Heilongjiang Hagongda detector laser radar can replace high-priced foreign products

[China Instrument Network Instrument Development] With the development of artificial intelligence, the rise of automatic driving and assisted driving has promoted the application of laser radar. Recently, Heilongjiang Province, Harbin Dahuasheng Electronics Co., Ltd. developed a variety of avalanche photodetectors, including silicon-based near-infrared micro-pixel avalanche photon counters for the first domestic.

As an important core device in the optoelectronics industry, the detectors have a wide range of applications and even include emerging communication technologies. Linear APD detectors are widely used in the field of surface topography, atmospheric exploration, space technology, three-dimensional virtual reality, robot vision and other fields.

The team of avalanche single photon detectors of HIT Huasheng Electronic Co., Ltd. relied on the research basis of HIT to independently develop various avalanche photodetectors, among which the silicon-based NIR micro-pixel avalanche photon counter was the first in China.

It is understood that this result is optimized through the combination of CMOS and BIPLOAR bipolar semiconductor process innovations using semiconductor manufacturing processes. It is easy to mass produce, easy to CMOS compatible, and can replace high-priced foreign products.
