DETAILED DESCRIPTION OF THE DRAWINGS

[0017] The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

[0018] FIG. 1 shows an exemplary emulation system 1 having an emulation container 3. Container 3 has two apertures 5 on opposing sides of the container. An EMR beam 7 can be propagated through the container by entering a first aperture and exiting a second aperture. EMR power, beam quality, beam profile, etc. can be measured, and the resulting data can be utilized to test models and create new models. Because longer optical paths provide better analysis of EMR beams, each container 3 is generally longer (e.g., from aperture to aperture) than wide or tall.

[0019] FIG. 2 shows a block diagram of the components of an exemplary emulation system. A plurality of peripheral systems can be coupled to the walls of container 3 to enable a variety of functions or precision control. Peripheral systems can include a vacuum pump 23, humidity control mechanisms (e.g., humidifier 29), temperature control mechanisms (e.g., a heating element 21 and cooling element 25), and at least one fan 27.

[0020] FIGS. 3A-B show additional views of an exemplary container 3 with a heating element 21 (e.g., a wire with an electrical current 35 passing through the wire). The wind speed, temperature, pressure, and humidity can be measured by well-known measurement devices (e.g., hygrometers, sonic anemometer, etc.) traceable to known measurement standards. In exemplary embodiments, a controller can be configured to activate container peripherals until particular readings are recorded by sensors 31 (e.g., activate a heating element until a particular temperature is reached). It is generally preferable to put the heating element in the bottom of the container 3 (and likewise cooling elements in the top of the container) for better temperature regulation.

[0021] FIG. 4 shows a top section of an exemplary container with a humidifier 29 installed within top wall 41. It is generally preferable to put the humidifier 29 in the top section to facilitate dispersal of water vapor throughout the container. A seal 43 prevents the humidifier 29 from interacting with the internal air when EM beam is operating or when humidity levels have been satisfactorily achieved.

[0022] FIG. 5 shows an isometric view of an exemplary container 3. The bottom interior surface of container 3 is a heating element 21 (e.g., a hot plate) and the top interior surface of container 3 is a cooling element 25 (e.g., a cold plate). Side walls 53 are insulated so that the temperature within container 3 can be more precisely controlled, and the system can be used in a variety of laboratory settings.

[0023] FIGS. 6A-C shows exterior views of an exemplary container 3. FIG. 6A shows a front/back view of a container 3 with aperture 5. FIG. 6B shows an input/out panel 63 and control panel 61 placed on the exterior surface of a container side. FIG. 6C shows a top down view of a container with the top side removed. Fan arrays 65 can be configured to blow air into the container on a first side and out of the container on a second opposing side. It is generally preferable to put the fan arrays 65 on the side walls of container 3 to better emulate wind effects.

[0024] FIGS. 7A-C show a cross sectional side views of an exemplary container 3. Humidifier 29 and cooling element 25 are placed in the top section of the container so that the water vapor and cooled air will sink. Vacuum pumps 23 are placed in the bottom section of the container to remove air/water vapor from the container. Interior wall 67 can have embedded sensors 31 (e.g., to measure temperature, pressure, water content, etc.).

[0025] FIG. 8 shows exemplary emulation systems with connected containers 3 in linear and/or stacked configurations. Containers 3 can vary in size such that additional or fewer peripherals can be installed on a single container 3, or containers 3 can be coupled together to provide additional peripherals. When coupled, adjoining walls of containers 3 can be removed such that a single cavity is formed within containers 3. When the containers are linearly coupled, all of the apertures are aligned such that an EMR beam can pass through all of the coupled containers. Container 3 walls can be retractable shutters for automated opening and closing. Each container 3 can be configured to automatically retract the shutter walls when desired atmospheric conditions are met within each container 3.
