Technology is gaining its height. Every day we come across something new which is far away from the reach of our imagination. Now also same thing happens researchers have modernized the old version camera through which you can capture high defined 3D images even from 1 kilometer away.
If we talk about general camera then it is restricted to capturing only 2D images and we could not able to get clear images from far distance. To measure distance from far object the concept that researchers have used is to bounce back the laser beam from the object and then measure the time taken by the light to travel back to a detector.
According to Gerald Buller, professor at Heriot-Watt University in Edinburgh, Scotland, says that though it is very difficult to take a picture of an object which is far away from us and do not reflect back laser beam but researchers have tackled this problem very cleanly and has developed a brilliant device which makes such difficult task possible.
A new system is developed in which a low power infrared laser beam rapidly strikes the object and records parameters like pixel by pixel, round trip time. The approach used is to give low power route to depth imaging of small targets which provides better striking capability. This camera also scans static, human made targets with some alteration in the image processing software.
