摘要： Disclosed are a dual-optical-path spectrophotometer and a color measurement method thereof. The spectrophotometer includes an integrating sphere, a light source, and a sensor. A second shutter, a semi-reflecting and semi-transmitting device and lenses are arranged between the detection hole and the sensor, and a light guide device and a first shutter are arranged between a light guide hole formed in the integrating sphere and the semi-reflecting and semi-transmitting device. The color measurement method includes the following steps. A first shutter is closed, a second shutter is opened, light, reflected by the measuring opening, enters a sensor and the sensor measures a spectral reflected signal of the object surface. The first shutter is opened, the second shutter is closed, reflected light enters the sensor, and the sensor measures a spectral reflected signal of a light source. A final sampled signal is calculated.
