Optical splash communication in downhole applications

A first downhole tool, comprising

• a first electrical element;
• a second electrical element, wherein the first electrical element and the second electrical element are positioned within a first inner space;
• and
• an optical splash signal, wherein the optical splash signal is transmitted from a light source of the first electrical element into the first inner space to a detector of the second electrical element via free space, wherein
• the first downhole tool is coupled to a second downhole tool;
• the second downhole tool comprising a third electrical element positioned within a second inner space of the second downhole tool;
• and
• at least one opening is provided between the first downhole tool and the second downhole tool to facilitate transmission of the optical splash signal from at least one of the first electrical element or the second electrical element to the third electrical element of the second downhole tool.

A method for communicating downhole data between elements of a downhole tool, comprising:

• deploying a first downhole tool downhole, wherein the first downhole tool comprises a first electrical element and a second electrical element;
• maintaining bidirectional communication between the first electrical element and the second electrical element via an optical splash signal;
• encoding digital downhole data from one or more receivers of the downhole tool in the optical splash signal;
• transmitting the optical splash signal, from a light source of the first electrical element to a detector of the second electrical element, via free space into a first inner space, wherein the first electrical element and the second electrical element are disposed within the first inner space;
• transmitting the encoded digital downhole data via the optical splash signal to an information handling system;
• and
• adjusting one or more drilling parameters based, at least in part, on the encoded digital downhole data transmitted via the optical splash signal, wherein
• the first downhole tool is coupled to a second downhole tool within the borehole;
• the second downhole tool comprising a third electrical element positioned within a second inner space of the second downhole tool;
• and
• at least one opening is provided between the first downhole tool and the second downhole tool to facilitate transmission of the optical splash signal from at least one of the first electrical element or the second electrical element to the third electrical element of the second downhole tool.
