PCT No. PCT/IL96/00192 Sec. 371 Date Jun. 25, 1998 Sec. 102(e) Date Jun. 25, 1998 PCT Filed Dec. 25, 1996 PCT Pub. No. WO97/26514 PCT Pub. Date Jul. 24, 1997A device for simultaneously determining the direction and wavelength of an incident light beam. The device includes a transparent block and a diffraction grating for diffracting the incident light beam to produce a number of diffracted beams within the transparent block. The device further includes a detector array generating an output indicative of positions of intersection of the diffracted beams. Finally, the device includes a processor for processing the output to determine the direction and wavelength of the incident light beam. |
