Upconversion multichannel infrared spectrometer.
A multichannel IR spectrometer using a standard silicon CCD array is demonstrated. Sum frequency generation between an ultrafast optical pulse and a frequency-dispersed IR beam generates a spatially extended optical signal that is collected on a generic CCD video camera. This method provides an inexpensive and efficient alternative to conventional multichannel IR arrays.
