS array chip based on the MEMS technology was introduced in detail. The surface of LAPS chip was of 5×7 sensitive elements, and on each of them were the silicon tips of 40×40 array, the array of optical coupling windows were setup on corresponding backside of the chip. An 5×7 IR LED matrix is used as the light source, which is directed to optical coupling windows on the backside of the chip. This paper presented SEM photo of LAPS array chip and testing results of a variety of biochemical parameter, and discussed the thickness of the chip and the effect of the LAPS curve linearity on the performance of the LAPS system.更多还原
