Abstract:
1. A method for synchronously driving light-dispersing elements for driving a first light-dispersing element and a second light-receiving element in a light-dispersing including: a first light-dispersing unit having the first light-dispersing element and a first pulse motor for driving the first light-dispersing element; a second light-dispersing unit having the second light-dispersing element and a second pulse motor for driving the second light-dispersing element; and a pulse transmitter for transmitting a first pulse number of pulses to the first pulse motor and a second pulse number of pulses to the second pulse motor, wherein the first pulse number of pulses is necessary for sequentially changing, at predetermined intervals, a wavelength of monochromatic light produced by the first light-dispersing device, and wherein the second pulse number of pulses is necessary for sequentially changing, at predetermined intervals, a wavelength of monochromatic light produced by the second light-dispersing device, and the method comprising the steps of: determining a transmission rate of the first pulse number of pulses based on a pulse rate within a start region, a stop region, or a slew range of the first pulse motor; calculating a first pulse transmission time from the first pulse number of pulses and the transmission rate of the first pulse number of pulses; and transmitting the second pulse number of pulses to the second pulse motor within the first pulse transmission time.
