The invention discloses a testing method for the shock wave attenuation rate of an explosive-removal personal protective device. The testing method comprises the following steps that (1) the explosive-removal personal protective device is put on a human body model, a free field pressure senor or a wall face pressure sensor is installed on the outer portion of the explosive-removal personal protective device, and the external shock wave overpressure value P0 when an explosion occurs is obtained; (2) a free field pressure senor or a wall face pressure sensor is installed in the human body model, the internal shock wave overpressure value P1 when the explosion occurs is obtained, and thus calculation formula of the shock wave overpressure attenuation rate of the explosive-removal personal protective device is D1=(P1-P0)/P0*100%. The testing method has the advantages that references can be provided for quantizing the shock wave resisting performance test of the explosive-removal personal protective device, and a reliable testing means can be provided for the comparison of two protective devices. The testing method further has the advantages that background noise is removed, and the maximum value of a curve is found.

A new concept of the LCD light-switching optical filter allowing for very high, electrically controlled, continuously variable light attenuation (up to ≧100,000) optimized/symmetrized for the light incidence along the normal to the LCD plane is proposed. The new LCD light-switching optical filter also exhibits very low light attenuation dependence for the oblique incidence of light within a limited cone of angles off the normal incidence direction in compliance with the international safety and quality regulation EN 379 for personal protection equipment.

According to the invention the problem is solved by specific, novel modification of the general principle of highly twisted nematic LCDs, allowing for the adaptation of the light transmission/driving voltage characteristics to specific requirements of the driving electronics as well as “symmetrizing” the overall optical birefringent properties, which in turn results in a high degree of their angular compensation.
