The panoramic annular optical system can instantaneously complete the imaging of the surrounding 360° range target. The planar cylindrical projection method can realize the super hemisphere imaging and project the object of the cylindrical field of view around the optical axis to the two-dimensional circular plane. Above, the central area is a blind spot. The panoramic belt system was successfully applied in Zhejiang University's pico-satellite No. 1 launched in 2007 and Zhejiang University's pico-satellite No. 2 launched in 2015 to achieve ground observation, and in pipeline inspection, medical endoscopy, security monitoring, driverless, etc. The camera has broad application prospects. Pico-satellite No.1 is a kind of skin satellite independently developed by Zhejiang University and has been launched three times. "Pico-satellite No. 1 satellite is a kilogram of micro-satellite. The satellite is mainly used for the verification of the pico-satellite platform and the verification of the microelectromechanical system technology.

Accelerometer

Cinque Terre

The accelerometer is generally composed of a sensitive unit, a displacement measuring unit and a signal processing unit. It is the core component of the inertial navigation system, and it is also used in many applications such as attitude detection, seismic detection, terrain detection, vibration measurement, and gravity gradient measurement. It plays an important role, and the application scenarios span the civil, industrial and military fields. At present, our group's MOEMS accelerometer adopts the principle of grating interference diffraction, combines the principle of optical detection with MEMS accelerometer technology, and overcomes the low accuracy of traditional accelerometer measurement. It also has easy integration, small size, light weight, and the advantages of optical measurement against electromagnetic interference and high precision.

Due to the late start of the domestic MOEMS accelerometer, the development level is low, and the performance is still insufficient. Therefore, the research team conducted research on several key technologies of measurement unit and sensitive unit, completed the feasibility demonstration and the construction of the prototype, and obtained the corresponding experimental results. The key technologies involved in the measurement unit include three-path compensation heterodyne measurement technology (to achieve ultra-high acceleration measurement accuracy), dual-wavelength super-heterodyne interference technology (to extend the linear range of acceleration measurement); key technologies involving sensitive units Research includes flexible structural design with ultra-high acceleration-displacement sensitivity (to achieve ultra-high acceleration measurement sensitivity), highly symmetrical structural design (to suppress off-axis crosstalk), and sensitive cell design methods to reduce temperature effects.
