Laser rader can achieve high precision and high frequency distance measurement through related ranging principles and optical algorithm, so it is widely used in automatic driving, robot autonomous navigation, map mapping, resource surveying, etc. Compared with conventional radar, laser rader has low power dissipation, small size, high resolution and strong anti-interference ability, but it is still inevitably easily affected by ambient temperature, resulting in reduced measurement accuracy. In order to improve this situation and improve the efficiency of laser rader, NTC thermistor chip will be placed in it as temperature measurement component.
In order to prevent the occurrence of thermal runaway caused by long-term high-temperature operation of laser rader, it is necessary to use NTC thermistor chip as an auxiliary to better balance the operating temperature of laser rader. Using the characteristics of high-precision temperature control of NTC thermistor chip, laser rader can effectively improve its own performance and ensure that it can be accurately detected when working near the temperature critical point.
Gold electrode NTC thermistor chip developed and produced by EXSENSE Electronics Technology Co., Ltd. is suitable for the bonding process, which can meet the high-density surface mount of laser rader; It is high accuracy (can up to ±0.5%), which can meet the high- accuracy measurement requirements of laser rader; It is high stability, which can assist laser rader to work smoothly in high temperature, high humidity and other harsh environments. As the electrode layer of NTC thermistor chip, the gold electrode has better consistency, effectively preventing the increase of self-heating caused by high power dissipation of laser rader, and avoiding jitter, distortion,etc. of the laser beam.
