Abstract
A holographic spectroscope for a two-motor reflection system for generating scanning patterns in which a light beam is first reflected by a first reflector connected to a first motor electrically connected to a first control circuit. A second reflector for reflecting the light beam reflected by the first reflector is connected to a second motor electrically connected to a second control circuit and to form scanning patterns. A holographic spectroscope for diffracting the scanning patterns is mounted in the optical path of the light beam from the second reflector. Therefore, the scanning patterns can be improved to be more variable.
