Nice to play with such creation, but conceptually wrong and unusable in detecting things of value. |
Esteban's method has nothing to do with spy cameras. He used a modulated laser in the infared spectrum to transmit. And then detcted the bouncing back lower frequency modulating frequency. Discrimination is possible, but depth is very low due to the use of the IR laser for transmission. This is why i suggested using a MASER of a slightly lower frequency for transmission and then you may get depth and discrimination.
Please understand your technologies before posting quotes of "he is wrong" as you become and sound like a
fool in front of everyone.
