As such its design inputs were derived from our interactions with our project advisors, Dr. Roy S. Berns, Prof. Jennifer Kruschwitz, and Samuel Steven.  \nTeam Member Responsibilities  \n\n| Team Member | Responsibility |\n| --- | --- |\n| Joseph DiFabio | ● Scribe\u003Cbr>● Optical Design |\n| Maggie Han | ● Project Coordinator\u003Cbr>● CAD-Mechanical |\n| Angel Morales | ● Customer Liaison\u003Cbr>● Testing & Modeling |\n| Marissa Traina | ● Document Handling\u003Cbr>● Colorimetry |\n\nVision  \nThis product is envisioned as a tripod-mountable camera working with an attached Liquid Crystal Tunable Filter (LCTF) and lens system in order to obtain high-quality, monochromatic images, primarily of painted artwork. A series of these images will be obtained by adjusting the wavelength filter on the LCTF. Having these images will enable us to create a vector in color-space that can be used to capture the true color of various artworks, allowing for improved archival and reprinting abilities. This product is also aiming to be low-cost, and as a result, will seek to utilize already-existing camera models, lens attachments, and LCTFs so that this system can be easily reproducible.  \nEnvironment  \nThe system will be designed for use in a lab or studio type environment. The device should be designed for use at approximately 40-100 degrees F, and so that condensing does not occur at any level of humidity on this temperature range. Since this product should be constructed with commercially available components, these standards will be met according to the specifications of these components.  \nThe lighting the customer intends to use with this device is established as common flash bulbs used in photography-customer states that lighting design is beyond the scope of the project.  \nRegulations and Risk Factors  \nDue to the primary focus of utilizing commercially available technology (to reduce costs), the resulting product will adhere to the laws and regulations of the components. No alterations will be made which risk the safety of the user or which violate OSHA regulations.  \nProduct Requirement Document  \nThe following details describe the requirements for the end product.  \nFirst and foremost, the resulting imaging system should aim to be composed of already-available camera models (ideally, the Canon EOS 5D Mark III, as it is the one Dr. Berns currently uses), lens attachments, and Liquid Cr","cbCait7tNfgV7ZhR","https://ap.wps.com/l/cbCait7tNfgV7ZhR","pdf",249372,"English","# Revision History\n## Statement of Advisors\n## Team Member Responsibilities\n## Vision\n## Environment\n## Regulations and Risk Factors\n## Product Requirement Document\n## Options for Customer\n## Timeline\n## Reference","[{\"question\":\"What imaging purpose does the multi-spectral system serve?\",\"answer\":\"It is designed to capture high-quality, monochromatic images of painted artwork by tuning the LCTF wavelength.
