Abstract

The invention relates to the technical field of modern monads, in particular to a laser display hand-held measuring instrument. A laser display hand-held measuring instrument, which consists of a central processing unit, a photoelectric conversion device, a program download interface module, a data transmission unit, a passive key unit, an external clock crystal oscillator circuit, a power supply unit and a display unit, wherein the photoelectric conversion device, the program The download interface module, the data transmission unit, the passive button unit, the external clock crystal oscillator circuit and the display unit are all directly connected with the microcontroller; the power supply module is connected with the data transmission unit, the central processing unit and the photoelectric conversion device respectively. The invention overcomes the shortcomings of the prior art and realizes low cost. The single-point test system can realize portable high-precision measurement of light color performance at low cost, and can realize luminous flux, illuminance uniformity, chromaticity uniformity, Accurate testing of main light and color properties such as contrast.

Description

Technical field [0001] The invention relates to the technical field of modern singletons, in particular to a laser display handheld measuring instrument. Background technique [0002] Laser display is a display technology that uses red, green, and blue (RGB) lasers as the light source, which can reproduce the rich and brilliant colors of the objective world most truly, and provide more shocking expression. The ultimate goal of my country's laser display research and development is to promote laser display technology to industrialization in the next few years. In this context, the detection of the light and color performance of the laser display system is also becoming more and more important. However, the current detection systems of various light and color performances and various chromaticity illuminance meters mainly target incoherent light sources with a wide spectral range, and have the disadvantages of high cost and low detection accuracy. Summary of the invention [0003]...
