So researchers used a statistical analysis to measure the orientation and shape of the galaxies to find small distortions due to so-called weak lensing.

所以研究人员使用统计分析来观测星系的位置和形状，从而找出由弱透镜效应造成的微小偏移。

At present, photothermal deflection technology and surface thermal lensing technology are widely applied in weak absorption measurement.

目前，广泛使用的测量弱吸收的方法有光热偏转技术和表面热透镜技术。

The camera should be able to gather enough data to allow all four possible avenues for exploring dark energy: galaxy clusters, supernovae, large-scale galaxy clumping and weak gravitational lensing, at the same time.
