Description

Laser instrument electrical property detects instrument

Technical Field

The utility model belongs to the technical field of the laser instrument detects, especially, relate to a laser instrument electrical property detects instrument.

Background

The barcode scanning module can be used for scanning and decoding a two-dimensional code and generally comprises a light supplementing LED, an indicating LED, an image sensor, a lens and a plurality of active and passive components. Sweep a yard module and need a LED as the pilot lamp usually to be swept the bar code position at the location of sweeping yard in-process, but the transmitting power of ordinary LED lamp is lower, and the directionality is relatively poor, is being swept the bar code and sweep yard module distance when far away, and the light intensity of LED lamp can weaken, and the facula can grow, can't play fine indicative function. Therefore, some applications requiring remote code scanning usually use a laser as an indicator light, and the high power and good directivity thereof facilitate remote indication.

However, the laser usually has problems of laser power drift, current drift, laser spot position shift, laser spot chromatic aberration drift, etc. due to process control and the like. A laser module for sweeping sign indicating number location usually need weld to sweep on the printed circuit board of sign indicating number module, if the laser instrument that has a problem welds to printed circuit board, can cause very big difficulty to subsequent finished product test, rework, consequently need detect the operating current, the facula position and the facula colour difference of laser instrument.
