Primary imaging camera

Edwin land (1909 ~ 199 1) was an inventive genius in American photography in the 20th century. There are many inventions in his life, the most famous of which is his imaging photography. Interestingly, however, this invention that made him a giant in photography was due to his recreational photo-taking activities for his daughter.

19 12, Rand's daughter just turned 3. Rand likes to often take photos of his lovely daughter, but this clever little guy is always clamoring for his father to show her the photos he just took. The child's childish words touched his idea of invention: "Why can't we innovate and invent such a camera?" As a famous expert and inventor in the field of optical photography, Rand can take action quickly in this field with this idea. It only took him more than an hour to draft the theoretical concept of imaging system.

In fact, it is also interesting to say. His theoretical thinking is not purely original, but because he once invented the idea of imaging, and he recalled an earlier diffusion transfer washing method. This flushing method was first initiated by Idis Wade of Akfa Company, and Akfa applied it to the rapid copying system. However, Akfa can't see any connection between this method and the rapid imaging of the camera, and others can't see it, but Rand sees it deeply and holds on tightly.

1945, just after World War II, Rand went to England to show his research results to Ilford, who provided silver-containing emulsion for diffusion transfer washing to his company, hoping to get strong support and cooperation. The British, on the other hand, think that these demonstration technologies of RAND are interesting, but they have no future in practical use and are unwilling to cooperate with RAND.

After Rand returned to China, he had to rely on Kodak Company of Heasman in order to let his Polaroid Company master the production technology of photographic emulsion. However, Rand didn't want to rely on others, so he made a plan and decided to produce the emulsion himself. In the following few short years, how this project was completed and by whom caused some speculation, and caused a lawsuit between Polaroid and Kodak about the patent right of an imaging camera method. In the end, Polaroid won the victory and received $900 million in compensation.

1947, the world's first single-lens camera was born. This novel one-shot photography method became an instant hit and achieved great success almost overnight. This camera uses peelable film, and it can get Zhang Shen Brown's photo immediately after shooting. Because Rand is the designer of this brand-new camera, people regard this camera as a product invented by Rand.

1950, black and white primary imaging camera came out.

1963, the color primary imaging camera was successfully developed and put into the market. Since the early 1960s, Rand mainly served as the director of R&D, but rarely did basic research in person. The main research work of this special primary imaging film was done by others, especially a container invented by a truck driver. Fast and low transportation costs enable Americans to eat apples from New Zealand, use Japanese video recorders, put on jeans from Hong Kong and drink "Juarez" mineral water from France. Today, the imported goods we eat, wear and use are likely to arrive in containers.

The goods originally sent in boxes, boxes, bundles, bags, barrels and bags are now packed in sealed containers, with no description on them, only the product code, which is convenient for instrument testing and computer tracking. This tracking system is very accurate, and it can measure the position of the fleet that takes two weeks to reach within 15 minutes.

The above facts have contributed to another fundamental change in the world economy: the realization of the global "flow process". For example, a Japanese-made car tractor was shipped to a car factory in Kentucky in a sealed container and installed on an American car in less than an hour.

This mode of transportation has changed the face of world trade, and its significance is considered to be no less than the transformation of water transportation from sailboats to steamboats. Because the loading and unloading time of the dock has been reduced from a few days or even ten days to several hours, and it can hold several times the original goods, the time for transporting the same amount of goods from the United States to Europe has been shortened by four weeks. So, who initiated this revolution in transportation mode? It was invented by an American truck driver, who used his quick wits in transportation practice.

Marco McClane 19 13 was born in rural Maxwell, North Carolina. 193 1 year, he bought a van and ran it for six years. /kloc-one day in 0/937, when his car was parked at the pier in hoboken, New Jersey, he. While waiting anxiously for loading and unloading, I can't help thinking: can't we find a way to send the trailer directly to the ship, thus saving a lot of time and manpower?
