## Abstract

A target material comprises a rubber sheet coated with a thermoluminescent material. When a bullet penetrates the target, as a result of the temperature rise the thermoluminescent material thermoluminesces indicating where the bullet went. A range is disclosed in which images of targets are projected onto the target material.

## Claims

### Claim 1

A target comprising a support member adapted to be penetrated by projectiles, said support member being formed from a resilient material which is not destroyed when a projectile passes therethrough and which locally increases in temperature as it is penetrated by said projectile, a coating of thermoluminescent material on said support member which is operable to luminesce in the area adjacent the position at which the projectile passes through the target.

### Claim 2 (depends on 1)

A target according to claim 1 wherein said resilient material is latex rubber.

### Claim 3 (depends on 1)

A target as defined in claim 1, further comprising means for projecting a visible image onto said target.

### Claim 4 (depends on 3)

A target according to claim 3 wherein the target extends over at least one wall of a closed room.
