The application relates to the technical field of three-dimensional topography measurement, in particular to a microscopic device, which has a first measurement mode and a second measurement mode. In the first measurement mode, the first measurement mode can be combined by a first illumination module, a first objective lens and an image acquisition module, and the measurement of a measured object can be realized by adopting the interference mode of first detection light and first reference light in an imaging light path. In the second measurement mode, the second measurement mode can be combined by a second illumination module, a second objective lens and an image acquisition module, and the measurement of the measured object can be realized by adopting second illumination light with a predetermined coding pattern in the same imaging light path. Thus, different measurement modes can be adopted according to user requirements, the same image acquisition module and the same imaging light path can be used to meet different measurement requirements of the measured object, the microscopic device has multiple functions, and the cost of the microscopic device and the cost of various types of measurement are reduced.

The utility model discloses a multifunctional multi-purpose ruler for constructional engineering, which comprises a protractor, angle lines are fixedly connected to the edge of the front surface of the protractor, a first scale is fixedly connected to the outer surface of the protractor, and first scale lines are fixedly connected to the top of the front surface of the first scale. According to the multifunctional and multipurpose ruler for constructional engineering, through the arrangement of the protractor, the first ruler and the second ruler, angle lines and the protractor are used in cooperation, different angles can be measured and drawn, the overall practicability is effectively improved, when the second ruler and the first ruler are located at the same horizontal position, the overall use length can be extended, and the practicability is improved. The second scale marks and the third scale marks are used in cooperation, the measuring range is enlarged, when the second scale is not used, the second scale can be folded to reduce the storage size, storage and carrying are convenient, different measuring requirements are met, meanwhile, surveying and mapping tools do not need to be frequently replaced in the drawing process, and the working efficiency is greatly improved.
