Difference between photoelectric devices and traditional thin films

The difference between photoelectric devices and traditional thin films lies in their different principles and processing methods.

1, the principle is different: photoelectric device is a device that converts optical signals into electrical signals by photoelectric effect, and it is an electronic imaging technology; Traditional film is an optical imaging technology, which is an image recorded with photosensitive materials based on optical principles.

2. Different processing methods: The signals imaged by photoelectric devices can be directly digitally processed and stored by computers, while traditional films need to be developed, fixed and other chemical treatments to get stereoscopic images.
