He "changed careers" many times to meet national needs and built my country's first photolithography machine!

Under the cultivation and education of the Party, I have mastered certain scientific and technological knowledge in my business and can use my knowledge to serve the people. Looking back on my growth process, both the progress in thought and the growth in profession are entirely the result of the Party's cultivation.

——Excerpt from Jiang Wenhan’s “Application for Party Membership” in December 1982

Jiang Wenhan's hand-filled page of "Party Membership Application"

The stars can be seen from afar

Strong triggering of nuclear fusion

A deep glimpse into the unknown secrets of visual cells

He pioneered the field of adaptive optics

Helping my country's cutting-edge scientific research to be at the forefront of the world

The first proximity/contact lithography machine in China

The first ballistic camera was created by him.

He is the pioneer of adaptive optics in my country

Optoelectronics Engineering Expert

Jiang Wenhan, Academician of the Chinese Academy of Engineering

Jiang Wenhan

Born in the war years of foreign invasion

He experienced human suffering

Determined to serve the country through scientific research

Graduated from university at the age of 22

He devoted himself to the fiery revolutionary construction

Participated in the research of the first large-scale movie theodolite in New China

Successfully verified the idea of ​​using friction transmission for large theodolites

Solved the problem that micron-level thrust bearings could not be measured at that time

Jiang Wenhan's work photos

1971

Jiang Wenhan was ordered to enter Shu

In the deep mountains and dense forests

Participated in the construction of the Institute of Optoelectronics Technology of the Chinese Academy of Sciences in two years

1975

China's first ballistic camera was born here

Four years later

China's first proximity/contact lithography machine was launched here

Jiang Wenhan is looking up information

The 1978 National Science Conference was successfully held

China ushered in the spring of science

Jiang Wenhan, who once worked in many fields and had a broad vision

Focusing on a "less popular" subject

Adaptive optics

This is a comprehensive

New technologies in various disciplines such as optics, mechanics, electronics, computing, and materials

There are only a handful of reports internationally.

Jiang Wenhan's work photos

Jiang Wenhan is determined to sit on the "bench"

He led a team of four people to transform the silkworm-raising bungalow into a laboratory

Building an optical test platform on a thick steel plate

Started the scientific research journey of China's first adaptive optics laboratory

then

This is a very lonely road.

Jiang Wenhan's work photos

1986

Adaptive optics systems are used in

Wavefront Error Correction of Laser Fusion System

The final focal spot energy concentration is increased by 3 times

Internationally hailed as "the first Chinese method used in a Chinese device"

1990

Adaptive optics systems are used in

Yunnan Observatory 1.2m Telescope

Achieved adaptive optical correction for astronomical targets

The telescope's resolution has been improved by nearly an order of magnitude

Jiang Wenhan's work photos

1997

Adaptive optics systems are used in

Correcting high-order aberrations of the human eye and acquiring high-resolution images of the retina

The size of the device is only one-tenth of similar products in the United States

The world's first miniaturized high-resolution imaging device for the human eye

Jiang Wenhan

Entering the new millennium

Adaptive optics applications are flourishing

Leading the world

Changing careers several times to meet the needs of the country

Seeking truth and being pragmatic, fearless of crossing boundaries

Jiang Wenhan

Joined the Communist Party of China in December 1982
