Patent ID: 7348542

Claim:
A system for detecting light, the system comprising: a compartment having a body defining an interior wherein the body has an interior surface and a length defined between a first end and a second end of the compartment; a cap having a bottom surface and walls wherein the walls are connected to the bottom surface wherein the cap is connected to the first end of the compartment; a platform attached to the walls of the cap wherein the platform is located at the first end of the compartment wherein the bottom surface of the cap, the walls of the cap and the platform define an interior of the cap wherein the interior of the compartment is adjacent to the interior of the cap wherein the platform is located between the interior of the compartment and the interior of the cap; a light source connected to the platform wherein the light source is located within the interior of the compartment wherein the light source emits light into the interior of the compartment wherein the interior surface of the compartment absorbs and diffuses an amount of the light emitted from the light source within the interior of the compartment; and a first detector located within the interior of the cap wherein the first detector detects an intensity of the light within the interior of the cap wherein the intensity of the light within the interior of the cap corresponds to an intensity of the light within the interior of the compartment which is not absorbed or diffused by the interior surface of the compartment and further wherein the intensity of the light with the interior of the compartment corresponds to the amount of the light not absorbed or diffused by the interior surface of the compartment wherein the cap and the compartment prevents diffraction of the light within the interior of the compartment and the interior of the cap.
