Multispectral Image Capture Across the Web

Multispectral image acquisition typically results in a huge amount of data and often involves a complicated mechanical setup in which a given number of interference filters is mounted on a filter wheel in front of a monochrome digital camera. Such constraints present serious problems for multispectral image capture over a wide area network. We solved these problems by using an electronically tunable spectral filter and a modular client-server software architecture. The client parts of the software are implemented in Java and allow for interactive operation of the multispectral camera across the Web.
