Abstract
A system for modulating light is disclosed. The system comprises a detector (102) that receives input radiation (101) and generates detector data (104) representative of the input radiation (101). An information processor (106) receives the detector data (104) and generates control data (108). A filter (110) associated with the detector (102) receives the control data (108) and filters the radiation input into the detector (102) in response to the control data (108). A system for light modulation is disclosed. The system comprises a sensor (114) that receives input radiation (101) and generates detector data (104) representative of the input radiation (101). An information processor (106) receives and processes the detector data (104) and generates control data (108). A filter (110) receives the control data (108) and filters the radiation in response to the control data (108). A method for modulating light is disclosed. Step one calls for detecting input radiation (101) with a detector (102) to obtain detector data (104). Step two requires processing the detector data (104) to generate control data (108). Step three provides for transmitting control data (108) to a filter (110). T…
