摘要： A probe-type online biomass detection apparatus capable of being subjected to high-temperature sterilization includes an optical fiber probe (1), a light source and light receiving sensor module (2), and a signal processing module (3). A portion, which is required to touch cytosol, of the apparatus adopts a detachable design scheme, to meet requirements for high-temperature sterilization of the probe (1). In the meantime, with regard to influence of bubbles in a fermentation tank on measurement values, a bubble filtering structure is provided, to reduce flow rate and number of the bubbles in the measurement area; and a measurement signal is filtered and optimized through a software algorithm, so that interference of the bubbles is eliminated finally.

摘要： The present invention discloses an optical system for 3D printing and a control method thereof. The system comprises a laser device, a beam expanding system, a beam splitter, a spatial light modulator and a focusing system. The spatial light modulator is connected with a computer and configured to generate a modulation pattern after receiving the target modulation pattern generated by the computer. A light beam emitted by the laser device is expanded into a parallel light beam by the beam expanding system and then irradiates on the beam splitter. A part of the expanded light beam reaches the spatial light modulator for modulation after passing through the beam splitter, then the modulated light beam is reflected to the beam splitter, and a part of the modulated light beam is focused by the focusing system and then irradiates on a target plane for 3D printing.
