Imaging technology has a rich history that began thousands of years ago. The reflection from a pool of still water or a shiny metal surface was arguably the first imaging method routinely used by mankind. With the advent of lenses, many other novel forms of optical imaging emerged, including telescopes and microscopes.

Using a lens, a pinhole camera, and a sensitized pewter plate, Ni?pce was the first person to permanently record an image. Optical photography and other forms of optical imaging have since become commonplace.

abstract on object detection using ultrasonic waves

The project is designed to demonstrate detection of any object ahead of the ultrasonic transducer. It can be used for applications like security area monitoring and wild life photography etc.This ultrasonic detector consists of two parts: an emitter, which produces a 40 kHz sound wave; and a detector, which detects this 40 kHz sound wave and sends the signal back to the microcontroller.The ultrasonic module is interfaced to the microcontroller of 8051 family. Whenever any object approaches ne ....etc
