Ultra sonic Scanner

I had the idea to create an ultra sonic scanner, but i did not know exactly how it will be built. I began with a support for a servo on freecad. the first assembly, i realise quickly that it will not work properly. I understood that i have to change the shape... I then test the movement of Ultrasonic detector with an Arduino Uno. The final goal is to show an image of 120° X 23° on a LCD color 1.8" ST7755 with the help of an Arduino Nano. I had to find how to make the movement of scan, i do it like old TV with cathodic tube line by line top to bottom. I made the first scan and produce an image on the screen. I had to think a 3.8 Vdc power supply for servo. It was a bit messy, but the project was progressing. The Arduino Nano board was already made, and i just add the 3.8 Vdc power supply on it. I then add wires for ST7735 and all others cables for Ultrasonic detector and the two servo.Meaning of what we see on an image, dark green is an object near detector (black zone is me and the camera) , light green is a long distance far from detector, and red parts are ultrasonic sound that have been Transmitted but no echo was received.
