BOJIONG specializes in the development of high-end optical interferometry and inspection equipment. It is a leading manufacturer and suppliers of wavefront sensors in China. The wavefront sensor, developed by a team of professors from Zhejiang University and Nanyang Technological University of Singapore, combines diffraction and interference to realize common four-wave transverse shear interference. Therefore, the four-wave transverse shear interferometer based on random coding hybrid grating not only has compact structure, simple instrument adjustment and stable interference fringes, but also can realize wavefront detection with arbitrary distortion. It can be used in wavefront sensing and wave aberration measurement of photographic projection objective.
BOJIONG Wavefront Sensor Variable shear rate Wavefront Sensor based on random coded hybrid grating; Based on the existing sensors, a transmission device with variable shear rate is designed. The equipment is highly integrated, the mechanism is simple, the adjustment is convenient, the measurement is flexible, the precision is high, and the universality is strengthened. Advantages of the wavefront sensor: single-path optical self-interference, no reference mirror, strong vibration resistance, no optical vibration isolation, 2nm RMS high phase resolution, simple and fast interference light path construction, support collimation beam, large NA convergence beam.
The BOJIONG Wavefront Sensor can obtain different shear rates by adjusting the forward and backward movement of the randomly coded mixed grating, so as to realize the four-wave front transverse shear interference, which can detect the transient wavefront in real time, and can detect the quantitative phase of biological cells. The continuous adjustable shear quantity enables the wavefront sensor to select the best shear rate for the specific wave front to be measured, the measurement is flexible, the measurement accuracy is high, and the universality is enhanced. Real-time dynamic detection, 3D real-time imaging, designed for optical processing enterprises, universities, units of measurement, research institutions researchers, scientific and technological paper writing personnel to provide reliable data.
