Draft:Single Pixel Camera

Single-pixel cameras represent a significant departure from traditional multi-pixel digital cameras. Here's how they work:

1. **Light Patterns**: They illuminate the subject with a series of spatially resolved patterns of light, similar to crossword puzzles⁵. 2. **Single Detector**: Instead of using millions of pixels to capture the image, a single-pixel camera uses just one detector to measure the intensity of light. 3. **Compressed Sensing**: This technique involves capturing fewer samples than traditional methods would require and then using algorithms to reconstruct the image¹. 4. **Lensless Design**: Single-pixel cameras do not require lenses, which can be advantageous in harsh environments or for wavelengths outside the visible spectrum¹. 5. **Efficiency**: Recent advancements have greatly reduced the number of exposures needed, making the process more efficient¹.

This technology is still evolving, but it offers exciting possibilities for the future of imaging.
