We present a system for multispectral image acquisition which is accessible via an Internet connection. The system includes an electronically tunable spectral filter and a monochrome digital camera, both controlled from a PC-type computer acting as a Web server. In contrast to the three fixed color channels of an ordinary WebCam, our system provides a virtually unlimited number of spectral channels. To allow for interactive use of this multispectral image acquisition system through the network, we developed a set of Java servlets which provide access to the system through HyperText Transfer Protocol (HTTP) requests. Since only the standard Common Gateway Interface (CGI) mechanisms for client-server communication are used, the system is accessible from any Web browser.
