Delay Signal Counter
Product Overview
The delay signal counter is an instrument widely used in scientific research fields such as high-speed signal analysis and control, precise delay adjustment, and trigger-based counting. In recent years, with the development of quantum cryptography, the delay signal counter has become an essential tool for experimental studies on quantum signals.
The WT-DSC series delay signal counter primarily provides delay and counting functions. The device supports multiple standard levels—including LVTTL, LVPECL, NECL, and CML—as well as custom-level inputs. The counting circuit uses a clock crystal with an error of no more than 1 ppm, and the maximum counting frequency can reach 1.25 GHz. It supports adjustable delays ranging from 0 to 27.5 ns, and the delay channels can output signals at either LVTTL or LVPECL levels.

Atmospheric Turbulence Simulation Experimental System
The atmospheric turbulence simulation experimental system is built upon a spatial light modulator (SLM) to create a platform for simulating atmospheric turbulence conditions. By leveraging Kolmogorov’s statistical theory of turbulence and the power spectral density method, it generates dynamically adjustable turbulent phase screens. The system supports adjustment of subharmonic orders, enabling the creation of random phase screens that accurately reflect the statistical characteristics of turbulence. The software integrates a multidimensional parameter-control module that encompasses key variables such as phase-screen resolution and size, atmospheric coherence length (r0), inner and outer turbulence scales (l0 and L0), beam wavelength, beam waist radius, and propagation distance, thereby facilitating fine-grained simulation of turbulence intensity and propagation scenarios. Real-time loading of phase screens onto the SLM enables wavefront modulation, while the system also provides synchronous support for visual analysis of phase screens, import and export of image files, and data storage, thus offering a high-precision experimental environment for research on laser propagation under atmospheric turbulence interference and for validation of adaptive-optics algorithms.
