    Abstract: The invention relates to a photoarray (1), comprising: a plurality of cells (10), wherein each of said cells (10) comprises a means (20)that is configured to generate a photocurrent (I) being proportional to the intensity (L) of the light impinging on the respective cell (10), and wherein each of said cells (10) comprises a change detection circuit (100) connected to the respective means (20) for generating the photocurrent (I), which change detection circuit (100) is configured to generate an output signal merely in case a change event occurs at which said intensity (L) changes by a threshold amount (T, T′) since the preceding change event from the respective cell (10). According to the invention said means (20) for generating said photocurrent (I) is additionally also used to estimate the magnitude of the said photocurrent (I) being a measure of the brightness of the light at the respective cell (10).

    Abstract: The present invention provides a light beam measuring instrument that can securely receive light reflected by a sample. The light beam measuring instrument 1 includes an optical axis tilting mechanism 13 that includes a first tilting mechanism 131 and a second tilting mechanism 132. From the optical axis A1 of irradiation light beam emitted from a light beam source 112, the first tilting mechanism 131 tilts the optical axis A1 about the first tilting axis T1. The second tilting mechanism 132 tilts the optical axis A1 about the second tilting axis T2. The light beam measuring instrument 1 can receive the light reflected by the semiconductor chip C by means of operation of the optical axis tilting mechanism 13 even if the light reflected by the semiconductor chip C is tilted. Accordingly, this apparatus can securely perform measurement or inspection using the light beam.

    Abstract: A toner density is calculated from outputs of light-receiving elements based on a difference between a reflection property of a supporting member and a reflection property of a toner pattern. Light-emitting elements aligned in one direction that is inclined to a sub-direction emit a detection light in such a manner that a distance between adjacent spots falling on the supporting member in a second direction is equal to or smaller than a width of the toner pattern in the second direction. The light-receiving elements receive a reflected light reflected from the supporting member and/or the toner pattern. The light-receiving elements are aligned, opposed to the supporting member, in a one direction corresponding to the light-emitting elements.
